What makes it different
  • All writing and organization features work without AI; AI is optional
  • AI operates on your notes and sources, not a blank prompt, keeping context across sessions
  • Text never used to train AI models; all writing remains private
  • Every AI result appears as a suggestion beside the draft; nothing rewrites in place without approval
  • One project holds multiple chapters with notes and sources; suitable for book-length manuscripts
  • Finishes sentences from your actual work history and connected files, not generic AI
  • Shows source for every suggestion so you can verify it before accepting
  • Catches mistakes and contradictions between what you're writing and your work history
  • Works inline in the apps you already use without installation
  • You stay the author with full control over what gets written
