Plans and pricing
When the trial ends you drop to Free automatically; to upgrade, open Settings → Plan → Upgrade to Pro. Checkout is handled by Paddle (our merchant of record), prices are shown with tax for your location, and invoices, payment method and cancellation live under Manage subscription. The subscription pays for an always-on knowledge base that any agent can read and write: hosting, import, bibliography, versions, OAuth connections, Zotero, usable from a phone browser; offline copies and backup mirrors are planned. Model costs are not included: you use your own API key and pay your provider directly; Settings and Stats show real tokens and an estimated cost per job (estimated with OpenRouter's price list; your provider's bill is authoritative). Cursor users need no key at all.
One "agent run" = one ingest, one chat reply, or one deep lint.
| Plan | Term and price | What you get |
|---|---|---|
| Pro trial | 14 days from sign-up, free, no card | Everything in Pro; unlimited agent runs; the first 10 runs on us (a cheaper model; content goes through the platform's OpenRouter account), no API key needed |
| Free | Free forever | 20 agent runs per month; 200 notes, 20 MB, 1 token, 7-day version history; bring your own key |
| Pro | USD 6 per month or 60 per year | Unlimited agent runs; 10,000 notes, 1 GB, 90-day version history; multiple tokens |
| Self-hosted | Free (AGPL-3.0) | docker compose brings up Postgres and the service, same code (built-in browser included); you supply the encryption key; Google sign-in, mail and the no-key trial are optional; plan limits are adjustable with environment variables |
Limits only block additions: at the note or storage limit you cannot add or grow pages, but reading, shrinking, archiving and export keep working and nothing is deleted or altered. Version snapshots are kept 7 days on Free and 90 days on Pro and during the trial; the latest version of every page is kept forever. The plan card in Settings shows current usage.
