Vidzerunok is a cross-platform video frame annotation tool built with Kotlin Multiplatform and Compose Multiplatform. It lets you extract a frame from a video, enhance it visually, annotate it with simple elements, and export or share your result.
✨ Inspired by the Ukrainian word “візерунок” meaning “pattern” or “ornament,” Vidzerunok blends creativity and precision into a clean visual editing experience.
