Right. It happened.
Last Thursday I went live on TikTok, pulled up a piece of software I built from scratch, and demoed it in real time to about 40 people. No safety net. No rehearsed walkthrough. Just: here it is, let's run some real products through it, and please tell me everything that's broken.
The thing? It worked.
The tool is called Score My ASIN. And this week I want to tell you exactly what it is, why I built it, and what I learned from doing a very sweaty, very real live demo.
Key Takeaways
What is Score My ASIN?
It's a website and Chrome extension that analyzes any Amazon ASIN and tells you — in about ten seconds — whether it's worth buying, testing, or avoiding entirely. Score of 0–10. Written verdict. Recommended action.
It pulls in live Keepa data, looks at buy box rotation history, seller counts, BSR, expected monthly sales, seller sizes, and fees — then runs all of that through the logic I've built up over five years of sourcing. The whole thing is basically my sourcing brain, productized.
Why did I build it?
Because tools like SaaS and BuyBot Pro are great at surfacing data — but you still have to make the call yourself. You still have to stare at the Keepa graph and go "right, what does this mean?" I wanted to remove that step. I wanted a tool that does the deciphering, not just the presenting.
Also — and I'll be honest here — I've never written a line of code in my life. I did this entirely with AI. Three weeks of back-and-forth with Claude. Eight pages of notes where I basically downloaded my brain. Then I turned those notes into a product.
If that's not the most 2025 thing I've ever done, I don't know what is.
Highlight Reel
The best moments from the live:
Zero out of ten. I picked a Hose Lock product that had 61 sellers on the listing — 182 at its peak. Before I ran it I told the chat: "I'm hoping my software comes back with a strong no." It came back zero. "Extreme seller count. Automatic avoid." Chat went mad.
12 bugs in 90 minutes. People spotted issues and I wrote them all down live. Couldn't convert to US dollars. Same ASIN counted twice against your daily allowance. No VAT toggle. Variation handling was a bit off. I'm fixing all of them this week.
"VAs are going to be out of work very, very soon." Someone in the chat mentioned they'd replaced their VA entirely using Claude AI and saved £700. Jaws dropped. (Mine didn't — I believe it completely.)
Near 10K followers. We hit 9,900 during the live. We are literally 100 away. If you're reading this and you're not following — now is the time.
Three sign-ups. During the live, three people signed up for the founder tier (£9.99/month for life for the first 50 users). To those three: thank you. Genuinely.
Behind the Scenes
I'll tell you something I didn't really say on the live: I was nervous.
I've done plenty of lives before. I know the format. But this one was different because I was showing something I built. Something I care about. And if it crashed, or gave completely wrong answers, or just didn't work — that was going to be in front of 40 real people.
It held up. Not perfectly — we found things that need fixing, and I'd expected that. But the core decision engine? The bit where it looks at a product and goes "yes, no, or maybe"? That worked. And when the software agreed with my own assessment on product after product, in real time… I genuinely couldn't believe it.
I'm going to keep doing lives to demo it. Not just because TikTok nudges you to, but because the live feedback format is genuinely how I want to develop this. You break it, I fix it. That's the loop.
Score My ASIN is free to try right now.
Five free uses, no card required. Seven-day free trial. First 50 sign-ups get it for £9.99/month for life. Everyone after that pays £19.99/month.
Go find something that doesn't work and send me a DM. I mean that.
