Turn client Looms, screen recordings and voice notes into developer-ready tasks, bugs, design changes, screenshots and acceptance criteria: each traceable to the moment it was asked for.
Video Player
A clean, private video player that runs in your browser, play any local MP4, WebM, MOV or MKV with variable speed, A→B loop, Picture-in-Picture, fullscreen and frame-by-frame stepping. Nothing is uploaded, nothing is processed.
MKV to MP4
Convert MKV to MP4 in your browser, usually a fast, lossless remux that just swaps the container so your video plays on phones, TVs, editors and the web. Nothing is uploaded.
