PageLint - Your landing page copy, audited like Ogilvy would

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.
