About Auto-Caption AI Studio
Auto-Caption AI Studio generates subtitles and animated captions for videos directly on a user’s computer using a local Whisper AI engine. It supports MP4, MOV, MKV, MP3, and WAV files, transcribing speech into word-by-word timestamps without cloud uploads. Users can choose from 16 preset caption styles across Minimal, Bold, Cinematic, Aesthetic, and Social categories, including effects like Active Glow, Neon Cyber, Retrowave, and Handwritten Notes. The tool highlights spoken words with real-time animations such as pop, glow, bounce, and underline, optimized for platforms like YouTube Shorts, TikTok, and Reels. Captions can be positioned and styled before exporting as ready-to-post MP4 videos with burned-in subtitles or as standalone subtitle files in SRT, VTT, or ASS formats. The application is designed for video creators seeking viral-ready captions with precise timing and customizable visual effects.
