Getting Started

Welcome to MultipleChat

MultipleChat runs ChatGPT, Claude, Gemini, and Grok together — coordinating them into structured multi-step pipelines so they build on, verify, debate, or challenge each other's answers.

AI Collaboration

Assign models to slots, pick a mode — Smart, Debate, Humanize, Research, and more. Each mode is a different orchestration pipeline.

Two Ways to Make Files: Chat or Studios

MultipleChat can produce real Word documents, Excel spreadsheets, and PowerPoint presentations in two places — and they're for different situations:

Make it in chat

Just ask. "Write me a memo about the new policy" or "make me a Q3 budget spreadsheet" — the AI generates the file inline and gives you a download link, without leaving the conversation.

Best when: You want one quick file, you're already deep in a chat, or you want the file to reference the conversation context.

Open a Studio

Studios are dedicated workspaces with templates, style presets, side-by-side previews, refinement panels, and the ability to run two models on the same document at once.

Best when: You want polished output, deliberate styling, multiple revisions, or you're processing a large file you've uploaded.

Both paths produce the same kinds of files (DOCX, XLSX, PPTX, PDF). Pick whichever feels right for the task.

Account Setup#

MultipleChat uses Auth0 for authentication. No password is stored on our servers — Auth0 handles the sign-up and login flow.

Creating an Account

1

Visit multiplechat.ai and click Get Started

2

Enter your email and choose a password, or continue with Google

3

Verify your email address

Check your inbox and spam folder for the verification link

4

Complete onboarding and start chatting

Trying It Without an Account

You can use MultipleChat without signing in to try it out. Anonymous use comes with a small daily allowance of messages and uses a fixed default model setup. To unlock collaboration modes, file uploads, projects, and the Studios, create an account.

Changing Your Password

Because authentication runs through Auth0, password changes go through Auth0's password reset flow — there is no password-change form inside the app.

  1. 1. Go to the login page and click Forgot password
  2. 2. Enter the email address associated with your account
  3. 3. Auth0 sends a password reset link to that email
  4. 4. Follow the link to set a new password

If you signed up with Google ("Continue with Google"), your password is managed by Google — not Auth0.

Your First Chat#

Single Model Chat

1

Click the model selector next to the send button and pick one model

2

Type your message and press Enter

AI Team (Collaboration) Chat

1

Select AI Team from the model selector — the AI Team configuration modal opens

2

Tap model icons to assign them to slots (slot 1 = first model, slot 2 = second model). Pick a mode from the pill buttons at the bottom of the modal.

3

Click Go Live to save and close the modal

4

Send your message — the selected mode runs and streams the result back token by token

Good first prompts to try

  • • "Explain how central banks control inflation" — try Smart (Chain)
  • • "Should I use microservices or a monolith for my SaaS?" — try Debate
  • • Paste an AI-generated paragraph and ask to rewrite it — try Humanize
  • • "What are the latest developments in fusion energy?" — try Research
  • • "Make me a pitch deck for a coffee subscription startup" — Claude calls a tool and gives you a real .pptx file

How AI Collaboration Works#

When you send a message in AI Team mode, the selected mode routes your prompt through a specific sequence of model calls. The final model streams its answer back to you token by token, with a live progress indicator while intermediate steps run.

The General Flow

1

Configure your team — assign models to slots and pick a mode in the AI Team modal

2

Slot 1 model processes your prompt and produces an initial response

3

Slot 2 model receives that output and performs the mode's specific task on it

4

The final synthesized answer streams live to your screen

Every collaboration mode uses two models — slot 1 produces something, slot 2 does the mode's specific job on top of it (review, critique, counter, fact-check, and so on).

All Collaboration Modes#

Each mode is a distinct pipeline. Choose based on what you need from the result.

Smart (Chain)

Slot 1 generates a complete draft. Slot 2 acts as a domain expert — it takes the draft as a foundation, adds depth, reasoning, analogies, and examples, and challenges any facts Slot 1 got wrong. Sources from both models are combined in the final output.

