Most of the big ones do. ChatGPT, Claude, Gemini, Mistral, Copilot and Grok all let you create projects, which keep related chats, files and instructions together in one place. You create each project yourself in the tool's projects section, then add the files and instructions you want it to use.
- In ChatGPT, open Projects, then the three dots, then project settings.

Is there a limit on how much text I can paste into an AI Chatbot?
Yes, and it depends on the tool. Gemini accepts very long text and is close to unlimited for most everyday use, while Claude has a much stricter limit. If you run out of space, put the text into a Word document and upload it as a file instead of pasting it into the chat.
Is Perplexity Good for Translation?
Yes, very much, especially with its own Sonar models. Perplexity is an aggregator, so on the Pro plan you can switch between models such as GPT, Claude and Gemini underneath it. Check which model is switched on before you judge the result, because the translation quality depends on that model.
Is Perplexity Finance any Good?
Yes. Perplexity Finance tracks markets, crypto and company financials, with charts, balance sheets and history, and it answers with sources. Open it at perplexity.ai/finance, or type a company name or ticker followed by the word stock, for example NVDA stock. On the mobile app, type finance in the search bar.
