What is Submagic?

Submagic is an AI tool specifically optimized for short videos, focusing on "one-stop subtitle creation and editing". Whether a short video can retain viewers often depends more on the rhythm of subtitles, the highlighting of key words and the speed of scene switching than on the content itself, and doing these manually is extremely time-consuming. Submagic uses AI to automatically generate subtitles, add expressions and special effects, remove redundant words and pauses, and quickly cut long content into short clips suitable for social media, allowing creators to focus on topic selection rather than mechanical editing. It is especially suitable for short video accounts focusing on oral broadcasting, tutorials and live streaming with goods, and is one of the representative products of "AI-native short video post-production".

Who is it for?

Short video creators who do voice-over, tutorials, or live streaming sales.
Teams that need to batch-produce Reels/Shorts/TikTok.
Accounts that want to translate content into multiple languages for overseas expansion.
Freelancers and agencies engaged in short video operation services.
People who pursue efficiency and don't want to manually sync and add subtitles.

How to use Submagic

1Speak clearly and reduce filler words during recording, which can significantly improve the quality of automatic editing.

Archive the finished clips into a template library, apply them directly to similar content, and save a lot of time on repeated settings in the long run.
