Most KDP authors pick niches based on gut feel — then spend months writing books no one buys.
You can't see BSR, review counts, or sales velocity without digging through Amazon manually.
Serious publishers spend 5–10 hours per niche just to validate whether it's worth pursuing.
Competitors charge $47–$99/mo for features most KDP authors don't even use.
Most KDP tools require a credit card upfront. You're paying $47+ before you know if it works for you.

No. KDP Radar is 100% browser-based. No extension to install, no permissions to grant, no setup. Open kdpradar.com in any browser and start researching in under 60 seconds. This is a deliberate design decision — extension installs create friction and break on browser updates.
