Book Cover Checker

Though this is no substitute for human eyes, the book cover checker is kind of a fun tool. In their own words, the book cover checker is looking at contrast and sharpness, not at composition, or whether the cover fits your book, etc. It’s an algorithm. However, as I said, it’s pretty fun. I ran several of mine through (both my books and some I made for others) and got the GOOD rating. The most interesting part, I think, is that it also identifies the most used color in the cover (useful for matching backgrounds etc. for promotions). It’s not always what you think it is!

Easy to use, input an email address, upload your image, then scroll down a little for the result. I see it is now also looking for offensive content that some publishers won’t allow, so that’s interesting.

Anyway, thought I’d share! You can check it out here:

Have a great day!
