About this tool

Chapter endings sell the next page — especially on Kindle Unlimited where one weak close loses the reader to another book. This chapter ending hook checker scores the last roughly 120 words of each detected chapter for open questions, concrete images, and avoidance of summary wind-downs. Paste a multi-chapter manuscript with Chapter headings; scoring runs in your browser.

What you can do

  • Per-chapter scores for the final ~120 words of each detected chapter
  • Checks for open questions and unresolved tension at chapter breaks
  • Flags summary wind-downs and "and then they slept" endings
  • Concrete image detection — strong closes often end on a sensory beat
  • Requires Chapter headings for multi-chapter analysis
  • Works on novels, serial fiction, and Story Studio chapter exports
  • Private browser analysis — no manuscript upload

Why manuscript analysis matters for fiction

Rule-based analyzers catch patterns human eyes skim past—especially in AI drafts where filter words, adverbs, and passive voice cluster predictably. Use metrics to prioritize revision, not to flatten your voice. Run a chapter first, fix the worst offenders, then scan the full manuscript.

How to use it

  1. Paste a multi-chapter manuscript with Chapter 1, Chapter 2 style headings.
  2. Click Analyze to score each chapter ending.
  3. Review weak endings first — often the ones that summarize instead of hook.
  4. Revise final paragraphs to end on tension, image, or question.
  5. Re-run after edits to confirm ending scores improved.

Tips for fiction authors

  • End on a decision, revelation, or danger — not on characters going to sleep unless sleep is the threat.
  • Serial and KU fiction benefits from micro-cliffhangers every chapter; standalone literary may prefer quieter closes.
  • AI chapter endings often summarize what happened. Cut the recap and land on the next unanswered beat.
  • Compare your strongest and weakest chapter endings — rewrite weak ones to match the energy of your best.
  • Pair with the opening hook checker: first lines sell the sample, last lines sell the next chapter.

Common questions
What if my book has no chapter headings?

The tool treats the whole paste as one chapter. Add "Chapter 1" style headings for per-chapter scores.

Does every chapter need a cliffhanger?

No. The tool flags summary wind-downs and weak tension — a quiet image can score well if it provokes curiosity.

Is my manuscript uploaded?

No. Chapter ending analysis runs entirely in your browser on Entangled Text.

Why do AI drafts end chapters weakly?

Models often close with summary or emotional recap. This checker marks where to end on forward momentum instead.

Does this help KDP and Kindle Unlimited?

Yes. Strong chapter endings improve read-through — readers who finish chapter one are more likely to buy or continue.
