Plot Hole & Continuity Checker
The longer the story, the more small facts drift. This checker lists conflicting ages, hair and eye colors, dialogue after a character's death and name spelling variants, quoting each spot.
What you can do next
Save to a private draft in the Studio (login needed; first-timers get a 7-day free trial).
In a saved work you can run Story Tests (foreshadowing, timeline, voice and continuity checks) and Story Refactoring.
How to use it
- Paste your manuscript.
- Press “Check” to see candidate contradictions with quotes, chapters and line numbers.
- Read each one: some are intentional (flashbacks, ghosts, a character growing older).
FAQ
What does it look at?
Sentences like “Mina was 17” or “Mina's black hair”, dialogue after “Mina died”, and names that differ by one letter (Katherine / Catherine).
Will it flag things that are fine?
Sometimes — a birthday, a flashback or a dyed hair scene can be intentional. Treat results as candidates.
Is my manuscript uploaded?
