SubtitleAI uses advanced AI speech recognition to transcribe spoken audio in video files into text, then applies AI-powered translation to convert transcripts into target languages. It supports single or batch processing of local video files (e.g., MP4, MKV) and exports subtitles as SRT files or burns them directly into videos. Users configure API keys for speech-to-text and translation services, specify languages, and run simple CLI commands. With options for timestamp adjustments and subtitle styling, SubtitleAI streamlines subtitle creation and localization workflows for content creators, educators, and marketers, eliminating manual transcription and translation steps.
