Genre-tuned by reverse-engineering 100 bestsellers per subgenre.
The math of every launch

You release a book every 30–60 days.
Each launch eats a weekend.

The book is the easy part. Then comes the blurb you'll rewrite four times, the keywords you'll guess at, the categories Amazon hides, the A+ Content you'll either skip or pay $150 on Reedsy for, and the 20 ad variants you swore you'd write but didn't. So your book launches half-naked.

Then you do it again next month.

The kit

Five Amazon assets. One $19 kit. 90 seconds.

Why this works

Built for KDP. Not for ChatGPT.

Generic AI tools write generic blurbs. We've reverse-engineered the Top 100 Amazon bestsellers in your subgenre — every output is tuned to what readers in your niche actually click on.

Genre-tuned

A LitRPG blurb shouldn't sound like a regency romance. We have separate prompt scaffolds for every subgenre — hook patterns, voice, forbidden words, sample openings.

KDP-formatted

Blurb under 4,000 characters. Keywords trimmed to 7×50 char slots. Ads split by type. Every output is the exact shape Amazon wants. No reformatting.

Owned, not rented

Pay $19 per book. Or $29/month if you grind. No subscription required. No Publisher Rocket-style $97 sunk cost. Cancel anytime if you upgrade.

Pricing

Pay per book. Or grind unlimited.

No free trial games. No "starting at" pricing. No annual lock-in unless you want it.

Before you buy

The questions you were going to email us anyway.

Will Amazon ban me for AI-generated metadata?

+

No. KDP's policy requires disclosure of AI assistance for prose; metadata, blurbs, and ads copy are not regulated the same way. You're the author of record on everything we generate.

Is my synopsis used to train models?

+

No. We route through OpenRouter with no-train flags on DeepSeek and Gemini. Your synopsis is deleted from our logs after 30 days.

What if the blurb is generic?

+

You get 9 blurb variants per kit (3 hook angles × 3 lengths) and unlimited regenerations on Pro. Most authors keep one variant verbatim and tweak two. If none work, hit the 7-day refund.

How is this different from Sudowrite or NovelCrafter?

+

Those write your book. We write everything that goes around your book on Amazon — the blurb, the metadata, the ads. We don't compete; many of our users use both.

How is this different from Publisher Rocket?

+

Rocket finds keywords. We find keywords AND write the blurb, A+ Content, categories, and ads — and we cost $19 instead of $97. We also update for new KDP fields the day they ship.

Can I get a refund if it's bad?

+

Yes. 7-day no-questions refund on per-book purchases. 14-day on Pro. We don't ask why; one click in the dashboard.

Do you support non-fiction or memoir?

+

Not in v1. We're fiction-only on launch — paranormal romance, LitRPG, cozy mystery, military sci-fi, and regency romance. New subgenres ship monthly.
