Screen recordings and videos inside SuperTasks
SuperTasks (tasks.supertixs.com) uses TooLongToListen as its transcription engine: screen recordings and videos added to Documentos are transcribed, summarized and captioned there.
For your own pipeline, the API and MCP server take the direct URL of a media file, or an upload, and return text, SRT or VTT. Video page links such as YouTube are not accepted.
The video stays on your device
The video stays on your device. The audio is processed on our own server.
We do not download videos from links, transcribe live or separate speakers.
