Assistant remembers your entire manuscript instead of resetting each session like ChatGPT

Edits match your voice based on chapters you've already written
Never locked in—export DOCX, PDF, or EPUB on any plan, anytime
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
