This is a glimpse of what the future UI layer for coding agents might look like
This is a glimpse of what the future UI layer for coding agents might look like
working at a YC startup >> All three of these got their first check from YC
JetBrains is no longer behind. @firebender_com just launched the first-ever background coding agents for all JetBrains IDEs. These coding agents are incredibly intelligent, have isolated workspaces, and don’t require any cloud setup.
I wish macOS would show internet speed here or somewhere else very glanceable. (Why do I have to run "speed tests" all the time?!)
A great place for founders to operate is the intersection of [would be really valuable] and [doesn’t quite work yet]. B/c it will work soon.

Biggest update I’ve ever shared… @CreateWithBloom raised $3.4M to unlock the creator economy for software. Let’s be honest: web apps are easy, but building and sharing mobile apps sucks - XCode builds, Apple Developer reviews, TestFlight invites… all make going from idea to…

---If you're in marketing, watch and read, THIS IS GETTING WILD.--- To make this a year ago would have cost six figures at least. It would have also required countless meetings, planning, production, days of shooting, and editing. This took me ~2 hours, and cost me maybe $100…
In a world that’s changing fast, experience becomes less important and young founders gain an advantage.

Being a good PM is hard. I've learned a lot over 12 years as a PM at Google. I wrote down 8 things I learned the hard way, so you don't have to. From shipping fast to being a good friend and yearning for the vast and endless sea, some advice for product managers:
Biggest interaction gap for AI assistants: they still can’t see my screen, let me point at things with my finger, or let me sketch on top of it like a whiteboard.
Fun fact: @typingwala and I started working on @simstudioai 3 weeks before applying to YC. We applied an hour before the deadline on a whim. We couldn’t believe it when we got in. These stories are more common than you think. Go apply! @ycombinator

It will soon be a violation of the Hippocratic oath to not use AI in healthcare.
9 years to get to $10M ARR; 9 months to $100M+. Replit is a story of a founder with a vision finally unlocked by AI.

One thing I'm certain of is that Legora is going to be one of the generational applied AI companies. Today is the time to join the team.
