Short-form creators usually have the right footage already sitting in their camera roll — they just don't know which clip fits which trending sound, and by the time they work it out the trend has peaked. B-Roll AI scans your library, matches your existing clips to trend-style audios, and tells you before the window closes.
No. The scanning and tagging happen on-device using Apple's Vision framework, so your footage stays on your phone. That is what 'local-first tagging' means on the rest of this page.
Each audio in the catalogue is tracked through its lifecycle — rising, peaking, fading. The app surfaces matches while a sound is still rising or peaking, and alerts you so you can post while the trend still has reach.
Free gives you one daily match alert and the full editor — trim, speed, 9:16, beat-sync. Pro covers every trend every day, shows all matching clips rather than the top three, and sends instant alerts instead of a single daily one.
For most short-form posts, no. The editor covers trimming, speed changes, 9:16 reframing, and syncing your cut to the beat of the chosen audio.
