What you get with Bulk Publishing Books
Research tells you what to write. Bulk Publishing Books then writes it, edits it, designs the cover, formats the files and fills in your KDP listing. You upload and press publish.
Research that feeds the book
The keywords, categories and competitor gaps you pick are handed to the blueprint. You do not copy findings into a separate writing tool.
A Persona writes it
Each book is written in a saved Persona voice, then an editorial pass flags factual risk, repetition, voice drift and AI tells before you approve.
Formatted and covered
You get an interior PDF at a KDP trim size, an EPUB 3 file and a full-wrap cover PDF from one of three cover directions.
Metadata in KDP order
Title, description, 7 keyword slots, 3 categories and the AI disclosure are laid out in the order KDP asks for them, each with a copy button.
Tracked after launch
Published books get daily BSR, price, review and keyword rank snapshots, a launch checklist and series suggestions.
Your first book is on us for 7 days
Research, manuscript, cover and listing. Keep it even if you cancel.
Which should you pick?
Written books
Non-fiction, workbooks and fiction written in a Persona voice with an editorial pass.

FAQ
How much is Book Bolt?
Its September 2026 homepage lists Pro at $23.99 a month or $19.99 a month billed yearly, and Premium at $35.99 or $29.99. We could not load the live pricing page, so check before you buy.
Does Book Bolt refund?
Its pricing FAQ says that, because of the 3-day trial, it does not provide refunds.
How much does Bulk Publishing Books cost?
Bulk Publishing Books is $169 a month and includes 8 complete books (Chains) a month, unlimited research and unlimited Personas. A Chain counts when you approve its blueprint.
Is there a free trial or a refund?
There is a 7-day trial that needs a card through Stripe. Cancel before day 7 and you are not charged. During the trial research covers a set of starter keywords and categories. We do not offer refunds after billing starts, because every book uses real AI compute.
Do I need my own AI keys?
No. AI usage is included in the plan.
Does Bulk Publishing Books upload to KDP for me?
No. Amazon does not offer a public upload API for KDP, so you upload the files and paste the metadata yourself. Bulk Publishing Books gives you every file and field in the order KDP asks for them.
