After you have looked at your own landing page twenty times, you cannot see it anymore. You know where the pricing link is, so it feels obvious. You know what the product does, so the headline reads fine. Every founder I know has this blind spot and none of us can fix it alone.
So I built FiveStrangers. You give it a URL and pick what visitors are supposed to do there (sign up, call you, buy something). Then five AI visitors open your site in a real browser, one at a time, each with a different personality:
\- the Google skimmer, who gives your page ten seconds before leaving
\- the mobile ad clicker, browsing on a phone with no patience
\- the skeptical evaluator, who reads everything and hunts for proof
\- the comparison shopper, who has three competitor tabs open
\- the ready buyer, who just wants to convert and counts every obstacle
They scroll, click your buttons, follow links across pages, and narrate what they are thinking the whole time. At the end each one either converted or bounced, and you can see the exact moment you lost them.
While that runs, the boring measurable stuff happens too: Lighthouse performance, accessibility, broken links, SEO, security headers, and whether ChatGPT and Perplexity are even allowed to crawl your site. All of it turns into one score with the evidence attached.
Two things it found on a real site I tested it against, a nursing service in Berlin:
The skeptical visitor read the entire site, then refused to call. Its reasoning: the page says "certified nursing service" but never names a certificate, an authority, or a date. For a business where families are handing over care of a parent, that gap killed the conversion by itself.
The comparison shopper clicked the "call us now" button on the contact page and nothing happened. It focused a form field instead of starting a call. Nobody had noticed. That is a real bug that was quietly costing phone calls.
What it is not: a guarantee, or a replacement for talking to actual users. The findings are automated, and I make it cite what a visitor actually saw or a number that was actually measured, because "your CTA could be stronger" helps nobody.
Status: my payment provider has not approved the store yet, so it is early access at the moment. You can put in your site and I will email you the moment audits open. There is also a complete example report you can download without giving me anything, so you can judge the output before deciding.

Price when it opens is 12.99 one time per audit, no subscription. Happy to answer anything about how the agents work, and honestly interested in hearing where you think this falls apart.
