Granola Transcript Exporter

Export all your Granola.app meeting transcripts to markdown files.

How it works

1. Reads your Cognito auth token from Granola's local storage
2. Auto-refreshes the token if expired
3. Uses local cache for recent transcripts
4. Fetches older transcripts from Granola's API
5. Saves each meeting as a markdown file

Requirements

• macOS with Granola.app installed and logged in
• Python 3.7+

Usage

python3 extract.py

Output: ~/transcripts/YYYY-MM-DD_Meeting Title.md

Configuration

X-Client-Version

The script requires the X-Client-Version header to match your installed Granola version.

To find your version:

1. Open Granola
2. Click the menu bar icon
3. Click "About Granola"

If you get "Unsupported client" errors, update CLIENT_VERSION in the script to match your version.

Output format

# Meeting Title

How it was reverse engineered

1. Found auth tokens in ~/Library/Application Support/Granola/supabase.json
2. Extracted Electron app bundle (npx asar extract) to find API endpoints
3. Discovered required X-Client-Version header from app source
4. Implemented Cognito token refresh for long-running exports
