Turn a single photo into a realistic, live-speaking AI persona — fully automated in minutes. Until now, real-time AI avatars required complex setups and high ongoing costs. PhotoCall changes that: create production-ready, photo-realistic personas that can speak and react live — with near-zero runtime overhead. ✓ Just 1 photo — everything else is automated ✓ Realistic & expressive — built from real photos ✓ Live conversations in real time ✓ Ultra-light runtime — no heavy infrastructure needed

Hey Product Hunt! 👋 We built Overlay Avatar because we believe everyone should be able to have a live, animated digital version of themselves — without any technical hurdles. The problem: creating a realistic speaking avatar traditionally requires expensive studios, complex 3D software, or hours of manual work. Our solution: upload one portrait photo. That's it. Our platform automatically generates a fully animated, live-speaking avatar in the background — ready to use for real-time conversations, presentations, or demos. What makes us different: → Truly one-step: just 1 photo, no editing or manual steps → Live & interactive in real-time → Pay-per-use (from €0.01/credit) — no subscription lock-in → Public demo avatars you can try instantly without signing up We'd love your feedback — try a demo avatar at avatar.letkimdoit.com!
