What is AutoCaption?
AutoCaption is an AI caption generator that automatically transcribes video audio and turns it into styled, timed captions for social videos. It is built to save creators from manual subtitle work by handling transcription, timing, styling, and export in one workflow.
The tool focuses on short-form and social-first content, with captions designed for TikTok, Instagram Reels, YouTube Shorts, and similar platforms. It supports animated styles such as word-by-word popups, karaoke highlights, and color emphasis, so the captions are meant to boost retention instead of looking like plain subtitle files.
AutoCaption also emphasizes speed and convenience. The site says most videos are captioned in under 10 seconds, captions are auto-detected in 100+ languages, and files can be uploaded in common formats like MP4, MOV, AVI, MKV, and WebM.
It is aimed at solo creators, daily posters, marketing teams, and agencies that need repeatable branded captions. The platform also offers templates, an editor for fixing text, auto-resizing for different aspect ratios, and an API for teams that want to automate captioning at scale.
