AI scans the transcript of your long video or YouTube link, extracts the most interesting topics and returns multiple vertical clips in minutes.
Scene-aware reframing keeps the active speaker or key action centred, with split-screen, screencast and gaming layouts for 9:16 output.
Transcription and word-highlighted subtitles across 99+ languages, with custom fonts, colours, logos and AI-drafted caption copy.
