Hey Product Hunt, I'm Danylo, solo founder from Kyiv. I've shipped too many landing pages with hero lines only I understood. What I needed each time was a conversion copywriter to tear the page apart, and $500+ for one page wasn't happening. So I built the auditor I needed. PageLint runs your page through 55 checks across 9 copywriting lenses, from clarity and value to trust, friction, and dark patterns. Every finding quotes the exact line from your page, proposes a concrete fix, and cites its source (Ogilvy, Cialdini, Schwartz, CXL research). The tool shows its receipts instead of handing you a vibes-based score. To prove the engine works, I ran it on 12 famous SaaS landings. The teardown gallery is public at pagelint.dev/audits: Mailchimp scored 92, Stripe 83, Webflow 66. Vercel fails the hero five-second test. Limitations: English-language pages only, and it audits copy, not design. The free quick audit is 16 checks, no signup, about a minute. The full report is $29 one-time, no subscription. Two asks: tell me where the audit gets it wrong (I read everything), and tell me which famous landing page I should tear down next.

Ran it on our homepage and the "every finding quotes the exact line" thing actually held up, even pulled a Schwartz reference I'd never have found myself. Surprised how blunt it was about our trust section being weak.

 That's the engine doing its job — the Schwartz material produces most of the findings people say they'd never have caught. Blunt is deliberate: a polite audit is a useless audit. If fixing that trust section moves your numbers, tell me — at this stage one before/after story is worth more to me than a hundred upvotes.

love that every suggestion cites the exact source behind it, that's the kind of transparency the audit space has been missing

 Thanks Bayram. The citations started as my own trust problem — I wouldn't act on "add social proof" advice without knowing where it came from, so every check had to carry its receipt. If there's a famous landing page you want torn down next, name it — the gallery has room for a second batch.
