ON-DEVICE AI VIDEO EDITOR

Turn your clips into a video.

Montio's AI Cut finds your best moments, reframes to vertical, adds captions, and syncs to the beat — a finished, post-ready video in a tap. All on your iPhone. Nothing uploaded.

Coming to the App Store iPhone · iOS 18+ · free to try

Everything a post needs, done for you.

Montio does the tedious parts — cutting, framing, captions, music — so you just pick clips and post.

AI Cut

Pick a few clips, choose a look, and get a finished vertical video. Not happy? Remix for a fresh take in a tap.

Auto Shorts

Drop in one long video and Montio pulls out the best moments as a grid of ready-to-post shorts.

Karaoke captions

On-device speech recognition turns talking into word-by-word captions that light up as they're spoken.

Styles, on your footage

Vlog, Punchy, Cinematic, Travel, GRWM and more — preview each look on your own clip before you commit.

Made for every platform

Export presets for TikTok, Reels, Shorts, Square and YouTube — with captions kept out of each app's UI.

Private by design

Everything runs on your device. No account, no uploads, no tracking, and no metered "AI credits."

Your footage never leaves your phone.

Most AI editors upload your video to their servers and meter you by the minute. Montio does the opposite: the AI — best-moment detection, reframing, captions, translation — all runs on your iPhone.

That means it works offline, there's nothing to leak, and there are no per-video costs.
