FrameSketch

What is FrameSketch?

FrameSketch is the on-footage sketchpad built for animators. Step through frames, draw arcs and poses, drop sticky notes and comments, and review shots without ever leaving the timeline. Work directly on top of your footage in the browser, no uploads required. By default, everything stays on your device. Projects save as tiny .fsk files that are easy to email, share, or archive, with optional cloud sync for annotations when you need it. Built for precision and flow: frame-accurate drawing, onion skinning, vector strokes, layers, rulers, guides, and fluid pan and zoom. Animate faster. Communicate clearer. Iterate with confidence. Available in the browser today, with desktop apps for Windows and Linux coming soon.
