About this tool

This page writes title ideas, not the store description — for that, use the book description generator (/tools/ai-kindle-description-generator), or the blurb builder for a no-AI template. Describe your premise and genre, and you get eight title and subtitle options with an Amazon search preview, a KDP length badge, and a trademark-search link. Check trademarks and Amazon listings yourself before you commit.

What you can do

  • Eight distinct title and subtitle combinations per generation
  • Amazon mobile search preview — roughly 42 characters of display
  • KDP length badges flagging options near the 200-character limit
  • One-click trademark search links on each title card
  • Genre and tone inputs for market-appropriate suggestions
  • Pairs with title length checker for final metadata validation
  • Kestrel — Free with several generations per connection

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.
  3. Click Generate titles and review eight options with search previews.
  4. Check Amazon search and trademark links on your favorites.
  5. Paste your chosen title into the title length checker before KDP upload.

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.

Common questions
Is this a book description generator?

No. It suggests titles and subtitles. For the Amazon product description, use the book description generator at /tools/ai-kindle-description-generator, which drafts two genre-aware versions from your title and pitch. The blurb builder at /tools/blurb-builder is the no-AI template version.

Are these titles trademark-checked?

No. Use the trademark search links on each card, then verify Amazon listings and official trademark databases yourself.

What does the search preview show?

About 42 characters — roughly how much of your title plus subtitle Amazon may show on mobile search results.

Is this free?

Yes. Kestrel — Free provides several title generations per connection. Sign in to save favorites.

Will Kestrel — Free copy existing book titles?

It aims for original combinations from your premise. Always verify Amazon and trademark databases before publishing.

Is my premise uploaded permanently?

Your premise is sent for generation only. Sign in to save tool drafts to your account if you want to revisit options.

How do I come up with a book title?

Start from what the reader is promised — the genre, the conflict, the feeling — rather than from the plot. Generate a batch, keep the two or three that fit the cover and the genre shelf, check that they read well at about 42 characters in Amazon mobile search, then search Amazon and trademark databases for clashes.

Can it suggest a subtitle for a series?

Yes. Each idea can carry a subtitle, and you can ask for a series line such as "Book One of the Ash Crown". The KDP length badge shows when title plus subtitle runs long.
