Planning tools and long-form structure

Novels fail when structure is improvised scene by scene. Beat sheets, chapter planners, and blurb builders help you decide pacing and reader promises before you spend tokens on prose. Pair these tools with an outline in Entangled Text so generation follows a spine.

How to use it

  1. Enter genre and tone — cozy mystery, dark romance, epic fantasy, etc.
  2. Paste your premise — protagonist, conflict, and setting in a few sentences.

  4. Check Amazon search and trademark links on your favorites.

Tips for fiction authors

  • Short main title plus keyword-rich subtitle is a common KDP pattern — but avoid keyword stuffing that Amazon may reject.
  • Say titles aloud. If you stumble, readers will too — and audiobook listeners will hear every awkward syllable.
  • Use the title length checker to preview mobile search truncation before committing to metadata.
  • Comps in your premise help Kestrel — Free suggest titles that signal genre without copying existing bestsellers.
  • Run trademark search on every finalist. Similar titles in your genre can still create confusion or legal risk.
