Publisher Rocket for keyword research. KDPEasy for the whole workflow.
Rocket is the category-leading one-shot KDP keyword tool. KDPEasy bundles the same keyword research with AI cover generation, interior builders, royalty math, and description writing in one subscription. Here is the honest, side-by-side comparison.
What Publisher Rocket does well
Publisher Rocket (Dave Chesson / Kindlepreneur) has been the category leader for KDP keyword research since 2017. The honest take: it earns its reputation in one specific job.
- Category leader since 2017Dave Chesson built the first serious KDP keyword tool. Big install base, active community, ten years of pattern recognition baked into the data layer.
- AMS keyword suggestionsThe "Amazon Ads Keyword Search" feature surfaces high-intent ad keywords pulled from Amazon's own auto-suggest, useful when running Sponsored Products campaigns.
- Category browserBrowse Amazon's book categories with sales-rank and revenue estimates side by side. Great for sniffing out under-served micro-categories.
- Competitor analyzerPull a snapshot of the top books for a keyword (price, reviews, est. monthly sales). Useful before committing to a niche.
What KDPEasy adds
Keyword research is one step. KDPEasy treats the whole KDP workflow as the product: research, cover, interior, description, royalty math.
- Keyword research is one piece, not the productKDPEasy treats keywords as one step in a longer workflow: research, cover, interior, description, upload. The same subscription covers all of them.
- AI cover generation in 2 minutesGenerate a print-ready full-wrap cover (front, spine, back, bleed, 300 DPI) from your title and page count. The piece Rocket cannot help you with.
- Interior builders for low-contentPuzzle books, journals, planners, coloring books, log books. Generate interior PDFs alongside the cover. This is where most of the volume is for many KDP authors.
- AI-powered description generatorTurn your keyword research into a benefits-led Amazon book description with HTML formatting. Direct paste into KDP.
- Royalty and trim calculatorEnter your trim, page count, and list price. Get exact royalty per channel including print cost. Rocket has only a basic estimator.
- Subscription consolidationMany KDP authors pay for Publisher Rocket + Canva + Fiverr designer + Atticus + Vellum. KDPEasy collapses the cover, interior, description, and research tools into one subscription.

When Publisher Rocket is still the right choice
Be honest about who Rocket is built for. If all of the following are true, buy Rocket and skip the rest of this page:
- Your only need is keyword and category research. You already have a cover workflow you trust (designer on retainer, Canva subscription, Vellum license).
- You run high-budget Amazon Ads ($200+/month) and need the deep AMS keyword finder for daily campaign tuning.
- You prefer a one-time license over a subscription, and you only publish 1 to 3 books per year.
Outside those conditions, the subscription consolidation case for KDPEasy gets stronger book-by-book.
The KDP author tool stack most authors actually run
Most serious KDP publishers do not just buy Rocket. They buy a stack. Here is the typical traditional stack, and what KDPEasy collapses.
| Tool | Job | Cost | Replaced by KDPEasy? |
|---|---|---|---|
| Publisher Rocket | Keyword research | $97 once | |
| Canva Pro | Cover design templates | $120 / year | |
| Fiverr designer | When templates fall short | $150 / cover | |
| Atticus | Interior formatting | $147 once | |
| ChatGPT Plus | Description writing | $240 / year |
Prices reflect typical 2026 retail. Many authors do not run every tool in this stack, but most run at least three of them.
What 3 years of KDP publishing actually costs
Assumes 5 published books per year over 3 years (15 books total). Cover outsourcing at 5 covers per year through Fiverr is conservative.
Traditional stack (3 years)
- Publisher Rocket (one-time)
- $97
- Canva Pro ($120/yr x 3)
- $360
- Fiverr cover designer ($150 x 15)
- $2,250
- Atticus (one-time)
- $147
- ChatGPT Plus ($240/yr x 3)
- $720
- 3-year total
- $3,574
KDPEasy (3 years)
- Subscription ($19/mo x 36 mo)
- $684
- Cover generation (included)
- $0
- Interior generation (included)
- $0
- Keyword research (included)
- $0
- Description writer (included)
- $0
- 3-year total
- $684
Math assumes you actually use the stack. Many authors carry these subscriptions without using them, which is the real waste. Either way, consolidation reduces cognitive overhead.
