Big step from Apple in opening up agentic experiences on iOS IMO, they've been slower to ship first-class AI features natively that really push the boundaries...which makes sense given their massive user base This is a huge opportunity for consumer founders on mobile

Today, we’re kicking off the Highlight beta. Try it here: go.highlightai.com/highlight… I want a future where AI helps make your work uniquely yours, and not feel cookie cutter. That’s what we’re building Highlight for. Highlight is your working world, all in one place. It connects your apps, meetings, and screen, creating a single command center where you can find answers, see what needs your attention, and start every task with the first draft already done.

If you would like to witness genius, watch and listen to this.
Being an exceptionally talented musician is one thing. But to stand before such high-caliber fellow musicians, a large audience, and cameras—all while remaining composed, communicating skillfully and effectively, showing genuine enjoyment, and staying focused on the creative process—that is what truly amazes me.

fitting those cameras inside the pen for your tutor-on-the-go
Lately I’ve been learning math with ChatGPT (Astra) as my tutor, using this document scanning camera and a vibecoded tool that pastes the captured image right into the chat. This way, I just work problems on paper and ChatGPT gives feedback. It’s really nice.

This Meta Glasses commercial at the US Open was absolutely brilliant. At the end of the day, your phone might just stay in your pocket. $META is coming for your lunch, $AAPL. Watch out.

The guys who made RAM so expensive are singing their hearts out to “Uptown Funk.” Look how happy they are. 😂 Made on two DGX Sparks using MiniMax H3.
