Bunsho

Bunsho is a manuscript editor built for novelists who care about story logic as much as prose. Instead of asking you to fill in character sheets, it reads its story model directly out of what you write: every character, place, object and rule you commit to the page is remembered. When you ask for a check, it reads the chapter against everything the book has already established and reports only what contradicts it, quoting both passages in your own words with exact chapter coordinates.

That evidence-first approach is deliberate. Bunsho does not score your writing or grade your chapters; it reports facts and leaves the judgement to you. Each finding shows what the story has established about that character, object or timeline, so you can decide whether to resolve or dismiss it. A separate change-impact view maps the ripple of a single fix across scenes, lines and callbacks, so corrections do not quietly break something two chapters later.

Director Mode handles the moments when you are stuck. You @-tag characters in your cast, describe what should happen next, and Bunsho proposes a beat sheet. A preflight pass checks the plan against what each character already knows, so contradictions surface on the plan rather than in finished sentences. Rendered prose sits on the page it would join, with Accept, Re-render and Discard in reach. Editing is never metered, and the manuscript stays on your machine - pages are only sent for analysis when you deliberately run a check, and they are not stored or used for training.
