Mar 17, 2026 Use Cosmonote in ChatGPT cosmonote.ai

You already use ChatGPT to draft emails, summarize documents, or brainstorm ideas. What if you could also ask it questions about your meetings, lectures, or voice notes?

That’s exactly what the Cosmonote GPT enables. Type @cosmonote in ChatGPT, and you get access to all your notes. No need to open the app, search for the right note, or copy-paste content. Ask your question, get your answer.

How it works

In any ChatGPT conversation, type @cosmonote. ChatGPT will prompt you to activate the GPT. Once connected to your Cosmonote account, you can query your notes using natural language.

A few examples of what you can ask:

  • “What did we decide about the budget in Monday’s meeting?”
  • “What action items do I have this week?”
  • “Summarize my last voice note”
  • “What did Sarah say about the timeline?”

ChatGPT searches through your notes and answers directly.

Why it’s useful

You probably have dozens of accumulated notes. Meetings, lectures, ideas dictated while walking. Finding a specific piece of information means opening the app, searching for the right note, scanning through it.

With the GPT, you ask your question like you would ask a colleague who attended all your meetings. “What was the name of that vendor we discussed?” And you get your answer in seconds.

Practical use cases

Preparing a follow-up meeting. You have a follow-up with a client. You ask the GPT: “Summarize my last 3 meetings with this client and list open items.” You show up prepared without re-reading all your notes.

Finding a decision. Someone asks why a certain decision was made. You ask: “What did we decide about X and why?” You get the context and reasoning.

Reviewing your action items. At the end of the day, you ask: “What action items do I have from this week’s meetings?” You get your todo list without effort.

Studying for a course. You recorded a lecture or training session. You ask: “Explain the concept of X that the professor mentioned.” You review by asking questions.

How to activate the GPT

  1. Open ChatGPT (on chat.openai.com or the app)
  2. In a conversation, type @cosmonote
  3. Click on the Cosmonote GPT when it appears
  4. Connect your Cosmonote account (just once)
  5. Ask your first question

You need a ChatGPT Plus account to use GPTs. If you’re on the free plan, you can still use the “Ask AI” feature directly in the Cosmonote app.

Your notes stay private

The GPT only accesses your notes when you invoke it. It doesn’t store anything or train on your data. You decide when to ask it a question. And your notes remain hosted in France, on Cosmonote servers.
