Which AI note takers work with Claude and ChatGPT?

Short answer: several AI note takers now connect to Claude and ChatGPT. ChatGPT's app directory lists Granola, Fireflies, Circleback, Fathom, tl;dv, Read AI and Krisp, and Claude's connector directory lists the same tools plus Otter. Reline (reline.so) is listed in Claude's connector directory as a Community connector, and is not in ChatGPT's app directory yet: there it connects in developer mode through its MCP server at https://mcp.reline.so/mcp, which also works in Cursor, Claude Code, Gemini CLI and Windsurf.

Most people who use an AI assistant for meeting follow-up do the same thing: open the transcript, select all, paste it into a chat, ask for a summary. It works for one meeting. It stops working the moment the question spans three calls, or you want the assistant to create the follow-up note itself. MCP fixes that. This guide shows how to connect Reline to the assistants people actually use, what the connection can and cannot do, and which prompts are worth your time.

Directory listings checked on 2026-09-26. Reline was listed in Claude's connector directory on 2026-09-30. A listing gives you one-click setup; any tool with a remote MCP server can also be added by hand as a custom connector, which is how Reline connects to ChatGPT and the other clients today. The rest of this guide shows the setup for each assistant, and what the assistant can do once it is connected.

MCP stands for Model Context Protocol. It is an open standard that lets an AI assistant talk to an outside tool through a server. The assistant asks the server which tools it offers, the server checks who you are and what you may see, and every call is answered with your permissions, not the assistant's. Reline runs an MCP server at https://mcp.reline.so/mcp. Once connected, Claude, ChatGPT, Cursor and the others can search your notes, read transcripts and action items, and create notes, inside the workspaces you approve.

• Search across your notes and open the one it finds.
• Read a transcript with speaker separation, by time range or by speaker.
• List meetings, folders, people, calendar events and action items, and mark an action item done.
• Create notes and folders, and append to an existing note.
• Tell you how many notes match a filter, counted against what your account can actually see.

1. In Claude, open Customize, then Connectors, and search for Reline. It is listed as a Community connector.
2. Click Connect. Claude reminds you that Community connectors have not been reviewed in depth. On Team and Enterprise plans, an owner adds Reline for the organization first, then each member connects with their own account.
3. Sign in with your Reline account and pick the workspaces the assistant may reach.
4. Start a chat and ask about a meeting. Claude will show the Reline tools it is calling.

To add Reline by hand instead, choose Add custom connector under Customize, then Connectors, and paste https://mcp.reline.so/mcp as the server URL. Signing in and picking workspaces work the same way.

ChatGPT connects to remote MCP servers through developer mode on the web app. According to OpenAI's own help article, Business, Enterprise and Edu workspaces get full read and write access once an admin turns developer mode on, and Pro users can connect servers with read access. On Business and Enterprise plans the admin enables it under Workspace Settings, Permissions and Roles, Connected Data. Then create the app with the Reline server URL, scan tools, complete the sign-in, and publish it for your workspace.

The Reline settings page under Connectors shows the same snippets with a copy button, so you never have to retype the address.

• "What did we decide about pricing across the last three calls with Acme? Cite the notes."
• "List every open action item from this week's meetings, grouped by owner."
• "Read the transcript of yesterday's call with the client and draft a follow-up email in my voice."
• "Which meetings in the last month mentioned churn? Give me one line per meeting with a link."
• "Create a note called Q4 hiring plan in the Leadership folder with these five bullets."

Notice that every answer comes back with a link to the note. That is the habit to build: read the answer, open the note, and if a number or a promise matters, play the line. Reline keeps the audio with the note, so the check takes seconds.

Consent is per workspace and per connection. You choose which workspaces the assistant may reach when you connect. It sees exactly what your account sees, nothing more, so other members' private notes stay private. Every connection is listed in Reline under Settings, Connectors, and you can revoke one at any time. If you connect from two devices you get two connections, and revoking one leaves the other working.

• The assistant's answer is only as good as the transcript underneath it. A summary that names a number is a pointer, not a fact, until you have opened the note.
• Search works across notes and summaries. For a specific line, the assistant opens that note's transcript rather than searching every transcript at once.
• Long lists page. A short page does not mean the end, only a null cursor does. Good clients handle this for you.
• ChatGPT on mobile does not support custom MCP apps at the time of writing. Use the web app.
