Dia: a browser that lets you chat with your tabs and gets better with every single tab you open.
We poured a ton of heart into Dia to get to this moment, now it’s time to get back to making and shaping this thing alongside you all in public.
Couldn’t be prouder, let’s go!

Even though we believe AI has an undeniable place in the future of work, there’s no substitute for the feeling and result of creating with your own hands. So we shot this practically, against a hand-painted backdrop.
Tara Jane Feener retweeted
Yesterday, we launched a new brand identity for Dia with this video, along with an updated homepage, icon, and certain in-app surfaces.
I'm so proud of what this team has accomplished, and the feeling that our new brand evokes. It's one of calm, peace, and optimism 🧘

Today, the beginning of a refreshed brand lands in Dia, painted by hand, to give you warmer, brighter, better days.

We @diabrowser are hiring Prompt Engineers!
Slop cannon. Vibecoder. Prototyper. Product Eng. PM.
We don’t know what to call this role exactly. The official title is the Model Behavior team, We previously called it the Prompt Engineering team, but widened to cover more areas since we move around so much.
It’s a job that changes every week and you get to make up, as you define and build the frontier of technology
We have 2 roles
- One is more Engineering focused
This is not an average engineering role, you will be focused more on designing and building early ideas & quick prototypes. Working with many teams across the company. You should be comfortable independently shipping production features end-to-end in enterprise scale codebases. You'll live at bleeding edge of AI, prompting, harness design, tools, MCPs, memory, evals, and pushing towards whatever comes next.
- One is more Product focused, and open to other backgrounds.
We hire all sorts of creatives, artists, designers & technologists at BCNY. I encourage you to apply even if you don't consider yourself “technical staff” or don't fit traditional tech company roles exactly.
We are looking to build a team of the best Prompters in the world.
If you enjoy tinkering with AI all day, come join us as we reinvent the internet and modern work!
You'll be working closely alongside myself and @jonathan_jlo, our leadership team @tfeener @jedimody , @hursh , @joshm and many others

If you have ever wondered why it took so long to bring spaces to Dia, here’s the full story why:

Massive shoutout to the folks working on Windows, it's come a HUGEEEEE way since when we first were bootstrapping it!
Tara Jane Feener retweeted
We’ve quietly been testing @diabrowser for Windows with hundreds of people. Now ready to open it up more broadly!
We’ll also be updating on Windows progress every Wednesday. More info on all of the above here 👇

Really enjoyed talking to @ridd_design. He creates such a comfortable conversation and I feel like this interview represents me and my positions better than anything else I've done.
I've anticipated this week's @charliedeets episode for over a year 😇
He talks about designing Safari vs. Arc. vs. Dia
We go deep into his personal design principles
And he even takes us on a little tour of some of his favorite craft details in Dia 👇

I think the future of design is simply being able to repeatedly make more successful decisions. Being aware of the weaknesses in your decision-making is the quickest way to increase the rate of good decisions.
From my chat with @ridd_design.

“the browser is effortless context.”
Fantastic interview with @charliedeets showing the intense craft, thought and insight that go into making something truly amazing in @diabrowser.
Packed full of nuggets, it shows the depth of the @Atlassian design team's work 👏🏻

one of my favorite uses of @diabrowser is to ask it to look at my bookmarked tweets and build an interactive page explaining how it relates to my current projects
Tara Jane Feener retweeted
Wow, was I wrong.
I was choked when I heard OpenAI was discontinuing Atlas.
I just setup @diabrowser from @browsercompany.
Atlas now feels like a joke by comparison. Super impressed.
Tara Jane Feener retweeted
Prototyping as Leadership. A great talk by @hursh at @aiDotEngineer how managers need to have a maker schedule.
It’s tough to communicate intuition if you’re not close to the materials yourself.
Feel very fortunate to be colleagues with BCNY and learn from them!

I'm heading to the @aiDotEngineer World Fair this week in SF! If you're around, please come say hi. Let’s grab a coffee and talk about what you're building!

The morning brief from Dia is one of the best AI features I use, and a great example of how an AI native browser can do things that other modalities can’t. Try it!

"i’ve spent many hours and many iterations on the prompt that powers this teeny-tiny sentence."
This is what taste, craft & care applied to prompt engineering looks like
and we are shipping it every week in @diabrowser
there’s a small caption included in every morning brief that quietly became a fan favorite. when we were first prototyping this feature internally, i wanted to create a sense of ease before jumping straight into your work day. so i pulled from one of my favorite moments of the day: walking into our brooklyn office and catching up with my work besties
sadly LLMs don’t know this feeling, so i’ve spent many hours and many iterations on the prompt that powers this teeny-tiny sentence. everything in the morning brief starts with how we believe mornings should feel. if one of these captions can crack a smile, that’s a win in my book!
here’s a shortlist of my favorite examples included in this prompt:
- “nothing on the books until noon. main character energy."
- “light friday. this is what dreams are made of."
- “meeting-heavy day, but hey, at least you're popular."
