| 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
| - Finished, publishable files not drafts in one studio session
- All output is real—no mockups shown
- Line-edited writing that reads like a human wrote it
- No credits or subscriptions needed to write
- AI disclosure and copyright flexibility for Amazon publishing
