MioSub

MioSub is an AI-powered subtitle editor that automates the entire workflow from transcription through hardcoding. It uses Gemini AI to understand full video context before translating, supports 100+ languages, and includes intelligent terminology extraction, speaker recognition, and waveform-level alignment. The project describes itself as a free alternative to CapCut, VEED, and Descript.

Designed for content creators, translators, and video producers, MioSub processes videos in minutes with minimal manual intervention. Users paste a link or import local files, and the tool handles transcription, translation, timing alignment, and video compression automatically. The editor provides real-time preview and works with audio files, podcasts, and audiobooks alongside video content.
