What it does

Use aicaption as an AI video caption generator to add captions to video online. Create styled captions for TikTok, YouTube Shorts, and Instagram Reels.

Generate AI captions from video speech, choose from 30 styles, and export a ready-to-post MP4 while keeping your audio, layout, and quality up to 4K.

Turn video speech into timed captions, choose from 30 styles, and export a ready-to-post MP4 while preserving the original audio, layout, and quality up to 4K. Upload an MP4, MOV, WebM, M4V, or GIF file up to 5GB. Videos at 1080p or below can run up to 2 hours; higher-resolution videos can run up to 1 hour. Use a short video to test the complete automatic caption workflow. Start from spoken audio, upload an existing SRT file, or paste timed subtitle text. Every path leads to the same focused styling and video export workflow. Upload a video with spoken audio and let AI Caption create the subtitle text and timing before applying your selected style. Bring an existing timed subtitle track…from aicaption.com

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
