May 5, 2026 Connect Cosmonote to ChatGPT cosmonote.ai

You can now access your Cosmonote notes directly from ChatGPT. Ask ChatGPT to summarize your meetings, find action items, or search through your notes — all without leaving the conversation.

What you’ll need

  • Cosmonote account with at least one recorded note
  • Cosmonote API key (found in the app settings)
  • ChatGPT Plus, Pro, or Team account

Step 1: Enable Developer Mode in ChatGPT

  1. Go to chatgpt.com
  2. Open Settings
  3. Navigate to Apps & Connectors
  4. Under Advanced settings, toggle on Developer Mode

Step 2: Copy your API key from Cosmonote

  1. Open the Cosmonote app
  2. Go to the Settings tab
  3. Open the API keys menu
  4. Copy your API key

Keep this key handy — you’ll need it in the next step.

Step 3: Add Cosmonote as a connector

  1. In ChatGPT, go to Settings → Apps & Connectors
  2. Click Create
  3. Fill in:
    • Name: Cosmonote
    • Description: Access my Cosmonote audio notes, transcriptions, summaries, and action items
    • URL: https://nebula.cosmonote.ai/mcp
  4. Set authentication to OAuth
  5. Confirm by selecting I trust this application
  6. Click Create
  7. ChatGPT will redirect you to a Cosmonote authorization page
  8. Paste your API key and click Connect

That’s it. ChatGPT now has access to your notes.

What you can do

Once connected, you can ask ChatGPT things like:

  • “What were the action items from my last meeting?”
  • “Summarize my notes from this week”
  • “What did we decide about the project timeline?”
  • “List all my recent notes”

ChatGPT will use three tools to access your data:

  • list_notes — Browse all your notes with titles, dates, and summaries
  • get_note — Read the full content of a specific note (transcript, summary, decisions)
  • list_action_items — See action items extracted from your meetings

Privacy

ChatGPT only accesses your notes when you explicitly ask it to in a conversation. Your API key is stored securely by ChatGPT and is never shared. You can revoke access at any time by deleting the API key in the Cosmonote app.
