As a long-form writer, I kept hitting the same wall: one model writes a great chapter, then the book falls apart by chapter forty. Characters drift, planted clues never pay off, the voice slides. So I built Wenmai around a simple idea — split writing from checking. Four AI roles, one job each: canon (a fact ledger), draft, continuity check, character voice, and a final review from a different model. You bring your own API key (BYOK) and pay your provider's price — Wenmai never resells tokens. The Draft role is free and unlimited, so you can finish a whole book before paying anything. $6/mo unlocks the cross-review roles. Would love feedback from anyone who's written more than thirty chapters. Happy to answer questions in the comments!
