River Writer is a free Mac app for screenplays, stage plays and novels. You write plain text (.fountain ormd) and a live preview shows the formatted, print-ready pages beside it: Screenplay, Multi-cam, Stage Play or Manuscript.

No accounts, cloud, telemetry or AI; it makes no network connections. Open source (MIT).

Ancher is an AI knowledge workspace that turns everything you read, watch, and save into work you can actually use. Capture articles, videos, PDFs, posts, and ideas without organizing folders.

Willow Knowledge lets you bring your writing style and personal context into Willow from ChatGPT, Claude, Gemini, or any AI you use. It's like giving superpowers to Willow Scribe. From now on, your email, slack msg, prompt, or wherever you write will sound exactly like you when you dictate.
Translate, shorten, fix or rewrite any text right where your cursor is — in any app on Mac. Dictate there too. No tabs, no copy-paste. Select text, hit a hotkey, and it's replaced in place. Or press ⌥` and speak in one language, get clean text in another. 13 languages. Privacy: Jarq uses cloud AI models to process your text and voice. Jarq itself doesn't keep your text on its servers, and your history stays on your Mac. Free: 5 actions a day. Pro: $4.99/mo or $39/yr. 14-day Pro trial, no card.
Create and update your knowledge base from Claude, Codex, or any compatible MCP client. Ask DocsAlot to add a page, fix an error, or improve your help center. It finds the relevant content, makes changes, creates a new version, and publishes, all from your existing workflow. See what questions users ask in your help center, discover what’s missing, and use those insights to improve your docs and decide what to build next.
A dedicated home for all your documentation, from internal knowledge bases, runbooks and onboarding guides to public docs. Keep projects open side by side across organizations and pick up where you left off. An agent works alongside you on the page you’re editing, while local files let you write offline and sync when you reconnect. Tabs, split views, and persistent sessions help you move between projects without losing context.

Reading, search and export always stay free.
