PERSO.ai

Perso AI is a 3-in-1 AI audio and video platform combining AI Dubbing, Speech-to-Text, and Audio Separation in a single workflow. It translates and dubs videos into 33+ languages with natural voice cloning and lip dubbing, generates speaker-separated transcripts with automatic speaker diarization in four output formats (XLSX, SRT, VTT, JSON), and isolates individual speaker voices from background audio with dual modes (vocals-only or with reactions preserved). Trusted by 460,000+ users across 80+ countries, powered by the ElevenLabs voice engine (2025 partnership), and ISO/IEC 27001 and KISA ISMS certified. Developed by ESTsoft (est. 1993, KOSDAQ: 047560). Starts at $6.99/month with up to 98% cost savings vs. traditional dubbing studios.