Best for

Comprehensive explanations, research questions, anything requiring depth and accuracy

Flow

Slot 1 drafts → Slot 2 deepens and critiques → streamed final answer

Humanize

The model rewrites the content you provide — it does not answer it. It removes AI clichés ("delve into", "it's important to note", "leveraging"), varies sentence rhythm and length, and preserves every fact and meaning exactly. Paste AI-generated text as your prompt and get back a natural-sounding rewrite.

Best for

Making AI-written content sound human — blogs, reports, emails, marketing copy

Note

Paste the text you want humanized as your prompt — don't ask a question

Debate (Competitive)

Models argue iteratively over multiple rounds. Slot 1 takes a clear position and states its arguments. Slot 2 counters. Slot 1 replies to the counter. This back-and-forth continues until a synthesis is produced that draws the strongest arguments from both sides.

Best for

Decisions, trade-off analysis, "should I do X or Y" questions

Flow

Slot 1 position → Slot 2 counter → Slot 1 rebuttal → synthesis

Ensemble

Both models answer your question in parallel — completely independently, with no knowledge of each other's response. The outputs are then merged, extracting and combining the best parts of each into a single, more complete answer.

Best for

Getting broad coverage without one model influencing the other

Flow

Slot 1 and Slot 2 run in parallel → outputs merged into one answer

Co-op (Cooperative)

Models build on each other iteratively. Slot 1 writes a complete draft. Slot 2 reviews it and suggests improvements. Slot 1 then produces a final version that incorporates those suggestions.

Best for

Writing tasks, code, structured documents where iterative quality improvement matters

Flow

Slot 1 draft → Slot 2 review & suggestions → Slot 1 final version

Simulation

Models collaboratively play out a scenario over multiple rounds. Slot 1 sets up the scenario, defines key actors and variables, and runs Round 1. Slot 2 continues the simulation in Round 2. This alternates until the scenario resolves.

Best for

Scenario planning, hypotheticals, roleplay, strategy exercises, creative writing

Flow

Slot 1 setup + Round 1 → Slot 2 Round 2 → alternating rounds → conclusion

Expert

Slot 1 produces an initial analysis. Slot 2 then adds expert-level depth — the why behind the what, technical depth, strategic implications, trade-offs from multiple professional perspectives. The result reads like a domain specialist's take rather than a general explanation.

Best for

Deep technical or strategic questions where surface-level answers aren't enough

Flow

Slot 1 initial analysis → Slot 2 expert depth → final answer

Verification

Slot 1 answers the question. Slot 2 then fact-checks every claim, corrects errors, and adds missing critical information before the final answer is delivered. Different from the post-response Verified badge — Verification mode is the collaboration pipeline itself, designed for when accuracy is the whole point.

Best for

Claims, statistics, historical or scientific facts that must be right

Flow

Slot 1 answers → Slot 2 fact-checks and corrects → verified final answer

Research New

Both models answer your question independently using live web search in parallel. Their sourced answers are then compared to find genuine contradictions. A synthesis step resolves disagreements by picking the better-supported claim and combining the strongest sources from both models.

Best for

Current events, fact-checking, questions where accuracy and up-to-date sources matter most

Flow

Both search in parallel → compare findings → synthesize with best sources

Web search is automatically enabled when you select Research mode.

Quick guide: which mode to use

  • • Writing and content: Humanize or Co-op
  • • Deep research and accuracy: Research, Verification, or Smart (Chain)
  • • Decisions and trade-offs: Debate (Competitive)
  • • Broadest coverage from multiple perspectives: Ensemble
  • • Domain depth and technical analysis: Expert
  • • Scenarios and hypotheticals: Simulation

Compare Mode#

Compare Mode is different from any of the collaboration modes. Instead of combining models into one answer, it shows you each model's response to your prompt side by side, in its own column, streaming live in parallel. You see exactly where they agree, where they differ, and which model handled the question best.

