Hey Product Hunt! 👋 As someone working closely with animation, gamedev, and video reviews, I got tired of the usual friction with review tools: uploading massive 4K video files to the cloud, waiting on processing queues, dealing with clunky web interfaces, and worrying about client NDAs. Most animators and directors just want to scrub a clip, draw a quick line-of-action or timing arc, and keep working. That’s why we built FrameSketch. Here’s what makes it different: 100% Local & Offline-First: Video files are decoded directly in your browser using local file streams. Once loaded, you can literally turn off your Wi-Fi and review clips with zero latency. Hardware-Accelerated Brushes: We bypassed standard DOM/canvas bottlenecks and built a custom vector brush pipeline on WebGL. It supports Apple Pencil / stylus pressure, dynamic stabilization, and responsive tapering. PWA Ready: Use it right in the browser or install it as a lightweight app on your desktop. Core Free Forever: The local, offline video sketchpad is completely free with unlimited projects. We’re actively refining brush dynamics, stabilizer curves, and shortcut bindings, so we’d love your candid feedback on performance, feel, and features you’d like to see next. Try it out (no heavy setup or upload queues required): https://framesketch.xyz Thanks for checking it out! 🚀
