Auto Video Editor

Edit what you shoot into finished videos. Pick a style, upload your footage, and export the polished video for TikTok, YouTube Shorts, Instagram Reels, or LinkedIn.

Edit videos automatically in one click

AI Auto Edit generates captions from your audio, adds emojis, highlights key words, applies animations, and inserts contextual B-roll. Pick a style, upload your footage, and export a polished video in minutes.

Add zoom effects, remove silences, clean audio, and fix eye contact from the same editor.

Edit short-form videos faster

Captions and B-roll generate automatically when you upload. The Magic Tools below run with one click.

Generate captions in 50+ languages

Captions sync to your speech automatically with 98% accuracy, and you can pick from dozens of templates or customize typography, colors, and animations to match your style.

Generate AI B-roll that matches your transcript

The AI reads your transcript and inserts relevant clips from the built-in stock library or your own uploads. A simple slider controls how often B-roll appears.

Remove silences, filler words, and bad takes

Smart Trim analyzes your audio and removes dead air, filler words, and bad takes in one click, with Natural, Fast, or Extra Fast modes depending on how tight you want the edit.

Emphasize key moments with zoom

Magic Zoom adds emphasis at key moments based on your transcript, with four styles (smooth, crash, expo, linear) and AI-suggested placements you can adjust or add to manually.

Clean audio and correct eye contact

AI removes background noise and adjusts your gaze so you look directly at the camera, even when reading from a script. Both run with one click.

Save your brand kit for one-click consistency

Store your typography, colors, and caption styles once in a Brand Kit, then apply them instantly to any video for consistent output across content series or multiple clients.
