7-day free trial · 30 free minutes · no credit card
Paste a YouTube link or upload raw footage straight from your phone. Big files welcome — uploads resume if your connection hiccups.
It finds the strongest moments, writes a scroll-stopping hook, cuts to vertical, and burns in word-by-word animated captions in your style.
Get ranked, publish-ready clips with virality scores. Pick the winners, post them everywhere.
Every one of these was captioned and cut automatically — no editing software, no timeline.
Not just captions on a video — a modern edit: hooks, pacing, style.
Scans the whole video and ranks the most clippable moments with a virality score, so you post the winners first.
Word-by-word animated captions in 4 styles — bold, minimal, karaoke, TikTok — with your highlight color and font.
Every clip opens with an AI-written hook line built on curiosity gaps and bold claims.
Filmed on your phone? ClipBoost cuts the silences and filler, adds punch-in zooms and swoosh cuts, and hands back a tight edit.
Whooshes on cuts and contextual image pop-ups — say “iPhone” and one pops on screen at that exact word.
Open any finished clip in the editor: correct a caption, change the color, trim the ends, re-render in one click.
Start free. Upgrade when the clips start working.
Talking-head content shines: podcasts, interviews, vlogs, streams, lessons. Anything where someone says something worth clipping — in any format, from a YouTube link or a file off your phone.
Zero. The AI does the full edit. If you want to tweak something afterwards, the built-in editor lets you fix captions, colors, and trims without any editing software.
Typically a few minutes per video. You'll see live progress, and each clip appears as soon as it's rendered.
7 days and 30 minutes of source video — enough for several videos' worth of clips. No credit card needed to start.
