Over the last week, our team has been hard at work revamping our security processes from e2e in response to our first major vulnerability. Thank you everyone for your feedback over the last few days. We heard you, and these changes are just the beginning.

Congrats, Ankur Goyal and crew! We couldn’t imagine building reliable and production-ready AI products without Braintrust. Grateful to work with you all!

Arc on Windows is now on ARM! This took a ton of work across compilers, builds, and our windows codebase. Huge props to Steven Brix, Sebastien Marchand, Hiroshi and everyone else who hustled to get this out!

I couldn’t be more honored and grateful to welcome Adam Wiggins to Browser Company! I’ve been a fanboy of Adam’s work for over a decade – he’s thoughtful and composed, has incredible business and technical acumen, and is an all-around lovely human. Excited to work alongside him

Nick is creative, thoughtful, and brings a rare intuition for working with LLMs. We’re lucky to have him on the team and excited to show you what we’ve been building together!

Meet Dia, our new browser! Dia is just getting started, but our vision is simple: software that deeply understands you, helps you focus on what matters, and steps in when you need it most. Can’t wait to show you what’s next!

i'm so excited about this! it opens up a ton of creative possibilities, especially when combined with the other skills.

Loved the skills system of the @Diabrowser and dropped a Skill Gallery for Dia Browser—one-click commands for content, research, and design, all in your browser. Link below.

still can't believe this works and takes 2 mins to set up in Dia built a full-on web agent that goes and does the first pass on qualification for Adaline from a company website within seconds custom skills are going to be 🤯 hats off to the team

new favorite skill in Dia: /every-edit any web page i'm on it can automatically copy edit it according to our internal Every 📧 style guide. this is going to save HOURS

We had quite a therapeutic conversation with Dan Shipper 📧 about Arc, Dia, and our perspective on AI and pivots. Check it out below!

I’ve been evaluating people using my Dia /skill. It’s called /graham and It’s scary good. Watch me test it on a few victims live (incl. Nikita Bier )

Couldn't be more psyched to welcome Josh Miller & Hursh Agrawal and the entire, wonderful The Browser Company team to Atlassian. With Dia, we're going to collectively re-design the browser to help knowledge workers kick ass in the AI era. It's a mission. A joint mission. A huge

We’re joining Atlassian, and I’m deeply grateful. Mike and team truly understand what we’re building with Dia - our ambition, our values, and why we think it will change how people spend their days at work. We’ll take a breath today, then keep going- hire faster, ship faster,

Dia is now generally available on Mac! And we have a ton of fun stuff shipping in the coming days and weeks to make your workday easier. Check it out below!

We're opening a new ai prototyping role at BCNY! Shoot me a DM or apply if you know anyone who'd be interested.

If you’re in NYC, stop by our panel about agentic product engineering on Dec 1! We’d love to say hi!

on top of being intense GEPA users, big surprise from Samir Mody’s talk on the AI engineering behind The Browser Company’s Arc and Dia browsers is they’re intensely aware of Simon Willison’s Lethal Trifecta, and designing their Agentic browser to have security in mind!
