Hey Product Hunt 👋 I'm Dimitri, co-founder of Mockingbird. The idea came from a frustration we kept seeing: product teams shipping features blind not because they don't care about UX, but because usability testing is genuinely painful. Recruiting participants, coordinating sessions, waiting days for results. Most teams just skip it. So we built Mockingbird. Paste a URL, and our AI personas browse your site like real users — clicking, exploring, hitting dead ends — then hand you back a full video replay and a structured findings report, broken down by severity. No recruiting. No scheduling. Usability testing in minutes. We're early-stage and hungry for feedback. If you run a product, design, or growth team, or just want to see where your site breaks, we'd love for you to give it a go. Drop any questions below. We're watching closely today 🐦
