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.

Tips for fiction authors

Keep your main title short and memorable — under 50 characters is ideal. Use the subtitle for searchable keywords readers actually type.
Amazon can reject titles with excessive punctuation, all caps, or promotional language like "bestseller" or "award-winning."
Series titles should follow a consistent format: "Series Name Book 1: Individual Title" helps readers find the next installment.
Test your title at small sizes. It must be legible as a thumbnail on Amazon search results — the preview shows roughly mobile truncation.
After the AI book title generator suggests options, paste each here to check KDP length limits before committing.

Common questions

How many characters can a KDP title and subtitle be?

Amazon KDP allows 200 characters for the title and a separate 200 for the subtitle. Spaces and punctuation count. This page is the character counter for both fields.

Should I stuff keywords in my title?

Amazon policies discourage keyword-stuffed titles. Keep subtitles searchable but readable — not a comma-separated keyword list.

Does punctuation count toward the limit?

Yes. Every character including spaces and punctuation counts toward the 200-character cap.

How does the search preview work?

It shows roughly how much of your title and subtitle may appear in Amazon mobile search — about 42 characters of combined display.

Is my title uploaded?

No. The title length checker runs entirely in your browser on Entangled Text.

Is this a book title checker and Amazon character counter?

Yes. Paste a title and subtitle and it counts every character against the 200-character KDP limits, flags a field that runs over, and previews roughly how much shows in Amazon mobile search.
