Products that do what Mathpad – Physical keypad for typing math symbols does
Here's something different than your usual fare: A physical keypad that lets you directly type math! Ever tried typing mathematical equations in your code IDE, email, or on Slack? You might know it can be tricky. Mathpad solves this with dedicated keys for Greek letters, calculus symbols, and more. Press the ∫ key and get ∫, in any application that accepts text. It uses Unicode composition, so it works everywhere: Browsers, chat apps, code editors, Word, you name it. Basically, anywhere you can type text, Mathpad lets you type mathematics. I built Mathpad after getting frustrated with the…

Hi HN It also supports percentages, dates and variables. I've been working on this alone for a few years now, so would love to get some feedback.

Hi HN, I’m the creator of Math2Tex. I was a PhD student, I spend a huge amount of my time working with LaTeX, especially when dealing with lecture notes, academic papers, and homework. I built *Math2Tex*, a lightweight tool that converts handwritten or printed academic content — especially math formulas — into LaTeX or text The Problem: I've always found it incredibly tedious to manually type out mathematical formulas, especially complex, multi-line equations from my handwritten notes or from a textbook. It's slow, boring, and I always make syntax errors. I tried some existing tools, but…

Hello. Briefly about Structpad: All interaction with app comes down to simple typing, like in a notepad. No buttons, commands or special characters needed. However, you can still build complex structured data. Something about why I'm building Structpad: I love taking notes and I think it's necessary for deep thinking because our brain is very powerful, but it has one weakness - memory. I noticed that not only the text itself matters, but also some invisible structure in our minds. There are various tools that try to reveal this structure, such as filenames, folders, tags, links, tables of…

A new calculator software cannot really bring attention (https://chachatelier.fr/chalk/) However, I wrote a full article explaining why I had to build something "new" that does not behave like usual desktop calculator softwares : TL;DR All "small" calculator softwares I know share the same design flaws. And the GUI is not the only stumbling block in their poor efficiency. Handling correctly numerical approximations - expected or not - is crucial to trust the results. It is usually not done in lightweight tools. It should. So I prove that if I could do it, OS manufacturers…

I'm building an online text-editor editor to write and save scientific documents fast. Here's a video of how it works: https://youtu.be/Hyk8CvCdEWE As an engineering student, I hated that handwriting was the only viable way to do fast or impromptu scientific writing. It would be the only way to take quick notes in class or in a lab, write an assignment, or create a presentation. Here's a few things I witnessed in academia: * Unsuitable editors: Students attempt to resort to text editors unoptimized for science, such as Notion or Word, to take notes and write assignments. *…
