An AI-powered platform for solving and collaborating on math problems in a social context.
lemma1729 · HN
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.

Block distracting websites by solving math or coding puzzles.
hackitup7 · HN
TLDR built a Chrome site blocker that lets you into distracting sites only after you do some math or simple coding (JS only right now). Direct link to extension (the site just gives you more context): https://chromewebstore.google.com/detail/sphinx-earn-your-di... Philosophically it's a speed bump rather than a hard gate, because you'll eventually tear a gate down but you'll leave a speed bump. I've always eventually removed site blockers, or just had them become a nuisance that I reflexively dismiss before getting to distracting sites. Site blockers don't really reduce the "start navigating to a distracting site" muscle memory, and they eventually just become annoying. Dopamine is a hell of a drug. At the same time, I've been getting frustrated that my intermediate/advanced math skills have atrophied, and becoming more senior in my career (plus AI...) has caused my coding skills to atrophy even further. Realistically I'm not going to force myself to do math or coding exercises aft
