A Privacy-First Video Captioner That Runs in Your Browser

Utilora has released a browser-based video captioning tool that runs entirely on the user's device using Whisper AI, eliminating the need to upload files to external servers. The tool downloads a 74MB model on first use, after which it transcribes and adds captions to video or audio files locally. This approach prioritizes privacy and speed for short-form content creators.

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 Video Captioner by Utilora Link https://utilora.app/tools/ai-tools/video-captioner 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. 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.
