Handwritten notes into latex + study tools - looking for feedback Hey everyone, I'm a mathematics student at university, and over the past few months I've been building something called LatexNotes in my free time. The original problem was pretty simple, I like taking paper handwritten maths notes, but whenever I wanted to turn them into proper LaTeX afterwards or to get AI to mark answers, it was a pain. I kept needing to switch between my university’s content platform, then to Chatgpt to e

Free calculators for DIY home projects like woodworking, decks, concrete, and drywall.

Built a DIY calculator site in a weekend — betting on "boring tools" over content After my last project (an AI debate platform) got rejected by AdSense for "low value content," I went the opposite direction: no content treadmill, no AI features, no backend.

Every calculator you'll ever need for money, health, math, and everyday conversions — worked examples included, nothing to sign up for.
