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.

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.

You need an approved email account to use it, so please write here if you would live to try it out.

Solo-built app just passed a bigger competitor on Google Play visibility score https://preview.redd.it/cmy3haru6veh1.png?width=1510&format=png&auto=webp&s=6c9f05bd5d22a012f123e4c4f6f26d1a7c85c5e3 Sharing this because it's a small win but it's mine. I'm the solo dev behind skillably, a study app where you upload your own notes or PDFs and it turns them into quizzes and flashcards, adapting based on what you actually get wrong. No team, no funding, built around a day job.
