| 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
| - Designed specifically for Substack writers with formulas trained on viral patterns
- Two-stage TYPE-FORMULA process instead of generic AI summarization
- Knowledge Bank compounds over time as more articles are processed
- From URL to scheduled post in minutes with no copy-paste needed
- Credits never expire at your own publishing pace
