Draw Over It: macOS app for drawing and annotating directly on screen

What it does

Draw Over It is a macOS application that creates an always-on overlay for drawing, highlighting, and annotating directly on top of any window or application. Users activate the overlay with a keyboard shortcut, sketch or markup content on the floating canvas, then hide it with the same hotkey. The app offers pens, highlighters, shapes like rectangles and circles, blur effects, and erasers. Annotations can be exported as transparent PNGs, and the canvas state persists between sessions or can be manually saved as snapshots.

Who it is for

The app targets presenters, trainers, pair programmers, and professionals who need quick markup capabilities during live sessions. It serves anyone wanting to add annotations to documents, presentations, or codebases without switching applications or using web-based diagram tools.

Pricing

The site does not show prices. The app is available on the Mac App Store, but no pricing information appears on the homepage.

How it stands out

Draw Over It emphasizes simplicity and minimal friction. Instead of launching separate drawing software, users toggle the overlay with a keyboard combination and start annotating immediately. The HUD toolbar appears on right-click and stays within the overlay, eliminating window switching. The app does not collect user data and requires no special system permissions, which contrasts with some competing tools. Export is instant: one click generates a transparent PNG. The app supports macOS 13.5 and later with universal binaries for both Apple Silicon and Intel Macs, and is available in 14 languages.

What a founder should check

A competitor should verify the switching costs: many professionals already use web-based tools like Figma or built-in screenshot markup. The question is whether a dedicated, local-first overlay justifies a new purchase or subscription. Second, confirm the moat around speed and hotkey convenience—this advantage erodes quickly if browsers or other applications add similar overlay features. Third, examine pricing pressure: if the app charges a fee, test whether users will pay rather than use free alternatives like native macOS tools or browser-based annotators. The data-privacy angle may matter to some segments, but it is not clear if this alone drives adoption or switching.
