SubHero takes your audio and turns it into publish-ready subtitles. It transcribes, corrects errors (homophones, stutters, filler words), breaks lines at natural sentence boundaries, then translates with a 3-stage review pipeline.
Pick from 9 AI models (GPT, Claude, Gemini, DeepSeek, etc.) and content-type modes tuned for anime, drama, documentary, and more.
Edit results in a built-in editor with waveform visualization. Pay only for what you use — credits never expire.
