VTT Transcript Extractor

Get the full text out of almost any video you watch. Copy it, download it as a clean text file, or save it as a subtitle file (.srt, .vtt or .ass) with the original timings. Whether you're a student compiling notes from lectures and online courses, a researcher pulling quotes out of recorded talks, or a creator gathering reference material, this tool takes the hassle out of hunting down hidden subtitle files. Great for studying, summarizing a long talk, searching what was said, or pasting a transcript straight into an AI assistant. WORKS WITH: ✅ YouTube: auto-generated and manual captions, in any language ✅ Kaltura: the video system behind many university lecture portals ✅ Wistia: including the native player used by several course platforms ✅ Vimeo ✅ Loom ✅ Any site that serves standard VTT, SRT or TTML subtitles, including HTML5 <track> tags and HLS streams Tested platforms, in full: https://kissma.org/apps/vtt-transcript-extractor#supported-sites KEY FEATURES: 🚀 One-click or automatic: captures captions as the video plays, or pulls them from your current tab in a single click 🎞️ Subtitle files: download .srt, .vtt or .ass with the original timings, ready for media players, video editors and subtitle editors ⏱️ Timestamps optional: export plain text, or keep the timecodes 🌍 Clean languages: when a video has several caption languages, each one stays separate, so your files never mix them 📂 Live preview: read the text right in the popup before you export 🔒 Private by design: everything runs locally in your browser. Nothing you capture is ever uploaded, tracked, or stored on our servers 🌐 Lightweight: built natively so your browser stays fast A quick note on expectations: subtitles have to exist for a video, and a few platforms deliver them in a format we can't read yet. If a player only loads its subtitles while the video plays, the popup tells you to press play with captions on. Run into a site that doesn't work? The popup has a one-click "report this site" link. Tell us and we'll add support.
