CommonplaceForge

A commonplace book you actually own.

A commonplace book that stays yours: keep an idea only in your own words, link ideas with a because, and export it all as plain text you keep forever. No account, no feed.

Keep your first idea →

How it works

  1. Keep by restating. Read a durable idea and its field; keep it by saying it in your own words.
  2. Connect. Link two ideas with a because — the reason they belong together.
  3. Come back. Kept ideas return for spaced review — no streak, no due-count dread.
  4. Synthesise. Gather three or more and write one paragraph tying them together — you write it, not the app.
  5. Own it. Export the whole book as plain text, and re-import it anywhere. Your gems are files.

On-device; no account; nothing leaves this device. No timer, no score to chase.
