Offline Subtitle Studio AI is a Windows software designed to automatically create subtitles from video or audio files, while maintaining complete control over privacy. Unlike online services, it runs locally on your computer using AI speech recognition based on faster-whisper and CTranslate2. Your videos, audios, transcripts, and subtitles therefore never leave your PC, making it an attractive solution for creators, professionals, and users concerned about protecting their files.
The software allows you to generate subtitles, correct the text, adjust timing, apply styles, and export the result in several popular formats. Simply drag and drop a file into the application, start the transcription, and then edit the segments in a clear subtitle table. Offline Subtitle Studio AI can export to SRT, VTT, TXT, or ASS, create a separate subtitle file compatible with players like VLC, embed a selectable subtitle track, or burn the subtitles directly into a new video without altering the original.
