I Built an AI Tool That Audits Landing Pages (Flutter + Node.js + Claude API)

I built a full AI-powered landing page auditor from scratch — Flutter Web frontend,
Node.js backend, and Claude doing the heavy lifting in the middle.

Paste any URL → get a full CRO audit in 20 seconds. Headline score, CTA analysis,
trust signals, objection handling, conversion probability, and a 3-week priority roadmap.
All generated by Claude based on the actual content of your page.

In this video I walk through:
— How the 3-stage scraper works (Cheerio → Jina → Puppeteer)
— The Claude prompt that returns consistent structured JSON every time
— Clean Architecture + Cubit in a real Flutter production app
— Two-level caching (server + Hive on device)
— SSRF protection and why it matters if you're fetching URLs from users
