Your manuscript never leaves the machine.
Grammarly, Notion AI, and ChatGPT send every sentence you touch to the cloud, where it is logged. Typilot runs every rewrite and summary against a local model - unpublished work stays unpublished, and there is no vendor copy of your draft.
Polish that matches your voice.
Define a custom rewrite prompt once - dry, lyrical, punchy, house style - and reuse it from a keystroke. Because each command only sees the selected passage, the model never ingests the whole document.
Works inside the tool you already write in.
Scrivener, Google Docs, Ulysses, Obsidian, iA Writer, the browser - Typilot acts on whatever text field has focus. No per-app plugin, no copy-paste into a separate chat window.
Pay once instead of renting your editor.
Grammarly Premium runs about $144 a year, every year. Typilot is a one-time $199 lifetime license (or $7.99/month if you prefer), and it keeps working offline - on a plane, in a cabin, mid-deadline with no wifi.
