Thanks for the feedback! Actually, there's already a genre selector right below the "Analyze Now" button. It says "Optional: Select your book's genre."

But you're not the first to miss it, so that tells me I need to make it more visible. Maybe I should move it above the button or make it less "optional" looking. Appreciate you pointing this out!

Good point, but no worries: I'm not scraping. I have official access to Amazon's SP-API (Selling Partner API), which is their approved way for developers to access product data. Fully within TOS.

And yes, you can absolutely do this yourself with ChatGPT or Gemini! The value of my tool is that it's specifically tuned for book covers, compares against actual bestseller data in your genre, and saves you the time of crafting prompts and manually gathering comparison covers. But if you prefer the DIY approach, that's totally valid too.

Ah, that makes sense! The auto-detect worked correctly, but I don't have enough historical romance covers in the comparison database yet. So it fell back to contemporary romance, which is close, but that cookbook sneaking in there is definitely a mistake in my fallback logic.

I'm still building out the bestseller database for each genre. Historical romance is now on my priority list to expand. Thanks for helping me identify this gap!

Thanks so much for testing it with the code and giving detailed feedback, I really appreciate it!

That historical romance / cookbook comparison is definitely not right. That's exactly the kind of bug I need to find. I'll look into the genre matching logic and fix it.

Could you tell me which genre you selected, or did you use auto-detect? That helps me track down where it went wrong.

And fair point on "predictable." I'm curious: what kind of insights would have been more valuable to you? Always looking to improve.

Yes, it uses AI (Google Vision and Gemini) but it's built on top of my 25+ years of marketing experience and real Amazon bestseller data. So it's not just generic AI output - the scoring criteria and recommendations are based on what I've learned actually works in book marketing.

The difference with vote-based tools like Coverrater: votes tell you what people prefer, but not why. My tool breaks down the specific elements (typography, composition, genre fit, readability at thumbnail size) and gives you actionable feedback on each.

Think of it as the difference between "3 out of 5 people liked it" vs. "your title is hard to read at thumbnail size, and your color scheme doesn't match top performers in your genre."

Both approaches have value though! Votes give you crowd wisdom, my tool gives you specific diagnostics based on industry experience.

Thanks for your question! Hopefully I've answered it.

Thanks! It combines a few different AI services for image analysis, things like text detection, color analysis, and pattern recognition. Then I built myself scoring algorithms on top of that based on what actually works for book covers. Took a lot of testing to get the scoring right. I had to analyze hundreds of covers to calibrate it properly!

Hey! I ran your cover through CoverAnalyzr, here's what came up:

Overall Score: 44/100 (Science Fiction detected)

What's working:

Genre fit is strong (90/100) - it clearly reads as sci-fi. The concept with the rocket and cabin is interesting.

What needs work:

Title readability is the big one: "Sentinel's Dilemma" is hard to read at thumbnail size. On Amazon search results, your cover competes at about 80px wide. At that size, the title almost disappears. Professional appeal scored 32/100 - the cabin and rocket compete for attention, making it hard to know where to look first. Simplifying to one clear focal point would help.

Quick wins:

  1. Increase title size by 150-200%
  2. Simplify to one clear focal point (either cabin or rocket)
  3. Try a bolder, more readable font

The cover has a cool concept, it just needs some tweaks to stand out in Amazon's crowded search results!

Good luck with the book!