Turning It On

Click the Compare button in the top toolbar. The screen splits into columns — one per model — and your input bar moves to the bottom. Type a prompt and every selected model answers at once. Compare Mode is desktop-only (the columns don't fit on small screens) and is part of the Smart plan.

What You Can Do

Pick which models to compare — toggle ChatGPT, Claude, Gemini, and Grok on or off in the model bar above the columns
Continue with one model — each column has a Reply button so you can keep the conversation going with just that model
Stop everything — abort all running streams at once if you spot what you needed early
Mobile fallback — on phones, the comparison shows one model at a time with a switcher

Compare vs Ensemble

Both run models in parallel. Ensemble merges the outputs into a single combined answer — you don't see each model individually. Compare Mode keeps each response separate so you can read, judge, and continue with whichever you prefer.

What Claude & Friends Can Do In Chat#

You don't always need to open a Studio. The AI in regular chat can produce real files and analyze your uploads directly — just ask in plain language and the model will hand you back a downloadable file or a structured analysis.

What You Can Ask For

Create a Word document

"Write me a one-page memo to my team about the new policy" — get a real .docx file back, with optional PDF.

Create a spreadsheet

"Make me a Q3 budget tracker with categories and totals" — returns a real .xlsx with formulas, formatting, and charts.

Create a presentation

"Build me a 10-slide pitch deck about a coffee subscription startup" — returns a styled .pptx.

Generate an image

"Draw a flat illustration of a fox reading a book" — image appears inline in the chat.

Modify your document

Upload a DOCX and say "make this more formal" or "translate to Spanish" — get back the rewritten file.

Analyze your file

Upload a long PDF or large spreadsheet and ask questions — the AI pulls the right parts to answer accurately.

In-chat vs Studios — when to use which

In-chat is fastest when you want one quick file inside a conversation. The Studios are better when you want to iteratively refine, pick templates and styles deliberately, run two models in parallel for the same document, or process larger files with more options. Both produce the same kinds of files.

Document Studio#

Document Studio generates and processes Word documents (.docx) from natural language. Generate from scratch using a template, upload an existing file to transform it, refine the result iteratively, and preview the output as a live HTML preview before downloading.

Why a Studio instead of just chat? Document Studio gives you templates with built-in section structures, side-by-side competitive drafts from two models, a quality-review summary, a live preview before download, and a refine panel to iterate on the result. Chat is faster for one-shot files; Studio is better when the document matters.

Document Templates

Each template defines a structural blueprint — the sections the AI will populate:

Business Report — executive summary, findings, analysis, recommendations
Proposal — problem statement, solution, methodology, timeline, budget
Whitepaper — abstract, background, methodology, findings, references
Case Study — challenge, approach, implementation, results, lessons learned
Statement of Work — scope, deliverables, milestones, acceptance criteria
Meeting Minutes — attendees, agenda, discussion, decisions, action items
Cover Letter — opening, qualifications, value proposition, closing
Resume / CV — summary, experience, skills, education, certifications
Internal Memo — purpose, background, discussion, action required
Creative / Essay — introduction, body sections, conclusion
Custom / Freeform — AI decides the best structure from your topic and instructions

Collaboration Modes

Document Studio has its own generation collaboration modes (separate from the main chat modes):

Single Model

One AI model generates the complete document.

Cooperative Writing

Model A drafts → Model B reviews and suggests improvements → Model A produces the final version. After generation, you'll see a quality summary showing strengths, weaknesses, and how many improvements were applied.

Competitive Drafting

Two models each produce a full, independent draft. You see both side by side and can pick or merge the best parts.

