Convert handwritten math notes to editable LaTeX and PDFs.
u/Worth_Difference_282 · Reddit
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

Interactive 3D visualization showing step-by-step derivation of Euler's identity e^{iπ} + 1 = 0.

I built my first app with Grok Build and had a lot of fun making it. It’s a little interactive lab for e^{iπ}+1=0. You start at 1, turn halfway around the circle, land on −1, then add 1 — and you can actually see why the equation works. Code: Any feedback is appreciated

Free, accurate online calculators and practical guides for finance, math, health, construction, engineering, and everyday life.

I'm building CoreToolLab, a free utility site with calculators for finance, health, education and everyday decisions. We're trying to make each tool genuinely useful rather than just another basic calculator.

Type a math problem and get step-by-step walkthroughs with explanations.

MathIQ I built mathiq.io with Claude Code because I wanted a way for students struggling with college level maths to see how the problems can be broken down and not as intimidating. Each walkthrough goes from beginning to end and each step has a "why and how?" feature. Anon users get 1 free daily walkthrough powered by Haiku 4.5. Signed in users get 3 free daily walkthroughts powered by Haiku 4.5. Plus users get 5 Opus 4.6 walkthroughs plus 20 Sonnet 4.6. Pro users get 8 Opus/30

Hi HN, This is ProofTree, and in TLDR: it is a platform where you can chat with an AI to do math, the way you already do, with context-awareness and knows how you personally do math, connected to the fora of other live human mathematicians. So, when you are talking to an AI about a proof at 3 am, and you need a human expert looking at it, or a discussion around it, like you do on StackExchange, this is it! You need an approved email account to use it, so please write here if you would live to try it out.

做了一个免费的 Concrete Calculator,帮 DIY 用户估算混凝土用量 最近做了一个英文站:The Concrete Calculator 地址: https://the-concrete-calculator.com 它主要解决一个很具体的问题:用户在做 patio 、shed base 、walkway 、slab 这类小型混凝土项目时,不知道该 买多少混凝土、多少袋,或者该订多少 cubic yards 。 目前支持: - Concrete Slab Calculator - Concrete Pad Calculator - Concrete Yard Calculator - Concrete Bag Calculator - waste factor - cubic yards / cubic feet / cubic meters - 简单材料成本估算 做这个站的原因是我发现很多英文混凝土计算器要么广告太重,要么结果不够直观。这个版本尽量把核心计算和 单

Built a free tool site to help my brother study — now has 100+ tools, would love feedback My brother's in high school and needed something more visual to study chemistry, physics, and math, so I used Claude to build him a simple site with interactive calculators and visualizers. I'm not a programmer or from a tech background, so without AI this wouldn't have happened, at least not this fast. It ended up helping him a lot more than I expected, so I kept expanding it, added a bunch of other
