No AI, no credits

What it costs
Credits only for the AI drafts.
A query letter or a synopsis costs 2 credits and an author bio costs 1, after the chapter analysis they draw on. The free trial includes enough credits to try them, and a license comes with 300 starter credits. Everything else in Bookshaper works without credits.
The short version
Questions, answered.
How does the query letter and synopsis generator work?+
Bookshaper analyzes your manuscript chapter by chapter, then drafts a query letter and a synopsis from that analysis and your submission profile: genre, word count, comps and bio facts. You edit every draft before you send it.
What does it produce?+
A query letter of about 250 words with a variant per agent, a short pitch, a one-page synopsis of about 500 words, a two-page synopsis of about 1,000 words, and an author bio in short and long versions.
Does the synopsis include the ending?+
Yes. Both synopsis lengths reveal the ending, as agents expect. The query letter and pitch do not.
Is the generator free to try?+
Yes. The trial is free and includes enough credits to try the AI features: a query letter or a synopsis costs 2 credits, after the chapter analysis it drafts from.
Will it write my book?+
No. It drafts submission materials from a manuscript you have already written. It does not draft or edit your book.
Can I use my own AI API key?+
Yes. If you have your own key from a supported AI provider, Bookshaper can use it instead of credits.
How much does Bookshaper cost?+
$29.99 one-time at launch pricing, through December 31, 2026, for Windows, macOS and Linux on one license, with 300 starter credits.
Try it on your own manuscript.
7 days of actual use, not 7 calendar days. Buy once when you are ready; one license covers Windows, macOS, and Linux.
