absolutely loved building this space. more improvements are on the way!

Today we're launching Claude Duet in research preview.

It's a new app from @AnthropicAI where Claude works as your always-on, proactive agent. It tells you what needs your attention and what can wait, and it keeps working after you've put your phone down. You always have the final say: it asks before it sends, pays or signs.

What I didn't expect to be writing about today: we've been building Duet with Duet.

For weeks I've been leading the project from the app. A tester's note comes in, I hand it over from my phone, and what comes back is what it found, what it changed, and the one decision that's actually mine. My Claude Code sessions, the Slack threads I'm following and the tasks I've handed off all sit in the same place, so I can see what needs me without opening a laptop.

The night before launch, I found a visual bug on my phone at 10 PM. I sent a screenshot and two sentences. Before midnight a fix was up for review, with a plain note about the one thing it couldn't verify without a real device.

That note is why I trust it. It says where its work stops and mine begins.

I've been lucky to build this with a wonderful team, from the first prototype to today's launch. A lot of care went into the details, and we hope it shows.

It's still early, and we're looking forward to learning from how people use it.
