granola-sync

Granola is an AI meeting assistant that records, transcribes, and summarizes meetings. It stores all your notes in its own app — but doesn't offer a way to export or back them up automatically.

This tool syncs your Granola meeting notes to Google Drive as plain Markdown files, so they're searchable, portable, and yours. It runs as a lightweight Docker container on a server and re-syncs on a configurable interval.

File structure

Notes are saved as FolderName/YYYY/MM/YYYY-MM-DD_Title.md inside the configured Drive folder. Notes without a Granola folder go to Unclassified/.

.index.json

A hidden file stored in the root of your Drive folder. It maps each Granola note ID to its file path and last-updated timestamp. This is how the tool knows:

• which notes are already synced (skip)
• which notes have been updated (re-upload)
• where the old file is when a note gets renamed or moved (delete old, create new)

Do not delete .index.json. If it's lost, the tool loses all state — it will re-upload all 268+ notes as duplicates alongside any existing files.

Setup

1. Granola API key

1. Open the Granola app → Settings → Integrations → API
2. Generate a new API key
3. Copy it into .env as GRANOLA_API_KEY

3. Google Cloud credentials

1. Go to Google Cloud Console → APIs & Services → Enable APIs → enable Google Drive API
2. Credentials → Create Credentials → OAuth 2.0 Client ID → Desktop app — download the JSON
3. Copy client_id and client_secret into .env

4. Get a refresh token (one-time, run locally)

go build -o granola-sync .
export $(grep -v '^#' .env | xargs)
./granola-sync auth

A browser window will open. After authorizing, copy the printed GOOGLE_REFRESH_TOKEN into .env.

5. Configure .env

GRANOLA_API_KEY=grn_...

GOOGLE_CLIENT_ID=...
GOOGLE_CLIENT_SECRET=...
GOOGLE_REFRESH_TOKEN=...

# ID from the Drive folder URL
GOOGLE_DRIVE_FOLDER_ID=...

# Sync interval (e.g. 1h, 30m, 6h)
SYNC_INTERVAL=1h

GOOGLE_DRIVE_FOLDER_ID is the last segment of the folder URL:

https://drive.google.com/drive/folders/<FOLDER_ID>

Note: The Docker image is built for linux/amd64 only.

6. Run

cp .env.example .env  # fill in your values
docker compose pull
docker compose up -d
docker compose logs -f
