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.

  5. Copy your favorite into KDP — edit every word before publishing.

Tips for fiction authors

  • Give Kestrel — Free concrete story material: who wants what, what stands in the way, and what they could lose — not just "a thrilling adventure."
  • Pick the genre readers would search under on Amazon, not the subgenre only your critique group knows.
  • Amazon allows up to 4,000 characters in the description field — aim for 150–350 words of tight, vivid copy.
  • Use the blurb builder first for structure, then this tool to polish tone for your genre.
  • Review both variants and merge the strongest lines. Neither draft should ship unedited to KDP.

Common questions
Is this really free?

Yes. Guests get several free generations per device via Kestrel — Free. Sign in to save drafts across devices.

How does genre trend awareness work?

Kestrel — Free receives guidance on emotional contract, trope appetite, and pacing patterns common in your selected genre — without copying any specific book.

Is my manuscript uploaded?

No. Only your title, genre, and short pitch are sent for description generation. Cover images stay in your browser unless you download the resized JPEG.

Why two descriptions?

Hook-first opens on tension or situation; character-first opens on voice or longing. Having both helps you find the right energy faster.

Will the copy sound AI-generated?

The tool avoids corny phrases and keyword stuffing, but you should still edit the result to match your voice before publishing on KDP.
