AutoSubtitles
AutoSubtitles is a web-based AI transcription and subtitling tool that automatically generates accurate captions and subtitles for video files. Users upload a video, and the service transcribes the audio using AI to produce a downloadable subtitle file (SRT/VTT) or burned-in animated captions. It is offered as a free tool with optional paid plans for extended usage, targeting content creators, educators, marketers, and businesses who need fast, accurate subtitles without specialist software.
