A/B cover test
Compare two cover directions before you publish
A/B Cover Test is an AI tool that scores two cover directions head to head and tells you which one to launch with.
Not sure which cover is your best shot? Upload two options and set the reader, platform, and tone you want to win — we'll score both and tell you which one to launch with.

Frequently asked questions
How does the A/B Cover Test work?
Upload two cover directions along with your genre, target reader, and platform — BookScore scores both and tells you which one to launch with.
Does testing two covers cost 2 credits?
No — a full A/B Cover Test costs 1 credit total, same as any other BookScore tool run.
Can other authors vote on my covers too?
Yes — you can optionally publish your test for real reader votes from other signed-in authors, alongside the AI scoring.
What if I only have one cover?
Use Cover Score instead — it's built for scoring a single cover on its own.
