About HappySRT

HappySRT is a free, open-source web application that transcribes audio and video into timestamped transcripts, translates them into multiple languages, and generates summaries. It's aimed at anyone who needs subtitles or text from media -- content creators, video producers, and localization workflows -- organizing each job into revisitable 'thread' workspaces. Its main differentiator is being fully open-source with in-browser FFmpeg processing and one-click SRT subtitle export.
