Submagic

Submagic automatically generates animated captions for short-form videos using AI, creating the stylized, word-by-word caption animations common on TikTok, Instagram Reels, and YouTube Shorts. It adds emoji, word highlights, and visual effects to make captions more engaging and increase watch time. Content creators, social media managers, and marketing teams use Submagic to add professional-looking captions to short-form content in minutes rather than hours of manual editing. The AI also generates B-roll footage and adds viral sound effects automatically. Submagic targets the specific challenge of short-form video captions: unlike traditional transcription tools that just add static text, it produces the dynamic, animated captions that have become standard in successful short-form content. This distinction drives strong word-of-mouth among video creators.
