SF rent is insane. Good listings disappear within hours. So I built a @browserbase Function that wakes up before me, hunts SF apartments on Craigslist, and drops the best listings in my inbox every morning. Here's how I built it 👇

Anyone else tired of paying more than $25 for a halloween costume they'll only wear once? I was, so I made an agent that finds the cheapest one (that's still in good condition ofc) Will never manually online shop again with this deal-bot in my back pocket 🤖 🛍️

Morgan Stanley, Chase, BofA, and more are now blocking AI agents because they can't tell if the customer sent the agent. But the fix isn't banning agents, it's agents who prove who they are and never see your password. Here's what that looks like 👇

Your agents are only as good as their context, and the most valuable context is often locked behind a login. Introducing Authenticated Fetch, 1 request to instantly extract data from logged-in sites. It’s 3x faster than a full browser session, and available on all plans today.

Everyone’s debating whether websites should block AI agents. The real question: how does a site even know who’s knocking? 🔐 Here’s Web Bot Auth explained in less than 100 seconds 👇

Why is GPT-6 Astra so much faster at computer use than other models? A big part of it is the accessibility tree: the same thing screen readers use. It's easier for a model to read than a screenshot, and it uses fewer tokens. Full breakdown 👇

Tech’s biggest fight right now: should AI agents get the same access to the web that you do?

The people who refuse to use AI because of its water consumption but would never even consider being a vegetarian…. Your thinking is flawed. Your 10lb steak was ~18k gallons of water, your one AI prompt was 5-7 drops of water. Make it make sense.
