Perso AI, from South Korean software company ESTsoft, is an AI dubbing, avatar, and voice platform that translates videos into 99+ languages while keeping the original speaker on screen ā voice, face, and all.
Unlike avatar-first tools that generate a new presenter, Perso AI localizes footage you already have. Its dubbing stack detects speech in more than 99 languages, translates the script, clones each speaker’s voice, and rebuilds lip movements frame by frame so the dubbed video matches the original performance. Multi-speaker detection handles up to 10 speakers per video, and a real-time script editor lets you fix wording before export. The wider Perso family adds interactive AI avatars, a Korean avatar production studio, and LiveDub ā real-time AI dubbing for Zoom and Google Meet calls.
A free tier includes one dubbed video on sign-up (1 minute, watermarked). Paid credit-based plans start with Starter at $6.99/month, Creator at $29/month, and PRO at $99/month with up to 4K export, while Enterprise is custom-priced. Credits convert to dubbing minutes, and higher tiers raise per-video length limits.
Perso AI also benefits from its parent company’s footing: ESTsoft is a publicly listed Korean software company founded in 1993, which gives the platform an enterprise maturity unusual among dubbing startups. The product family keeps expanding around the core engine ā an interactive avatar platform for kiosks and a real-time translator for in-person conversations share the same voice and avatar technology.
Perso AI fits YouTube creators, course producers, marketing teams, and enterprises that want to republish existing videos for global audiences while preserving each presenter’s real voice and on-screen presence.
