One knowledge base for ChatGPT and Claude

ChatGPT Projects and Claude Projects each keep their own files. Gistr keeps your videos, PDFs, articles and notes in one place, and both assistants can search it.

Your files are split across projects

Files stay in one project

A PDF you uploaded to a ChatGPT project is not in your Claude project. You upload the same files again and again.

Videos and links do not fit

Projects take files. The lectures, podcasts and articles you learn from have no place to live next to them.

Every chat starts from zero

Switch assistants or start a new chat and the context is gone. You explain your topic and paste your sources again.

A library your assistants can use

Search your whole library

Search your whole library

Both assistants search your threads, collections and notes. Ask a question and get answers from what you saved, not from the open web.

Frequently asked questions

Projects keep files inside one assistant. Gistr is one library that works in both, and it holds YouTube videos, podcasts and web pages as well as files. Your notes and highlights stay with each source.

YouTube videos, podcast episodes, PDFs, Word and PowerPoint files, EPUBs, web pages, audio files and your own notes. Group them into collections by subject or project.

Yes. Connect Gistr to each assistant once. Both see the same library, so a source you save in one chat is ready in the other.

MCP (Model Context Protocol) is the open standard that ChatGPT, Claude and other AI assistants use to connect to apps. The Gistr MCP server lets your assistant search, read and add to your Gistr notebook while you chat.

Claude (web, desktop and mobile), ChatGPT with Developer mode, Claude Code, Cursor, VS Code and any other app that supports remote MCP servers with sign-in.

Yes. The assistant only sees your notebook after you approve access with your Gistr account. You can see and disconnect connected apps at any time in Gistr under Settings → MCP.

Connecting is free. Reading and saving notes is free. AI features that Gistr runs for you, like making a presentation, use AI credits from your Gistr plan, the same as inside Gistr.
