Context Desk — Demo video

Context Desk is an AI clip farming studio. It turns live streams and long episodes into story-complete, subtitled Shorts in any language, on the editor's own computer. The problem: clip channels and small creators spend hours scrubbing long streams and episodes for moments worth posting, then subtitling them, often from a language they don't speak. Most auto-clippers cut random high-energy seconds and machine-translate them, so the clip loses the story and the meaning. What it does: - Paste a link, upload a video, or point it at a YouTube, Twitch or Kick live stream. - Meta Muse Spark reads sampled frames and the transcript and finds complete moments: a setup, a turn and a payoff. Every clip gets an English title, a reason and its place in the source. - Muse Voice transcribes speech in 25 spoken languages. Muse Spark writes natural, dialect-aware subtitles and flags every line it is unsure about, so the editor checks the right words. - Culture notes explain slang and references on screen. - One click reframes to 9:16 with face tracking. It adds caption styles, title cards and a post kit (caption, hashtags, notes). - An optional English dub clones each speaker from their own line. - For the whole episode it writes chapters, answers questions (Ask the episode) and renders a one-minute trailer. - Live clipping records shared streams at up to 1080p in the background, with a monitor window and an alert for every new clip. In our test, a 4-minute episode excerpt gave 4 ready clips in about 2 minutes, and 125 English subtitle lines for the excerpt in about 2.5 minutes. Everything was built during the hackathon: the repository's first commit is 31 Oct 2026, and all 123 commits fall between 31 Oct and 4 Nov. The code is open source (MIT).
