About this tool

AI drafts often introduce name variants — Jon in chapter one, John in chapter ten. This character name variant detector groups similar capitalized names with occurrence counts so you can fix typos or confirm intentional name differences.

Continuity checks across long manuscripts

Series bibles, name-variant lists, and POV slip detectors address the main failure mode of AI long-form writing: drift. Names change spelling, timelines compress, and point of view wobbles. Log facts as you write and re-scan after every major revision pass.

How to use it

  1. Paste your full manuscript or chapters.
  2. Click Analyze to extract capitalized names.
  3. Review grouped similar name pairs.
  4. Search your draft to confirm typos vs different characters.
  5. Standardize spelling in your master character list.

Tips for fiction authors

  • Run this on your complete manuscript, not individual chapters. Name variants often appear when AI regenerates a chapter without full context.
  • Characters with similar names confuse readers even when spelled consistently. If your scanner groups them, consider renaming.
  • Check for inconsistent capitalization: "the Dark Forest" vs "the dark forest." Proper nouns in your world need a style guide.
  • Export your name list and share it with beta readers. They can flag variants you have become blind to.

Common questions

How does it detect similar names?

It compares capitalized name tokens for edit-distance similarity and groups likely variants.

Will it flag different characters with similar names?

Sometimes. Use counts and context — twins named Jon and John may be intentional.

Does it catch lowercase typos?

It focuses on capitalized proper names. Use manuscript diff for broader typo checks.
