Interactive linear algebra tutor where you solve matrix problems with real-time AI hints.
u/CarefulArmadillo3496 · Reddit
SparkGap - an agentic linear algebra experience Hey everyone, I'm building sparkgap.ai , an interactive tutor for linear algebra. You fill in the matrices/vectors, the LLM gives you hints until you get it correct. The hope is that it will get smarter over time from the context of which questions were missed/answered correctly. As you master concepts, the progress ring next to each concept will slowly fill in. Hopefully it should be very difficult to get to full mastery. Feedback and qu

Solve math problems and collaborate with peers using AI assistance.

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.

Explore countries' economic data on an interactive 3D globe and play geography games.
u/Pecherskymikel11 · Reddit
I built an explorable 3D globe of the world economy – click any country, get its economy, or play 18 geography games. 10 weeks, zero runtime API calls globenomics.world — spin a 3D globe, click any country, and get its actual economy: GDP, wages, inflation, its biggest companies, and exactly where it ranks against every other country on 34 metrics. Then there are 18 geography games built on the same data — including one where you name as many countries as you can in three minutes, and one

Measure objects in photos by setting one known reference size.
@Laxman101058405 · X
A few days ago I needed to measure something from a photo. Instead of searching for the perfect tool, I thought: "Why not build it?" So over the next 2 days, I built a Photo Measurement Tool using Cursor. If you try it, I'd love to know what you think.

Guess historical figures from their birth/death dates and map locations in a daily game.
u/data_guy_123_123 · Reddit
Geography/History game: LifeGuessr! Hi all! I worked over the last 3 months on this game: lifeguessr.com The concept is very simple: you get a birthdate, a deathdate (if relevant), and a map, and your goal is to identify the historical figure these details pertain to. Multiple hints are available to make it a bit more fun I have expended it to a wide collection of figures, including contemporary ones. I also had a bit of fun with some custom themes, rewards, etc. This game is comple
