Time to make math suck a little less!
The Booth brothers (@J4mesBooth & @MaxB00th) are building Chiron: an iPad app that understands math as it’s written - like Grammarly for algebra. Using symbolic logic to track your thinking in real-time, they’re making human-quality AI tutors a reality. ycombinator.com/launches/Nb0-c…
This moment from WWDC 2013 when Craig Federighi poked fun at Bump was a not-insignificant motivation I carried for years to make sure Google Photos continually smoked Apple Photos. And it's nice hearing ppl still call it "bumping" on their copycat, more than a decade later.

Advice to ios developers - make your app internationally available from the get go!

i was first money in @J4mesBooth’s project chiron in 2023 - YC is so well-deserved. it’s been incredible watching james grow as a founder, but he’s been remarkably consistent in one sense: he never looks so at home as when he’s in a math classroom!

AI requires a complete redesign of the products we use. @koomen joined us to talk through how builders should think about this.
Super slick UX - definitely recommend if on macOS
Willow (@WillowVoiceAI) is the future of voice-first computing. Thousands of people have replaced their keyboards with Willow to get emails, docs, and AI prompting workflows done 4x faster. Congrats on the launch, @_allanguo and @LiuLawrence45!
Coming from England, where maths courses at 16 and 18 became much more rigorous, I can’t believe what’s happening here. I’d never have fallen in love with math without an amazing teacher who pushed us, in a curriculum that let him. That took me from public school to Oxford to…
