As answered by people managing AIMention and Cert Decoder.
AIMention's answer
AIMention was founded when it became clear that AI search is replacing Google — and most small businesses have no idea how they appear in it.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
AIMention's answer
Small business owners — plumbers, salons, landscapers — who want to show up when customers ask AI assistants for local recommendations.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
AIMention's answer
It's fast, affordable, and built for non-technical business owners. Get a free AI Visibility Score, then buy the full report for just $30.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
AIMention's answer
AIMention is the only tool that shows small businesses exactly how — and whether — they're mentioned by AI search tools like ChatGPT and Perplexity.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