Processing an Existing Document

Upload a DOCX, PDF, or TXT file and apply one of these actions:

Improve — fix grammar, enhance clarity and professionalism
Summarize — condense into a shorter version keeping key points
Expand — add detail, examples, supporting evidence
Restructure — reorganize for better flow and logical progression
Translate — translate to any language, preserving formatting
Tone Adjust — shift to formal, casual, technical, or persuasive
Extract Actions — pull all action items, decisions, and takeaways
Merge — combine multiple source documents into one

Export Formats

Every generated document can be downloaded as DOCX, PDF, Markdown (.md), or HTML. A live HTML preview is shown before you download anything.

Iterative Refinement

After generating, use the Refine panel to describe what you want changed in plain language. The studio applies your instructions and updates the live HTML preview. Repeat as many times as needed before downloading.

Excel Studio#

Excel Studio is a full AI-powered spreadsheet environment. It generates workbooks from scratch, processes and transforms your existing files, lets you refine results with plain-language instructions, runs 26 instant operations that need no AI, and includes a Formula Assistant that writes and explains any Excel formula on demand.

Why a Studio instead of just chat? Excel Studio profiles your data on upload (rows, missing values, per-column stats), lets you click columns to target specific operations, runs 26 free instant tools (cleaning, formatting, formulas) without using AI credits, and includes a dedicated Formula Assistant. Chat can make a spreadsheet; Studio is for working with one.

1. Generate a Spreadsheet from Scratch

Describe what you need in plain language. Choose a template, a style preset, and how many rows you want. The AI builds a realistic workbook with proper formulas, formatted columns, summary rows, and charts where appropriate — all in one step.

Available templates:

Budget Tracker — income/expense categories, subtotals, variance
Profit & Loss Statement — revenue, COGS, expenses, net income, % of revenue
Cash Flow Forecast — opening/closing balance, inflows, outflows, runway
Loan Amortization — PMT schedule with principal, interest, remaining balance
Invoice — line items, quantity, unit price, tax, total
Sales Pipeline / CRM — deals, stages, probability, weighted forecast
Employee Roster — departments, salary, tenure, next review date
Inventory Tracker — SKUs, reorder point, unit cost, total value
Project Tracker — tasks, owner, dates, status, dependencies
OKR / KPI Scorecard — objectives, key results, targets, traffic-light status
Comparison Matrix — options vs weighted criteria, scoring, ranking
Expense Report — dated expenses, categories, vendor, totals by category
Custom / Freeform — AI decides the best structure for your description

2. Process an Existing Spreadsheet

Upload an existing .xlsx or .csv file. When you upload it, the studio automatically profiles your data — showing you row count, column count, duplicate rows, missing values, and per-column statistics (min, max, mean for numeric columns) before you even run anything. The column list is interactive — click columns to select which ones the AI should focus on. Then apply an action:

Improve — AI analyzes your data and adds useful formulas, formatting, and charts
Add Formulas — detect numeric columns and insert SUM, AVERAGE, calculated columns
Add Charts — AI picks and inserts the most appropriate chart types
Format — apply professional table style, number formats, conditional formatting
Translate — translate all headers, labels, and text to another language
Restructure — reorganize sheets and columns for better usability
Custom — describe anything in plain language and the AI applies it

You can add free-text instructions alongside any action to further guide the AI — e.g. "Translate headers to Spanish, add a pivot summary by region".

3. Iterative Refinement

After generating or processing, use the Refine panel to describe changes in plain language — "Add a column that calculates 30-day average", "Change the header colours to dark blue", "Add a pie chart to the Summary sheet". The AI modifies only the parts you asked about and rebuilds the file. Repeat as many times as needed.

