SubtitleGenerator is an AI-powered subtitle generator for adding accurate, editable captions to videos directly in a web browser. Upload an MP4, MOV, WebM, or MKV file to automatically transcribe spoken audio with word-level timing, then review and correct uncertain words, edit subtitle cues, adjust timing, and add captions where needed.
The app includes 33 subtitle styles across clean, creator, karaoke, cinematic, pop, and branded categories, with animated typography and visual highlighting for different content types. Users can preview captions on their video, translate subtitles, and export a captioned video or subtitle files in SRT, VTT, ASS, SSA, SBV, SMI, TXT, and JSON formats for workflows involving tools such as Premiere Pro and DaVinci Resolve. Video files remain on the user’s device while audio is processed for transcription, and video exports render in the browser. SubtitleGenerator is suitable for YouTube videos, TikTok and Instagram Reels, podcasts, interviews, tutorials, online courses, gaming clips, music videos, and other short- or long-form video content.
