What is Submagic?

Submagic is an AI-powered video captioning and short-form video enhancement tool designed to help creators add highly engaging, animated subtitles to videos in seconds. It is primarily built for short-form content platforms such as TikTok, Instagram Reels, YouTube Shorts, and LinkedIn videos, where captions significantly impact watch time, engagement, and accessibility.

Unlike basic subtitle generators, Submagic focuses on viral-style captions—automatically highlighting key words, adding emojis, sound effects, and dynamic animations that keep viewers hooked even when watching without sound.

Key Features of Submagic

AI-Powered Auto Captions

Submagic automatically transcribes speech into captions with high accuracy, even for fast-paced or conversational content. The AI handles filler words, slang, and natural speech patterns better than traditional subtitle tools.

Viral Caption Styles & Animations

One of Submagic’s biggest strengths is its pre-built animated caption styles inspired by viral creators. These include:

• Word-by-word animations

This makes videos more scroll-stopping and engaging.

This saves creators hours of manual editing.
