AI autocomplete that finishes your sentences wherever you type
Finish sentences inline in any text field across your browser, from email clients and docs to chat and CRM tools.
Produce full paragraphs, replies, or documents from a short prompt without leaving the page you are working on.
The engine learns how you write and suggests phrasing that sounds like you rather than generic AI output.
Works as a browser extension, so there is no new app to adopt and no per-tool setup for the sites you already use.

A storytelling toolkit that checks your grammar and coaches your craft
Around two dozen report types examine readability, sentence rhythm, pacing, passive voice, overused words, dialogue tags and more, with explanations for every flagged issue.
Analyse entire drafts rather than single documents, including chapter critique, plot analysis, character analysis and a virtual beta reader that simulates reader response.
Structured canvases help outline direction, characters and plot before you write the first chapter.
Writing sessions, sprints, creative nudges, placeholders and resets are designed to keep a long project moving past the initial burst of motivation.
