A Privacy-First Video Captioner That Runs in Your Browser

I’ve been looking for a simple way to add captions to short videos without uploading them anywhere. Most tools require you to send your file to a server, which isn’t ideal for privacy or speed.Recently

It’s a web tool that runs completely in your browser using Whisper AI. You select a video (or audio file), it transcribes and adds captions — nothing ever leaves your device.

What I like about it:

  • No sign-up required
  • Works offline after the model loads
  • Clean presets: TikTok-style, Classic, Minimal, Karaoke
  • You can edit the transcription directly
  • Built-in audiogram generator for podcast clips
  • Exports as WebM with embedded captions

The first time you use it, it downloads a ~74MB model. After that, everything is fast and local.I’ve been using it for Reels and short clips. It’s quick, looks good, and gives me full control without relying on third-party services.

If you create short-form content and care about privacy (or just hate uploading videos everywhere), give it a try. It’s one of the cleaner tools I’ve used in this space lately.Would love to hear if others have tried it or found similar browser-based tools.
