Fixes typos on the space bar

thhe becomes the the instant you finish the word. A brief blue underline shows what moved; ← within 3 seconds undoes it.

Finishes your sentences

Pause and grey ghost text completes the sentence. Tab accepts it and offers the next one. Ctrl+Tab takes one word.

Learns how you write

Retype a word and the pair becomes an autocorrect entry. Undo a fix twice and the word joins your dictionary. Rules you keep undoing stop auto-applying.

Works everywhere

Mail, chat, browsers, editors, terminals. Built with Claude Code's prompt in mind.

Fast

About 120 ms from keystroke to suggestion on an NVIDIA GPU, with Gemma 3 1B. Runs on CPU with SmolLM2.

Insights

A tray flyout with today's numbers, and a dashboard with acceptance over time, latency, per-app stats, and what the model saw.

Everything stays on your computer.

No account, no cloud, no telemetry. The only network calls are the first-run downloads of the engine and the model.
