The app
Fast drawing, directly on glass.
Milenko Sketch is a lightweight desktop sketching and annotation tool built for speed and freedom. It lets you draw directly over your desktop using a transparent overlay.
This means you can sketch over reference images, videos, game engines, documents or live software without switching windows. It is ideal for rough ideas, concept art, animation blocking, quick notes or classroom demonstrations.
Controls are kept simple so the tool never gets in your way. Scroll to adjust brush size, press A to toggle transparency, press D to show or hide your palette, and press V to play animation.
Features
Sketch, annotate and animate without breaking flow.

Transparent Overlay Drawing
Draw directly over your desktop with a transparent overlay, making it easy to sketch over reference images, videos, game engines, documents or live software.
It feels more like drawing on glass than opening a heavy editor, so rough ideas and feedback notes can happen immediately.
Frame-Based Animation
Milenko Sketch includes frame-based animation tools for stepping through frames one by one, enabling onion skin and previewing motion.
It is useful for animators roughing out timing passes, blocking movement or quickly testing motion ideas before moving into heavier software.
Brushes, Layers and Palettes
The app supports stylus pressure, custom PNG brush shapes with alpha, and layers for foreground, midground and background.
Quick palettes, including a custom palette file, keep colour selection fast while leaving the main workspace clear.
Export Your Work
Export still drawings as PNG files or turn animation frames into animated GIFs for quick sharing, review or planning.
The export tools are designed for quick iteration, so you can capture rough ideas without turning the process into a production pipeline.
Stay Out of the Way
Frameless mode, full screen mode and instant interface hiding help keep the tool lightweight while you work over other content.
Simple keyboard controls keep common actions close: transparency, palette visibility and playback are quick toggles rather than menu hunts.
Built for Fast Visual Thinking
Milenko Sketch is suited to rough animation, storyboarding, game development sketch passes, live teaching, paint overs, feedback sessions and fast planning.
It gives you a lightweight drawing layer over whatever you are already looking at, which keeps the idea moving instead of forcing a context switch.