4. Formula Assistant

The Formula Assistant is a dedicated tab that writes Excel formulas on demand. Describe what you want in plain English, optionally paste your column headers as context, and get back:

  • • The exact formula ready to paste into a cell
  • • A step-by-step explanation of how it works
  • • Edge-case warnings (e.g. what happens when there's no match)
  • • Alternative formulas for the same result

Example requests:

  • • "Find the last purchase date for each customer in column A, looking up column B in the orders sheet"
  • • "Sum column D only where column C says 'Approved' and column E is greater than 1000"
  • • "Calculate the number of working days between two dates excluding weekends"

5. Free Tools (no AI, instant)

These run instantly — no AI call needed. Upload a file on the Tools tab and click any card:

Trim whitespace
Remove duplicate rows
Standardize text case
Fix date formats
Split column by delimiter
Merge columns
Remove empty rows/cols
Forward/back-fill blanks
Add summary row
Running total column

Data bar formatting
Threshold highlighting
Freeze header row
Auto-fix number formats
Auto-fit column widths
Pivot/summarize to sheet
Transpose rows/columns
Split by category column
Add dropdown validation
Lock formula cells
Define named ranges

Export Formats

Download as Excel (.xlsx), CSV, or TSV. A live HTML preview of the spreadsheet is shown before downloading.

Presentation Studio#

Presentation Studio generates and processes .pptx files using a full design system. You control the style template, colour palette (preset or custom hex), font pairing, slide count, and can provide source content or instructions. Jobs run in the background with a live progress bar, and the finished file auto-downloads when ready.

Why a Studio instead of just chat? Presentation Studio gives you 6 style templates, 8 colour presets (or custom hex), font pairings, a precise slide-count control, and the ability to upload an existing deck and transform it (summarize, expand, redesign, translate). Chat picks defaults for you; Studio puts you in control of how the deck looks.

1. Generate a Presentation

Enter a topic, pick your settings, and click Generate. You can also paste source content — notes, an article, a brief — and the AI will structure slides from it rather than generating from scratch.

Style Templates

Business — professional, clean layout
Pitch Deck — investor-focused structure
Educational — clear sections, training-ready
Creative — bold visuals and layouts
Report — data-driven, metrics-focused
Minimal — content-first, low decoration

Colour Presets

Choose from 8 built-in colour schemes — Corporate, Modern Dark, Nature, Warm, Ocean, Sunset, Monochrome, Pastel — or override the primary, secondary, and accent colours with your own hex values using the colour pickers. A Reset button reverts custom colours to the active preset.

Font Pairings

Classic — Georgia / Calibri
Modern — Arial Black / Arial
Elegant — Garamond / Cambria
Clean — Helvetica / Helvetica
Bold — Impact / Verdana
Friendly — Trebuchet MS / Tahoma

Slide Layouts

The AI mixes layout types to avoid repetition. Every presentation always opens with a Title slide and ends with a Closing slide. Speaker notes are generated for every slide.

Title
Content
Two Column
Section
Stats
Quote
Image + Text
Closing

2. Process an Existing Presentation

Upload a .pptx file or pick one from your Projects (no need to re-upload anything you've already stored there). Apply an action with optional free-text instructions:

Summarize — condense into fewer, more impactful slides
Expand — add detail and supporting points to each slide
Redesign — restructure narrative flow, swap layouts for better impact
Translate — translate all text, preserve structure and formatting
Improve — fix grammar, sharpen bullet points, tighten writing
Add Speaker Notes — generate comprehensive notes for every slide
Reorder — reorder slides for better narrative flow and logical progression
Custom — describe anything in plain language

3. Download & Auto-Download

When a job completes, the .pptx file auto-downloads immediately. A result card also appears showing the presentation title, slide count, model used, and a manual download link in case the auto-download was blocked.

Jobs run in the background

Generation and processing happen in the background — you can keep working while a job runs and a real-time progress bar updates as it moves through stages. You'll be notified when it's ready.

Image Generator#

The Image Generator is a dedicated page (/image-generator) for creating images from text prompts. It supports 8 different image generation models, 6 aspect ratios, and includes an AI-powered prompt enhancer that automatically rewrites your prompt to be more detailed before generating.

Image Generation Models

DALL-E 3

OpenAI's flagship model. Strong at following complex instructions and producing coherent compositions.

