Your readers will find every plot hole. Beat them to it.

Typewriter's continuity checker reads every chapter, every scene, and your entire story bible in a single pass. It builds a graph of facts: who said what, where things happened, what rules your world follows, and when events occurred.

Then it checks every fact against every other fact. Chapter 4 says the tavern is on Bridge Street. Chapter 19 says it's on Market Square. The checker flags it with both references. You decide which is correct.

Physical contradictions: eye color changes, scars that disappear, objects in the wrong place. Timeline errors: events that can't happen in the stated order, characters in two places on the same day, seasons that don't match the month.

Unresolved threads: a letter mentioned in chapter 4 that's never explained. A character who enters a scene and never leaves it. A promise made that's never kept or broken. Knowledge violations: a character reacting to information they shouldn't have yet. World rule breaks: magic used in a way that contradicts your established system.

The continuity checker doesn't just scan prose. It cross-references your story bible entries. If your story bible says Elara is 28 years old and your manuscript says she graduated college "twelve years ago," that's flagged. If your worldbuilding says teleportation requires line of sight and chapter 14 has someone teleporting to an unseen location, that's flagged.

The story bible is your source of truth. The checker enforces it across 80,000 words so you don't have to.

Each flag shows the exact passages involved with chapter and paragraph references. Click to jump to either location in the editor. Three actions: fix it now, dismiss as intentional, or mark for later revision.

Dismissed flags don't come back. Marked-for-later flags appear in your revision queue. The checker learns what you consider an error versus a deliberate choice. Run it after every major revision to catch what your edits introduced.
