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

https://draw.wrobele.com/
25•tomaszsobota•2h ago
Hey all!

I'm happy to announce we've finally released our 2nd macOS app, Draw Over It, a tiny desktop app that enables drawing, highlighting, or annotating directly on top of anything on your Mac.

I've always wanted something like this for instant and unobtrusive sketching and annotation for pair programming and demos. I always found the standard web-based diagram and drawing tools a bit too cumbersome. So we built a simple overlay that could appear over any window or app with one shortcut.

It doesn't collect any user data and doesn't require any system permissions - it's sandboxed. It all stays on your device. You can export your annotations to a PNG with one click - or just take a screenshot if you need the background too.

It offers a slim but functional toolkit for every day tasks:

- Global hotkeys, hit a shortcut and start drawing over any app

- Multiple tools, pens, shapes, highlighters

- Per-screen canvases, each monitor gets its own space

- Focus mode, temporarily blur the background to emphasize what matters

- Low footprint, no subscriptions, no sign-ups, no data collected

- Localization, the app is translated to 14 languages

These two reasons make it different from other canvas apps, it's simple, lean and keeps your data on-device only.

It’s a one-time purchase ($2.99) on the Mac App Store.

I’d love feedback and suggestions for improvements!

i'd love this for the iPad, i'd buy it right away but didnt see it for the iPad -- mostly because writing with a mouse is very difficult, but pens are easy
tomaszsobota•1h ago
And I'd love to make it for iPads too, just struggling to find the optimal UX for enabling and disabling the overlay.

On macOS you can just use the global hotkey or the app menu, on iPad I'd have to wire it up somehow else - supper happy to get ideas on what would feel seamless and unobtrusive for you. I'll definitely implement it then!

What about a control center toggle? Works alright for toggling the windowing system. In general having shortcuts to set it on/off/toggle would be great.
tomaszsobota•40m ago
This might work! I'll implement this and see how it feels, thanks.

The letters keep drawing after the mouse pointer stops moving. Is there such thing as an autocompleting typeface that recognizes handwriting from a Wacom tablet or something to explain this? If not, this demo doesn't seem authentic and that doesn't inspire confidence.

Hey, thanks for the feedback, the cursor movement is smoothed out in the screen recording tool.

I tried to strike a balance, original videos felt a bit too distracting with unfiltered cursor movements.

I've been a VERY happy customer (no affiliation whatsoever) of Presentify for many years now, which was also a "Show HN" post (yeesh) 5 years ago

https://news.ycombinator.com/item?id=22938604

I am very excited to try Draw Over It—thank you for sharing. I speak at several conferences a year, and also do online workshops and training, and Presentify has been a godsend.

However, the one limitation is if you toggle it, you lose your annotations. And you can't do anything with the underlying app—can't scroll or click buttons. Looking forward to trying this out.
