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.", "body_md": "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\n\nVideo Captioner by [Utilora Link](https://utilora.app/tools/ai-tools/video-captioner)\n\nIt’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.\n\nThe 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.\n\nIf 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.", "url": "https://wpnews.pro/news/a-privacy-first-video-captioner-that-runs-in-your-browser", "canonical_source": "https://dev.to/pure_lifetribe/a-privacy-first-video-captioner-that-runs-in-your-browser-2h72", "published_at": "2026-05-29 05:15:16+00:00", "updated_at": "2026-05-29 05:42:25.677992+00:00", "lang": "en", "topics": ["ai-tools", "artificial-intelligence", "computer-vision", "ai-products", "ai-startups"], "entities": ["Utilora", "Video Captioner", "Whisper AI"], "alternates": {"html": "https://wpnews.pro/news/a-privacy-first-video-captioner-that-runs-in-your-browser", "markdown": "https://wpnews.pro/news/a-privacy-first-video-captioner-that-runs-in-your-browser.md", "text": "https://wpnews.pro/news/a-privacy-first-video-captioner-that-runs-in-your-browser.txt", "jsonld": "https://wpnews.pro/news/a-privacy-first-video-captioner-that-runs-in-your-browser.jsonld"}}
