Hey Product Hunt! I built EchoFilter after watching my own contact forms get flooded with bot submissions. My sales pipeline was full of fake leads and I was wasting hours chasing ghosts. CAPTCHAs kill conversion. I wanted something invisible. EchoFilter runs a behavioral analysis on every form submission — mouse movement, typing rhythm, timing patterns — and returns a trust score (0-100) in under 100ms. Real users never see anything. Bots get flagged instantly. It's a single script tag. No SDK setup, no complex integration. For Product Hunt: first 50 users get 3 months Starter free — no card required. Just sign up at echofilter.com. Happy to answer any questions or hear brutal feedback. 🙏
