Powerful Plugins

Blurb Doctor

Your blurb is what's costing you sales, not your book. Blurb Doctor diagnoses what's wrong, rewrites it into back-cover copy that turns browsers into buyers, then scores it against the books winning your category right now.

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, content flags, and ready-to-paste versions for Amazon, ads, BookTok, and your newsletter. It all lands in one tidy Word doc, right in your chat.

Six tools, one plugin. Start a blurb from your manuscript, fix one you already have, repair your entire backlist, keep a series consistent, or benchmark yourself against the live top 10 in your subcategory.

Six tools in one plugin

Write from your book /blurb-from-book

Feed it your manuscript, an outline, or a one-line premise. You get three blurbs from different angles at your genre's ideal length, each with an ad-ready cut, scored on the 12-point Browse-to-Buy System and cleaned by the Red Pen Pass. Heat and darkness are read straight from your manuscript.

Fix the blurb you have /blurb-doctor

Paste your current blurb and get a 12-point score, a plain report on its weakest spots, and a rewrite that sells, plus paste-ready cuts for Amazon, ads, BookTok, and your newsletter.

Beat the Shelf /blurb-shelf

Scores your blurb against the live top 10 of your exact Amazon subcategory, pulled fresh. You see your percentile ("you'd beat 8 of the top 10") and exactly what the winners do that yours doesn't.

Repair your whole backlist /blurb-backlist

Pull every book by Amazon scan, a CSV, or a folder of text files. You get a prioritized health report, a rewrite for every underperformer, and a revenue-ranked fix list. It handles catalogs of 50+ books.

Keep a series consistent /blurb-series

Builds, extends, or audits a series. It locks heat and tone across every book and produces a harmonized blurb set plus cross-promo hooks.

Set it once /blurb-setup

Save your pen name, genre, voice, and go-to comps. Every run after that skips the questions and gets straight to the blurb.

Sound familiar?

Your blurb describes the plot but does not make anyone want to buy.
You have rewritten it ten times and it still falls flat.
You cannot tell a hook from a summary.
Browsers click away instead of clicking buy.

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.