SDXL

Stability AI. High resolution, strong at photorealistic and artistic styles.

SD3

Stability AI's third generation. Improved text rendering and composition.

Leonardo

Leonardo.ai. Excels at stylized, game-art, and cinematic imagery.

Ideogram

Strong at legible text within images — posters, logos, signs.

Recraft

Clean vector-friendly output, good for illustrations and design work.

Nano Banana

Google Gemini native image generation. Fast and versatile.

Nano Banana Pro

Higher quality Gemini image generation, more detailed output.

Generation Options

Aspect Ratios

1:1
16:9
9:16
4:3
3:4
21:9

Advanced Settings

  • • Quality — Standard or HD
  • • Style — Auto, photorealistic, vivid, etc.
  • • Negative prompt — what to exclude
  • • Seed — for reproducible results
  • • CFG Scale — how closely to follow your prompt

AI Prompt Enhancer

Click the Enhance button next to the prompt field before generating. An AI rewrites your prompt to add more descriptive detail — subject, lighting, style, composition — within 500 characters. The enhanced prompt replaces your original and you can edit it further before generating.

Writing Good Prompts

  • • Be specific about subject, setting, and mood
  • • Name a visual style: photorealistic, oil painting, 3D render, flat illustration
  • • Add technical detail: golden hour lighting, wide angle, shallow depth of field
  • • Use the Negative Prompt to exclude unwanted elements

Image Studio#

Image Studio is a separate page (/image-studio) for working with images you already have. Upload a photo or graphic and edit it with plain-language instructions, or remove its background with one click. Whereas the Image Generator creates images from text, Image Studio transforms images you provide.

What You Can Do

Upload an image

Drop a PNG, JPG, or WEBP file into the studio. The image becomes the base for everything that follows.

AI edit

Describe a change — "make this look like a watercolour", "change the background to a beach", "add sunglasses" — and the AI returns a modified version.

Remove background

Click the Remove Background button — the subject is automatically isolated and you get back a transparent PNG ready to drop into a design.

Download

Save the result as PNG or JPG. The original is preserved alongside the edits in the session.

Image Studio is for editing existing images. To create images from scratch, use the Image Generator.

Prompt Optimizer#

The Prompt Optimizer rewrites your message before you send it, making it clearer, more specific, and more actionable for AI models — without changing your intent or inventing new facts. It preserves URLs, numbers, filenames, and code blocks exactly as written.

How to Use It

1

Type your prompt in the message input. The Optimize button activates once you've typed something.

2

Click the Optimize button. A modal opens showing the rewritten prompt in an editable textarea.

3

Below the rewritten prompt, enrichment chips appear — clickable tags like Audience, Tone, Length, Structure, Images, Sources. Clicking a chip appends a placeholder line to the prompt that you can fill in.

4

Edit the optimized text directly if needed, then click Use to replace your original message — or Use & Send to replace and send immediately.

What the optimizer does

  • • Rewrites vague prompts into clear, imperative instructions
  • • Expands minimal prompts just enough to make them actionable — without inventing specifics
  • • Preserves your language — the output stays in the same language as your input
  • • Does not change facts, URLs, numbers, or code

Auto-Verification#

After a response is delivered, MultipleChat can automatically run it through a factual accuracy check using Google Gemini. The check analyzes whether the answer contains factual errors, outdated information, or missing context — and shows a badge on the response.

How It Works

Gemini receives your original question and the AI's response. In a single call it determines: (1) whether verification is even appropriate for this type of content, and (2) if so, what is factually correct and what issues exist. The result appears as a Verified badge if no issues are found, or an Issues found badge with a brief description if problems are detected.

Smart Skip Logic

Verification is automatically skipped — saving credits — for content types where factual checking doesn't add value:

Simple math and calculations
Code generation and debugging
Creative writing tasks
Opinions and subjective questions
How-to instructions
Definitions and grammar help

Auto-Verification runs automatically after the answer is delivered. Verification mode (in the collaboration modes section) is different — it's a pipeline that fact-checks during generation rather than after.

