Powerful Plugins

Blurb Doctor

Your blurb is what's killing your sales. Blurb Doctor diagnoses what's wrong, then rewrites it into back-cover copy that turns browsers into buyers, with the keywords, warnings, and tagline a bestseller needs.

Diagnose your blurb. Cure your sales.

Blurb Doctor is a Claude Cowork plugin that writes and sharpens your book's blurb, the few sentences that sell your book before anyone reads a word, so a casual scroller becomes a paying reader.

Most authors lose sales not because the book is weak, but because the blurb is.

Blurb Doctor fixes that in minutes, then builds the rest of the package: a tagline, a comp line, your Amazon keywords and categories, and ready-to-paste versions for Amazon, BookBub, ads, and BookTok.

Instant download, lifetime use, and free updates. No tech skills needed.

Questions, answered

What is wrong with my current blurb?

Most blurbs summarize instead of selling. Blurb Doctor turns yours into a hook with stakes and a promise.

Does it work for any genre?

Yes. It matches the conventions of your specific genre.

Can I use it on a book that is already live?

Absolutely, and you can update your Amazon blurb anytime to test the new one.

Is it just a summary generator?

No. It writes persuasive sales copy designed to convert browsers into buyers.

Do I need anything special to run it?

Just Claude Cowork on a Claude Pro or higher plan. The backlist scan and Beat the Shelf also use the free Claude in Chrome extension, which is what lets them read live Amazon pages. Everything else runs right in the chat.
