Gotchas
- 3 teammates per workspace
Free plan allows a workspace of up to 3 members and 3 invitees; larger teams require a paid Prime or Enterprise plan.
- Recent 10 versions only
Version history is limited to the most recent 10 versions per note; unlimited versions require Prime.
- Trash purged after 3 days
Deleted notes remain in the trash can for only 3 days (vs 30 days on paid plans) before permanent deletion.
- 1MB max per image
Uploaded images are capped at 1MB each on the free plan; Prime raises this to 20MB per image.
- 20 GitHub pushes/month
Free plan limits pushing notes to GitHub to 20 times per month.
- 2,000 API calls/month
API usage is capped at 2,000 calls per month on the free plan (Prime allows 20,000).

Full-text search across notes is a Prime-only feature; the free plan lacks it.

Rendered PDF export is unavailable on the free plan and requires Prime.
- 3 custom templates max
