LaunchKit vs Publisher Rocket
Publisher Rocket has been the indie-author keyword tool for a decade. It does keyword research very well. But it doesn't write your blurb, your ads, or your A+ Content — and at $97 one-time, you're paying upfront for software that hasn't materially changed since 2020.
LaunchKit costs $19 per book. We do keywords and categories and blurbs and A+ Content and 30 Ads variants. Here's the honest side-by-side.

When Publisher Rocket wins
If you only need keyword research, you've already got a polished blurb you wrote yourself, you don't run Amazon Ads, and you prefer a one-time desktop tool — Publisher Rocket is mature and reliable. Its keyword database is its core strength. We respect it.
When LaunchKit wins
If you release multiple books per year, hate writing blurbs, want Amazon Ads copy that doesn't take an evening, or you'd rather pay per book than $97 upfront for a tool you might use twice — that's our shape. We assemble everything Amazon needs in 90 seconds.
The honest take
A lot of indie authors use both. Rocket for the deep keyword dives once a year, LaunchKit for the per-book launch grind. They aren't really competitors — they overlap on one feature (keywords) and otherwise solve different problems.
