About Submagic

Submagic is a specialized video editing tool designed to maximize viewer retention on platforms like TikTok, Instagram Reels, and YouTube Shorts. The platform focuses entirely on the critical elements of short-form success: aggressive captions, sound effects, and fast-paced B-roll.

The AI automatically transcribes uploaded videos and applies highly stylized, animated subtitles that highlight keywords and inject relevant emojis. But it goes a step further by utilizing 'Magic B-Roll'. The AI analyzes the script and automatically inserts relevant stock footage or images at key moments to keep the viewer visually stimulated.

Favored by fast-paced content creators, Submagic eliminates the hours spent manually keyframing subtitle animations and sourcing stock footage, delivering ready-to-post viral videos in minutes.
