Ask anything — all models respond at once…

Simulated preview — live responses stream in real time

You already use multiple AI tools.
You just do it the slow way.

Most people open one AI, get an answer, open another in a new tab, ask again, then a third — comparing answers in their head. That's the problem Compare solves.

Without MultipleChat
  • →Open one AI. Ask. Wait.
  • →Open another in a new tab. Ask the same thing again. Wait.
  • →Open a third. Repeat.
  • →Try to compare three answers across three tabs.
  • →Copy. Paste. Reformat manually.

~8 minutes per comparison. Every time.

With MultipleChat Compare
  • →Type your prompt once.
  • →All models respond simultaneously in one view.
  • →Differences are visible at a glance.
  • →Pick the best answer or combine insights instantly.
  • →No tabs. No copy-pasting. No manual formatting.

~30 seconds. Same result, less effort.

How it works

Three steps. That's it.

1

Pick your models

Choose any combination — two models or all four. Mix and match anytime from the tab bar.

2

Type your prompt once

One input, sent to all selected models at exactly the same time. No repeating yourself.

3

See all answers side by side

Responses stream in real time in parallel columns. Spot differences instantly.

When compare mode matters most

Some tasks need more than one opinion. These are the situations where running all models in parallel pays off.

Fact-checking

Ask a factual question and see where models agree — and where they don't. Conflicts surface errors you'd otherwise miss.

Writing & editing

Get multiple different rewrites of the same paragraph at once. Pick the tone that fits without running prompts one at a time.

Code review

Paste code and let multiple models review, refactor, or debug it in parallel. Different models catch different issues.

Research

Ask a research question and let each model cover it from its knowledge base. Cross-reference answers for the most complete picture.

Business decisions

Ask "should we do X?" and see models analyse it from different angles. Faster than consulting multiple tools separately.

Finding the best model for a task

Not sure which model suits your use case? Compare them with your actual prompt and decide with real evidence.

Compare vs. Collaborate — what's the difference?

MultipleChat has two ways to use multiple models. Here's when to use each.

Compare Mode

All models get the same prompt at the same time. They respond independently. You see all answers in parallel columns.

Best for:

  • → Seeing how different models approach the same question
  • → Fact-checking by cross-referencing answers
  • → Finding the best model for a specific task type
  • → Getting multiple writing variations at once
AI Collaboration Mode

Models work in sequence, parallel or iteratively. The output is a single verified answer.

Best for:

  • → Getting one polished, cross-verified answer
  • → Drafting then refining in a single workflow
  • → Automatically catching errors before you act
  • → Deep research with fact-checking built in

Both modes are included. Switch anytime from the same interface.

Stop switching tabs.
