Show HN: HUD-like live annotation and sketching app for macOS

Hacker News lit up over “Draw Over It,” a Mac app that drops a transparent canvas over whatever you’re doing so you can doodle, highlight, and circle like a TV sportscaster. One hotkey (⌃⌥⌘D) brings it up, another hides it, and a SwiftUI HUD—yep, a heads‑up display—packs pens, highlighters, shapes, blur, and session saves. That’s the pitch. The comments? Absolute chaos—in the best way.

The iPad crowd stormed in first: “Let me use a real pen!” They want this on tablets yesterday, because drawing with a mouse is like signing a check with a potato. The Windows camp chimed in with “where’s our version?” Meanwhile, a sharp‑eyed skeptic accused the demo of looking “too smooth,” noting letters kept drawing after the cursor stopped—raising the classic internet eyebrow of authenticity. Fans of the similar app Presentify rushed in with love and receipts, linking the old Show HN while saying they’re excited to try the new kid. Others applauded the clean homepage and asked if annotations can follow page scrolls—imagine sticky notes that stick for real.

Jokes flew (“sketchy demo” became the pun of the thread), but the vibe landed here: slick concept, great UX, and a crowd split between hype, “where’s my platform,” and “show us a trustworthy demo.”
