MultipleChat AI

MultipleChat — all the AIs in one workspace

Most AI users end up paying for three or four subscriptions and copying the same prompt between tabs. MultipleChat puts the leading models — ChatGPT, Claude, Gemini, Grok and Perplexity Sonar Pro — behind one account, one interface and one bill, and adds the layer that single-model tools are missing: the ability to check one AI's answer against another.

Three ways to work

One AI. Pick the model you want and chat normally, the way you would in ChatGPT or Claude — with files, documents and in-chat editing. Compare Mode. Send one prompt to up to four models at once and read the answers side by side in real time, streaming simultaneously. AI Team (AI Collaboration). Ask once and the models work together: ChatGPT drafts, Claude reviews, Gemini orchestrates and fact-checks, Grok surfaces disagreements. You get one combined answer plus the tools to inspect it — individual model Responses, Sources, Disagreements, and Team Reason for a deeper critique. Nine modes are available: Smart, Conversation, Ensemble, Co-operative, Debate, Simulation, Expert, Humanize and Research.

Agents that improve every answer Prompt Optimizer writes the detailed prompt for you, Web Search pulls source-backed results via Perplexity Sonar Pro, Auto Fact Check reviews responses for factual risk, and Team Reason stress-tests an answer for hidden assumptions, root causes, blind spots and long-term consequences. Use one or combine all four.

Studios — turn answers into deliverables Document Studio (DOCX, PDF, Markdown, HTML), Presentation Studio (editable PPTX), Excel Studio (XLSX, CSV, TSV) and Image Studio (five image models from one prompt, plain-language editing, background removal, chained edits). OCR via Mistral, Claude and Google Drive reads scanned PDFs and image-heavy files before the AI works on them. Studios have their own usage allocation, separate from chat.

Projects and context Set instructions once, import files from Google Drive or code from GitHub, and every model works from the same shared knowledge. Existing chats can be imported so nothing has to start over.

AI Humanizer Rewrite stiff or obviously AI-written text — inside AI Collaboration, or as a dedicated project trained on your own writing sample.
