lantern-granola-sync

Sync your Granola meeting notes to your Lantern library.

Usage

npx lantern-granola-sync

On first run, it will:

1. Check for Granola credentials on your machine
2. Open your browser to authenticate with Lantern
3. Fetch all your Granola meeting notes
4. Create a "Granola" collection (if it doesn't exist)
5. Sync notes to your Lantern library and add them to the collection

Requirements

• Node.js 18+
• Granola desktop app installed and signed in (macOS only)
• Lantern account

How it works

The tool reads your Granola authentication from ~/Library/Application Support/Granola/supabase.json (automatically created when you sign into Granola).

Meeting notes are synced as conversations with:

• source: "granola"
• conversationType: "meeting"
• Automatically added to a "Granola" collection

Notes are tracked locally to avoid duplicates on subsequent runs.

Options

--force, -f          Re-sync all notes, even if already synced
--lantern-url <url>  Lantern web URL (default: https://onlantern.com)
--api-url <url>      Lantern API URL (default: https://api.onlantern.com)
--help, -h           Show help

Re-syncing

By default, notes that have already been synced are skipped. To force a full re-sync:

npx lantern-granola-sync --force

Data storage

Sync state and credentials are stored in ~/.lantern-granola-sync/:

• credentials.json - Lantern authentication
• state.json - Tracks which notes have been synced

To reset, delete this directory:

rm -rf ~/.lantern-granola-sync
