Five models. One place.
MultipleChat is an AI chat workspace where you talk to ChatGPT, Claude, Gemini, Grok and Perplexity in one place, and you can start with a free account. Ask once, compare the answers side by side, and keep the best one — not just the first one.
Free daily messages · No credit card required · Pro from $20/month
Every AI chatbot has blind spots. A single chatbot gives you one model's view; MultipleChat lets you check it against four others without opening more tabs or paying for more subscriptions.
| What you need | One AI chatbot | MultipleChat |
|---|---|---|
| Models | One provider's models | ChatGPT, Claude, Gemini, Grok and Perplexity Sonar Pro in one workspace |
| Comparing answers | Paste the prompt into other tabs yourself | Compare Mode: one prompt, every answer side by side |
| A second opinion | Ask the same model again | AI Collaboration modes where models critique, debate and refine one answer |
| Checking facts | You check the sources yourself | Sources, AI Disagreements and Auto Verification (paid plans) |
| Web search | Depends on the provider and plan | Perplexity Sonar plus each model's built-in search, with citations |
| Files and context | Files are often tied to one chat | Projects with files, standing instructions and Drive, GitHub or Dropbox imports |
| Price for several models | A subscription per provider (ChatGPT Plus $20, Claude Pro $20, Google AI Pro $19.99) | One Pro plan at $20/month |
| Getting started | Free tiers cover that provider's own models | Free account with free daily messages, no credit card |
Provider prices are US list prices per month as of October 2026 and can vary by country.
Three steps from sign-up to your first compared answer.
Go to multiplechat.ai and sign up with email, Google or Apple. No credit card needed. You can also try it without an account on a small daily allowance.
Choose one model in the selector next to the send button, click Compare to see several answers side by side, or choose AI Team to let models work together.
Type your message, attach files with the paperclip if you need to, then keep going with the answer you trust. In Compare Mode, Reply continues with just that model.
The models are trained differently and tuned for different things. Use this as a starting point, not a ranking.
| Model | Good first choice for | Try it in |
|---|---|---|
| ChatGPTOpenAI | Everyday questions, structured answers, coding help and brainstorming | Solo chat or Smart (Chain) |
| ClaudeAnthropic | Long-form writing, editing, careful analysis and a natural tone | Co-op or Humanize |
| GeminiGoogle | Research synthesis, long documents and multi-step analysis | Ensemble or Expert |
| GrokxAI | Current topics, direct answers and a contrasting point of view | Debate |
| PerplexitySonar Pro | Live web research and answers with source citations | Research mode or web search |
Not sure? Send the prompt to all of them in Compare Mode and keep the best answer.
Use one model when that is all you need, or let several work on the same question.
One model of your choice. Fast and simple for straightforward questions.
Every selected model answers in its own column, live. See where they agree and differ.
One model takes a position, another challenges it, and the final answer uses the strongest arguments.
Two models search the web in parallel; contradictions are resolved with the better-supported sources.
More AI Team modes: Smart (Chain), Ensemble, Co-op, Expert, Humanize, Simulation and Conversation. See how each mode works
In collaboration modes the final model lists the issues it found in the draft, so you see where models diverge instead of one confident answer.
On paid plans, another model and web sources check factual claims, source support and hallucination risk right after each answer.
Keep files and standing instructions together. Every chat in a project uses them, and files can come from Google Drive, GitHub or Dropbox.
Attach PDFs, DOCX, XLSX, PPTX, images and code. Scanned PDFs are OCR'd, so the AI can read them too.
Perplexity Sonar plus each model's built-in search bring in current information with citations.
Chats save automatically. Pin, rename or export them, and import your ChatGPT exports to keep old conversations.
What you can do at MultipleChat
MultipleChat is not just another single-model chat page. You can use ChatGPT, Claude, Gemini, Grok, and Perplexity in one workspace, compare their answers side by side, switch models mid-task, or let the models talk to each other until they produce a stronger final answer.
Send one prompt to several models and see which answer is clearer, more accurate, more creative, or more useful.
Ask ChatGPT to draft, Claude to critique, Gemini to restructure, and Grok to push back before MultipleChat merges the result.
Paste AI text and use a different model to rewrite rhythm, tone, and wording so the result sounds less generic.
Upload files, use web search, keep project context, rewrite emails, improve essays, draft reports, and create final content in one place.
You can start with a free account: free daily messages, no credit card required. The free plan has daily usage limits and basic model access, and in Compare Mode the Claude and Grok columns are locked. You can also try MultipleChat without signing in, with a small daily allowance. The Pro plan ($20/month) adds higher limits, all five chat models, AI Collaboration modes, Studios and Auto Verification.
MultipleChat does not use your conversations, files or other personal data to train AI models, and calls to AI providers run under agreements that exclude your data from training. Data is encrypted in transit (TLS) and at rest (AES-256). Your chat history is private to your account and you can delete chats at any time. MultipleChat is operated by NLP GmbH, a Swiss company, under the Swiss FADP and the GDPR. Details are on the Security and Privacy pages.
There is no single best AI chatbot for every task. ChatGPT is a strong all-rounder, Claude is popular for writing and careful analysis, Gemini for research and long documents, Grok for a contrasting take on current topics, and Perplexity Sonar Pro for web research with sources. Because strengths change with every model release, the most reliable approach is to compare answers on your own question, which is what Compare Mode in MultipleChat does.
Yes. The model selector sits next to the send button, so you can pick a different model or switch to AI Team mode for your next message. In Compare Mode, each model's column has a Reply button, so you can continue the conversation with just the model whose answer you liked.
Within a conversation, follow-up messages build on what was said before, and your chats are saved automatically so you can pick them up later. For context that should carry across chats, use Projects: add files and standing instructions once, and every chat in that project uses them. Project files can be uploaded or imported from Google Drive, GitHub or Dropbox.
ChatGPT is OpenAI's chatbot and runs OpenAI models. MultipleChat is an AI chat workspace that includes ChatGPT models alongside Claude, Gemini, Grok and Perplexity, so you can compare their answers side by side or let them review each other's work. You can also import your ChatGPT chat exports into MultipleChat.
An AI chatbot is a program you talk to in plain language. It is powered by a large language model that reads your message and writes a reply, and it can answer questions, draft and edit text, explain code, summarize files and help with research. ChatGPT, Claude, Gemini, Grok and Perplexity are all AI chatbots.
Yes. Compare Mode sends one prompt to several models and shows each answer in its own column. AI Collaboration modes such as Smart, Debate, Expert, Co-op and Research go further: the models draft, critique and refine one final answer together.
Run ChatGPT, Claude, Gemini, Grok and Perplexity side by side. See where they agree, where they disagree, and which one gives you the best answer.
