HappySRT

HappySRT is an open source web app for transcribing audio and video, translating the result into multiple languages and generating summaries. A user uploads a media file and receives a transcript, translations and a summary, and the name points to subtitle output in the SRT format. The app loads an in browser FFmpeg engine, which handles media processing on the client. It has sign in and keeps a history of past threads so earlier work can be revisited. The site does not publish a feature list beyond the transcription, translation and summarization description, so details such as supported languages, file size limits and export formats are not stated on the page. It suits people who need subtitles or written records from recordings, such as video creators, interviewers and anyone working across languages, and developers who want to inspect or run the code themselves because the project is published as open source. Pricing is not shown on a pricing page. The site's structured data lists a price of zero, and the product is described as open source, but the vendor does not publish paid plans.
