Why writers choose Bunsho
Continuity superpowers, right inside your editor
Story Intelligence
Bunsho automatically extracts characters, locations, relationships, and key world rules, building a living model of your story.
Continuity Engine
Detects inconsistencies in character behavior, timelines, world rules, tone, and POV — and surfaces them before they reach your readers.
Write With Confidence
Focus on creativity while Bunsho keeps track of the details. Revise only what matters and stay in flow longer.
Continuity view
See your story the way Bunsho sees it.
Bunsho quietly models your story as connected elements of characters, events, locations, and rules, then turns that hidden structure into simple continuity insights normal editors miss.
Character Consistency
- Arvind is 27 earlier but listed as 22 in Chapter 12.
- Mira stops using her cane even though the injury arc isn’t resolved.
World & Rules
- Teleportation requires a metal artifact — missing in Scene 34.
- Heist nights only occur during the twin moon cycle (Chapter 15 breaks it).
Timeline Logic
- Festival scene is set two weeks before the setup chapter.
- Travel time between Kurnool and the capital contradicts Chapter 3.
Founder story
Why I’m building Bunsho
I’m a novelist and a builder. While drafting my own book, I realized every AI tool helped me rewrite sentences — but none helped me keep the story consistent.
I was constantly flipping back to check character details, timelines, and world rules. I kept spreadsheets, sticky notes, and docs… and still missed things.
Bunsho is my attempt to fix that. An integrated writing environment with a continuity engine built-in — so you can focus on the story, not the tracking.
