HUD-like live annotation and sketching app for macOS
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…
In plain words
Draw Over It is a macOS app that lets users draw, highlight, and annotate directly over any window or application using a global hotkey. Designed for pair programming, demos, and quick sketching, it provides drawing tools, shapes, and highlighters in a lightweight overlay without requiring system permissions or collecting user data. Annotations can be exported as PNG files with a single click, and all content remains on the user's device.

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!

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
