Overview / Description
aicaption is an AI video caption generator that adds captions to short-form videos online and styles them for TikTok, YouTube Shorts, and Instagram Reels. It turns spoken audio into timed caption text automatically, so you spend less time lining up subtitles by hand, then lets you style the words before exporting. The browser-based workspace keeps the core steps together: upload a clip (MP4, MOV, or WebM), generate AI captions, adjust the visual treatment, preview, and download, with an SRT export option for editing elsewhere. Caption styles are built for vertical mobile feeds and include high-contrast presets such as an orange hook style, a yellow highlight for tutorials, and a cyan karaoke look for Reels, all designed to stay readable when viewers watch with sound off. Because it runs in the browser, there is no desktop editing software to install. The primary audience is creators and small teams publishing talking-head clips, product demos, tutorials, and social edits who want repeatable caption projects with upload, generation, and history in one place. Note that aicaption is not affiliated with TikTok, YouTube, or Instagram.
