Live in Dia today. Pull requests have new previews with:

• Realtime CI status
• Sharper metadata
• Conflict resolution
• Comment triage (great for bot slop)

Enjoy!

1/ We just launched automatic tab clean-up in @diabrowser. The premise is simple: Your browser should be lighter in the morning than how you left it the night before. The design problem underneath is not.

[christine røde @chrstnerode]

the Morning Brief in @diabrowser is one of my favourite projects we've worked on recently, and today it got a shoutout on stage!

i had a lot of fun designing these — and we've got more in the works 💫📑

[Charlie Deets @charliedeets]

Last week, we shipped a new @diabrowser update to friends and family.

This update is a step change in functionality for Dia and we couldn’t be more excited to see what you make.

You can join the beta today by entering ‘deetsman315’ into a new tab.

Looking for someone to lead Brand Design at @browsercompany.

The ideal candidate views themselves as an artist, doesn’t work in tech, and lets their portfolio speak for itself.

We’ll pay you more than you make now & ask you to design not manage.

Josh @ the browser . company

Out of sight → out of mind → stalled PRs.

Live Tab Groups are here to break that habit.

[dustin senos @dustin]

@mikegee @arcinternet will let the team know. apologies this happening ❤️

[Josh Miller @joshm]

Big news:

Apple’s lead Safari designer just joined @browsercompany.

Alongside @charliedeets, that means we now have the lead designers from every Safari era that overlapped with Arc and Dia (2020 to 2025).

We’re not fucking around this year — 2026 will be our biggest yet 🏀

[dustin senos @dustin]

We’re hiring our first Design Producer at @browsercompany.

You’ll partner with me and help shape how a world-class design team operates.

This isn't a steady-state role. We move at uncanny pace, live in ambiguity, and a constantly update how we work as we learn.

I can’t promise this is an easy role, but I can promise you’ll work with a small, world-class design team that cares deeply about shipping, craft, and each other.

@hugosaintemarie woah! i do, and somehow have never noticed. you’ve saved me so much time. thank you.

[dustin senos @dustin]

i wish that after clicking 'go to main component,' Figma offered a large 'go back to where you were' button.

the effort to reach the source should match the effort to return back to your work.

[dustin senos @dustin]

team is cooking. bringing the best of arc over. rethinking the fundamentals. thursday release notes.

and above all, having a lot of fun building with wonderful folks.

[Alexandra @alexandracoding]

Dia wrote this for me.

[dustin senos @dustin]

excited this one’s out. it collapses the time from idea to valuable skill to near zero.

[Dia @diabrowser]

Complex Skills, simple words.

Create expert-level prompts with the right tools, memory, and context - from just one sentence.

The new Skill Builder is now in Dia!

[Josh Miller @joshm]

Starting today, the @browsercompany is back to shipping weekly updates. October's Dia releases include:

• More powerful memory (of your tabs)
• Redesigned Dia Skills
• Arc's Focus Mode (CMD-S)

All landing in @diabrowser this month. Oh, we removed the waitlist today too 🤗
