The place to learn any topic, quickly
Hi HN, we’re building deriveit.org, the website where you can learn any topic, quickly. On our website, you pay to ask any physics, computer science, or math question, and our community competes to give you the best explanation (for a cash reward). Right now, resources with high quality content are a time drain (papers, textbooks, and courses). We think that material is typically written in an unnecessarily hard-to-read way, but that there are tons of people who are passionate about explaining it well to others. We want to give the world access to those people, and remove barriers for them…
The place to learn any topic, quickly launched on July 26, 2023 with 9 votes, #1,657 of 4,347 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.

all alternatives →- IMI made a cheap alternative to college-level math & physics tutoring2024 · ▲391
Hi everyone! I’m the founder of Explanations (https://explanations.app). I’m building a website where students can get college level math & physics help for 1/10th the cost of private tutoring. You’d type a question, and your teacher replies by drawing a Youtube/KhanAcademy-style video; and this happens asynchronously throughout the week. When I was studying at MIT, I often had to wait 40-60 minutes in line just to get 5 minutes of “help” from a TA - when I needed 1-2 hours. I understood that TAs can’t spend all their time helping me. That’s understandable. But what made…
- IWI wished for a site with a growing list of math problems, I built it2024 · teachyourselfmath.app · ▲384
Good math problems are hidden inside textbooks and online documents. To keep up with all the sources in the world is hard. For someone who just wants to continuously solve problems, finding and going through all the sources feels like a hassle. I wished for a website that could just dump all the math problems available in the world out there. And if I could filter the problems by topics, that would be beautiful. teachyourselfmath is a side project that was born out of this need. At its core, it is a math PDF extraction engine. The engine has some machine learning going on behind the scenes…

- LOLearnawesome.org – Open-source learning map for humanity2020 · ▲216
Hello HN, Over the last 12 months, I have been building https://learnawesome.org This idea came from Danny Hillis' 2012 talk at OSCON, which itself was inspired from Neal Stepehenson's _The Diamond Age : A Young Lady's Illustrated Primer_ The dream is to build a tool that matches the right learning material to the right student at the right time. Wikipedia is great, but it doesn't do a good job of leveraging the rich variety of learning resources that exist on the Web. Same applies to GoodReads - which is focused only on books, whereas these days we actually learn from videos,…
- HUHelp us curate the web’s best content for learning programming & design2012 · beta.whatispolymath.com · ▲49
Link here: http://beta.whatispolymath.com Despite all the educational material on the web, I found it pretty hard to learn how to code and design. I had trouble finding high-quality content, figuring out what to learn next, and staying motivated without easy ways to track my progress. So, my co-founder and I built Polymath. Our MVP is pretty simple right now: you can find & submit good content, bookmark & track your progress across different resources, and rate/comment on the material. We’re trying to build a really fun online learning community, and we’ve got some more cool features…
- LOLearnawesome.org – Discover the best learning resources on any topic2019 · ▲22
Hi HN, Over past few months, some of us had been collecting links to learning resources (courses, interactive explorables, books, podcasts, apps, forums, livestreams etc) in a GitHub repository of markdown files. Since we also wanted to have features like advanced search ("Show me podcasts on machine learning which are entertaining and less than 40 minutes long"), we felt the need for an app. Give it a try: https://learnawesome.org You can think of LearnAwesome.org as a GoodReads-equivalent tool generalized to links to ALL media (not just books). Some features you might like: -…

I saw this [0] pretty cool thread by user revskill, and wanted a quicker way to search through it, but also to keep them all in one place so I can read them at my leisure whenever I get time. Right now is like 60 lines of Ruby using Nokogiri, but I will certainly look into it further down the line and improve the list. There's a cronjob checking the thread every 12 hours but I will eventually shut that down and it will become static after that. There are some really awesome blogs in there. I really recommend going through the list, it made my day. [0] "Could you share your personal blog…
