AI sandboxes
Turn your files into answers—and finished work.
MultipleChat’s AI sandboxes let ChatGPT and Claude run code to analyze data, perform calculations and create downloadable files directly in your conversation. Upload a spreadsheet, work with eligible project files, or describe what you need. Your AI decides when code is useful and explains the results.
Choose between three sandboxes: ChatGPT, Claude, or MultipleChat. Use ChatGPT with Claude’s sandbox, or Claude with ChatGPT’s sandbox. You don’t need to write code yourself.
What you can do
Clean and transform files
Remove duplicates, standardize dates, reorganize columns, combine datasets and prepare data for your next task.
Run calculations
Work through forecasts, statistical analyses and scenario comparisons using executed code.
Create charts
Turn data into visual explanations, then adjust labels, colors or the information displayed.
Generate downloadable files
Create spreadsheets, documents, presentations, PDFs and structured data files.
Keep refining your work
Ask follow-up questions or revise earlier outputs within the same chat. Saved files can be reused when available; temporary execution environments may reset.
Choose your sandbox
- ChatGPT sandbox
- Run calculations, analyze files and create charts and downloads using OpenAI’s code-execution environment—even while chatting with Claude.
- Claude sandbox
- Analyze data, transform files and produce downloadable results with Claude’s code-execution environment—even while chatting with ChatGPT.
- MultipleChat sandbox
- Use MultipleChat’s tools for file analysis, OCR, conversion and file creation. This is the automatic option for Grok and Gemini.
Mix your assistant and sandbox: ChatGPT can use Claude’s sandbox, and Claude can use ChatGPT’s sandbox. Your chosen assistant receives the execution results and explains them in your chat. Both providers contribute to usage.
With Automatic selected, ChatGPT uses ChatGPT sandbox and Claude uses Claude sandbox. Saved account preferences and choices made for an individual chat take priority.
Change your choice through the Sandbox control below an answer or Account → File preferences.
Try asking—and download the result
- “Combine these sales files, remove duplicate orders and create an Excel summary.”
- “Calculate revenue by region and show the results in a chart.”
- “Compare these three pricing scenarios and export the calculations.”
- “Create a CSV from this table.”
- “Update the spreadsheet you created with these new figures.”
Downloads you can use
Supported downloads include Excel, Word, PowerPoint, PDF, CSV, TSV, JSON, plain text, Markdown and common image formats. Generated files appear as download cards in your chat after validation and security scanning.
Charts and data visualizations are supported. For AI-generated artwork, use Image Studio.
Availability, usage and file handling
Provider sandboxes require an eligible paid plan and available AI allowance. Free and anonymous users use MultipleChat’s standard tools. Sandbox usage counts toward your shared allowance; consumption varies with the model, task and tools used.
Eligible original files are sent to the provider running the sandbox. With ChatGPT + Claude sandbox, Anthropic receives the execution task and files, and OpenAI receives the results. With Claude + ChatGPT sandbox, OpenAI receives the execution task and files, and Anthropic receives the results.
Web search: unavailable while a provider sandbox is selected. Choose MultipleChat tools for web research.
AI Team: requests with newly attached files use the first selected model; text-only AI Team conversations retain team processing. Side by Side uses its existing tools.
Code execution helps the AI calculate and inspect results, but it does not guarantee that every answer is correct. Review important calculations and generated files before relying on them.
Provider sandboxes require an eligible paid plan and use your shared AI allowance. Web search is unavailable while a provider sandbox is selected.

FAQ
Questions people ask before trying it.
FAQ content helps real buyers and gives the page more long-tail topical coverage.
Can I use one AI model instead of collaboration?
Yes. You can chat with one model, compare several models side by side, or coordinate multiple models in a collaborative workflow.
What makes AI Collaboration different from comparison?
Comparison shows separate model answers. Collaboration assigns work across models and produces one synthesized answer with review signals.
Does MultipleChat support files and projects?
Yes. Projects keep conversations, uploaded files, and instructions together so models can work from the same context.
Do users get the latest AI models?
Yes. MultipleChat provides access to current AI model versions through API integrations with model providers, so users can work with the latest supported ChatGPT, Claude, Gemini, Grok and web-search models in one workspace.
Can I import existing chats into MultipleChat?
Yes. Users can import previous chats so old work does not stay trapped in another tool. Imported conversations can become part of the MultipleChat workspace and continue alongside projects, files and multi-model workflows.
I have my own ChatGPT API key. Can I integrate it with MultipleChat?
For self-serve plans, no. MultipleChat does not currently support bringing your own ChatGPT API key. Model access is provided through MultipleChat's managed API integrations so routing, collaboration workflows, verification, billing, safety limits and support stay consistent inside one workspace. Enterprise customers can discuss dedicated infrastructure or API-key ownership as part of a custom plan.
Why do Studios exist if I can already upload and edit documents in AI chat?
Yes, users can upload documents in chat and ask AI to read, summarize, rewrite, edit or improve them directly inside the conversation. Studios exist for the next level of document work. Technically, they are designed around larger document workflows, structured generation, formatting, exports, revision steps and file-specific handling instead of a normal chat turn. Product-wise, they give users a cleaner flow: create the document, revise sections, preserve structure, and export the result without fighting a chat box. That is why Document Studio, Presentation Studio and Data Studio can handle serious deliverables more reliably than a generic chat upload.
Is there a free way to start?
Yes. The public call to action highlights free daily messages and no credit card requirement.
