River Writer is a free Mac app for screenplays, stage plays and novels. You write plain text (.fountain or .md) and a live preview shows the formatted, print-ready pages beside it: Screenplay, Multi-cam, Stage Play or Manuscript. Git versioning is built in, so you can commit drafts, restore files and try an alternate ending on a branch. Outline, scratchpad and todos live as plain files in your project. No accounts, cloud, telemetry or AI; it makes no network connections. Open source (MIT).

Thinker blends whiteboards, kanbans, and docs into one clean, real-time space. Built for solo scribblers to fast-moving teams. Brainstorm, plan, write—live. No setup, no bloat. Free beta. 50 slots only. One free month after launch.

Thinker offers three essential features: A Kanban Board to Track your Todos, A Feature-rich Whiteboard, and a scratch pad. You can create projects within Thinker with each project having these three features attached with them.