AI Disagreements#

In collaboration modes, the second model is always instructed to act as a quality reviewer and surface genuine issues with the first model's answer. These issues are collected, stripped from the visible response, and displayed as a separate AI Disagreements panel under the final answer.

What Gets Flagged

The reviewing model looks for issues in five categories:

Factual Errors

Incorrect dates, numbers, names, or claims

Missing Context

Important details that were left out

Outdated Information

Things that may have changed or been superseded

Oversimplifications

Nuance or complexity that was lost

Each disagreement is categorised and displayed with a colour-coded icon — red for factual errors, amber for missing items, orange for outdated info, blue for context issues. Click AI Disagreements under any collaboration response to open the panel.

The disagreements block is always stripped from the final answer text — it never appears inline in the response. It only surfaces when you explicitly click to view it.

Sources#

When web search is enabled or when Research mode is active, models collect source references for the claims they make. These are gathered from both models in a collaboration, deduplicated, and surfaced as a Sources button under the response.

Clicking Sources opens a modal showing each reference with its title, domain, and a clickable link. In Research mode, sources are grouped by which model found them, so you can see which model supported which claims.

Like disagreements, sources never appear inline in the readable response. The Sources button only appears when sources were actually found.

Individual Responses#

In collaboration modes, the final answer you see is the synthesized output of multiple models working together. But you can always inspect what each model produced individually by clicking the Responses button under any collaboration answer.

This opens a side-by-side modal showing each model's raw response before synthesis — with their individual web sources listed beneath each column if search was enabled. This is useful when you want to compare perspectives or understand exactly how the final answer was built.

For simple queries where the collaboration step was skipped to save time, the Responses modal will show a note explaining that a quick single-model response was used instead.

Projects#

A project is a named workspace that bundles files and standing instructions together. Every chat inside a project automatically has those files as context — the AI reads relevant chunks before answering without you needing to paste anything.

Creating a Project

1

Click New Project from the Projects page

2

Name the project and add optional instructions

Instructions are a standing system prompt — they shape how the AI behaves in every conversation inside this project

3

Upload files or connect Google Drive

Supported: PDF, DOCX, TXT, MD, CSV, JSON, and most plain-text code formats. Archives (.zip, .tar, .gz) are not supported.

4

Start a new chat inside the project — context is injected automatically

Google Drive Sync

Connect your Google account to import files directly from Drive. Select a folder or individual files to sync. Use Re-sync any time your files change — syncing is triggered manually to give you control over when files are updated.

How context retrieval works

When you send a message inside a project, MultipleChat searches across your indexed files to find the most relevant chunks for that specific query. Only those chunks are injected — not the entire file. If files have not been indexed yet, a banner appears with a one-click Index Now button.

File Uploads#

You can upload files directly in any chat — outside of a project — to give the AI context for that conversation. Click the paperclip icon next to the message input, or drag and drop a file into the chat window.

Supported Formats

Documents

PDF, DOCX, TXT, MD, CSV, JSON, XML

Images

PNG, JPG, GIF, WEBP — analysed visually by multimodal models

Code

JS, Python, HTML, CSS, and most plain-text code formats

How Files Are Read

MultipleChat picks the best path automatically based on the file:

  • • Small text and code files — injected directly into the conversation context so the AI can quote and reason over the whole content
  • • Spreadsheets, PDFs, large documents, and presentations — automatically routed to a Studio-style structured analysis so the AI can extract tables, sections, and statistics rather than treating them as walls of text
  • • Scanned PDFs — automatically OCR'd at upload time so handwritten or image-based PDFs are still readable

Per-plan upload limits apply to file size, total upload size, and how many files you can attach in a single message. Files uploaded into individual chats also expire after a period — long-term storage belongs in Projects.

Account & Billing#

Your account page (/account) shows your current plan, today's usage, and billing history. All subscription management happens here without contacting support.

