What is Submagic?
Submagic is an AI tool designed to automatically generate captions for video content. It analyses video files and produces text captions that synchronise with the spoken dialogue or audio, saving creators significant time on manual captioning work. The tool is aimed at content creators, social media managers, and video producers who need captions for platforms like TikTok, Instagram Reels, YouTube Shorts, and other short-form video services. Submagic handles the transcription and timing automatically, which is particularly useful for creators producing high volumes of video content who would otherwise spend hours captioning manually.
