Annotate user interface

Picture this: you’re in the middle of a presentation, teaching a class, or walking a colleague through a design, and you need to point out something on your screen—fast. Enter Annotate, a free, open-source macOS tool that transforms your screen into a canvas for instant markups.

With a tap of a hotkey, you can draw arrows, highlight text, or drop numbered steps, all without breaking your flow. Built for speed and simplicity, this lightweight app is keyboard-driven, fully customizable, and packed with just the right tools to make your ideas pop.

Whether you’re a teacher circling key points, a designer sketching feedback, or a remote worker guiding a team, Annotate slips seamlessly into your workflow. It’s not bloated software—it’s a nimble, native Mac app that stays out of your way until you need it, then delivers with precision.

Why You’ll Love It