Viewing Your Usage

The account page shows progress bars for how many collaboration (AI Team) messages and single-model messages you have used today against your daily limit. Limits reset at midnight UTC.

Changing Your Plan

Go to Account → Subscription. Upgrade and downgrade options are shown based on your current plan. You are redirected to Stripe for payment and then returned to the app. Changes take effect immediately.

Billing Portal

Click Manage Billing on the account page to open the Stripe Billing Portal. From there you can:

  • • Update your payment method
  • • Download past invoices
  • • Switch between monthly and annual billing
  • • Cancel your subscription

Cancelling

Cancellation is handled through the Stripe Billing Portal. Access continues until the end of the current billing period — nothing is cut off immediately on cancellation.

Chat History#

All your conversations are saved automatically and accessible from the chat history icon in the sidebar.

Managing Chats

  • • Rename — click a chat's title to edit it
  • • Pin — pin important chats to keep them at the top (up to 5)
  • • Delete — remove individual chats
  • • Delete all — clear your entire history at once

Exporting Your History

  • • Use the Export button in the history view
  • • Choose format: JSON, TXT, or CSV
  • • Export up to 1,000 chats at a time
  • • Export your full history or select specific chats

Privacy

Chat history is private to your account. Users who are not logged in do not have their chats saved between sessions. See our Privacy Policy for full details on data handling.

Sharing & Forking Chats#

You can share any of your chats as a read-only link. People who open the link see the full conversation in a clean view, and can fork it — creating a copy in their own chat history that they can continue in their own direction.

Sharing a Chat

1

Open any chat from your history

2

Click the Share action — a dialog opens with a shareable URL

3

Copy the URL and send it to whoever should see the chat

4

View counts and fork counts are shown in the dialog so you can see how the chat is being used

Forking a Shared Chat

When someone opens a shared chat link they can:

Read it — full conversation, including any AI Team configuration that was used
Fork it — clones the chat into their own history under "Fork of [original title]" so they can keep going from where you left off

Unsharing

Open the same Share dialog and click Unshare. The link stops working immediately — anyone who already forked the chat keeps their copy, but no new viewers can access the original.

Files attached to the original chat are not copied into forks — only the conversation text. If a forked chat references files, the new owner will need to upload their own copies.

Troubleshooting#

Models not responding

  • • Check your internet connection
  • • Refresh the page and try again
  • • Try a different browser or disable extensions
  • • Check for any known outages at multiple.chat

AI Team mode not working

  • • Make sure you have at least 2 models assigned (slots 1 and 2) in the AI Team modal
  • • Click Go Live to apply your configuration before sending
  • • Check the model selector shows "AI Team" — if it shows a single model name, collaboration is disabled

Compare Mode unavailable

  • • Compare Mode is desktop-only — switch to a larger screen if you're on mobile
  • • It's part of the Smart plan — upgrade if you're on Free or Pro
  • • Make sure at least two models are toggled on in the model bar before sending

Project files not being used

  • • If you see a "Files not yet indexed" banner, click Index now before sending your message
  • • After adding new files, use Re-sync to update the index
  • • Archives (.zip, .tar, .gz) are not supported — extract the files first

Slow responses

  • • Collaboration modes (especially Research and Debate) make multiple sequential AI calls — they are slower by design
  • • Turn off web search if you don't need real-time information
  • • Using 2 models instead of 4 significantly reduces response time

Studio job failed or stuck

  • • Studio jobs run in the background — wait for the progress indicator to complete fully before downloading
  • • If a job errors, try again with a simpler or shorter prompt to isolate the issue
  • • Large file uploads (PDFs, DOCX) take longer to process — the status updates in real time

Shared chat link not working

  • • The owner may have unshared the chat — ask them to re-share
  • • Check that you copied the full URL, including the token after /shared/
  • • If you're trying to fork and nothing happens, refresh the page once and try again
