👋🏼 Overdue update: I joined @AnthropicAI, and excited to finally share what my team and I have been building. Introducing Claude Duet, a new app in research preview where Claude works as your proactive agent. It runs on Opus 5.5, and we built it to be a partner you can trust. It comes to you with what needs your attention, works across 6,000+ connectors and plugins, keeps going when you step away, and checks with you before it acts. We built it for professionals and small business owners juggling a lot at work and at home. Early testers are using it to help run their businesses, take on bigger projects at work, and get time back to be more present. I've been using Claude Duet to build Claude Duet, and it's been the most joyful and meaningful experience of my career. I’ll be sharing regular updates here on how we’re building it, plus new features and improvements as they ship. Follow along. Join the waitlist and help us shape the product: claude.com/product/claude-du…
We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent. It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.

Check out this quick walkthrough from @pablostanley where he shares more about how Tasks (threads & tab) and Channels are at the heart of Claude Duet. It's still early and there's more work to do, but we're excited by the potential of these new primitives for working with proactive agents. If you're off the waitlist and using Claude Duet, we’d love to hear what’s working/not working, and what you’d like to see next.
some of what we've been designing in Claude Duet... a few big ideas, and some tiny details can't wait to see what you make with it join the waitlist: claude.com/product/claude-du…

I have to say, hats off @claudeai for duet. I’ve been using this for a week or so now and i am very much pleased with it. Once finished, there’s really no need to go elsewhere for personal AI. The claude family of tooling is well rounded! I love the concept of channels. It feels like i am talking to somebody in different contexts who still remembers all we were discussing. It just feels natural. I do think having multiple agents would be quite nice though! Further on that “same but different” trajectory, Somehow, the @link integration is so absurdly fast here. Paying for things feels incredible. I do however feel like the “watch the desktop” feature could use some work. Feels like it’s missing that “something”. I also miss desktop. I want a solid duet desktop app so i can pick things up from there as well. Overall, hats off! What a great product and tool.

Day 6 of Claude Duet! A few updates on access, and really appreciate everyone’s patience on the waitlist: - We’re getting all Max users in the US off the waitlist first. Lots of invites went out yesterday and today, with more coming this week. - Right after Max, we’ll start inviting Pro users in the US. - For folks outside the US, we’re working hard on extending access and will share a date as soon as we have one. If you’d like to try Claude Duet and help shape it, please join the waitlist. claude.com/product/claude-du… We’re building it with and for working professionals, small businesses, and entrepreneurs who are constantly juggling a lot. Team is reading every piece of feedback and shipping daily. More soon on how we built Claude Duet, how people are using it, new features and improvements.

Claude duet will have local Mac access! And apparently they only use Opus 5.5. All good news.
Replying to @rileybrown
Really appreciate the feedback. We're working on remote control and local mac access. More to come on that soon! We only use Opus 5.5, so I'd love to hear more about what feels like "Opus 5.5 lite" - examples would help us a lot!

We worked hard on making proactivity high-signal and valuable, love to hear it coming through!
A shout out: had codex answering some emails (fairly routine, I save higher order tasks for opus)…duet comes back to me saying “hey, that conversation you are having and upcoming meeting about a distributor looks like a scam..” It then explained that it had looked up the company licenses and two were fake. The scam is basically they place a big order with us, overpay, ask for refund, but kill their payment before it hits my bank. $30k in this case. Codex (running luna sub agents) oblivious. Duet hitting me up, verifying the scam and then telling me exactly what to do.

We’ve been humbled by the interest in Claude Duet, and are working hard to get people off the waitlist. In the meantime, a few thoughts based on DMs, emails, posts we’ve seen. → Who can use it: Pro and Max subscribers in the US, for now. → Where: You can use it on iOS, Android, and web once you get off the waitlist. Mac app is in the works. → Trust: We designed Claude Duet to be a partner you can trust. More on our safety, security, privacy approach in today’s blog post: claude.com/resources/article… → Use cases: We’re starting with work use cases, which is what a lot of people come to Claude for. Professionals, small business owners, founders, anyone juggling a lot. We’re opening the research preview to these segments first so we can co-build together. Over time, we'll support more use cases across work and life. → Context: Claude Duet already knows about everything you’ve been working on with Claude. Your chats, memory, projects, and more are available in Claude Duet the moment you open it. → Tasks: Tasks are at the center of the experience. Every task gets its own thread you can check in on and steer, so you can multi-task and hand off many things at once. Claude Duet also proactively suggests tasks it can take on, with your approval. We’re glad to see this primitive and dedicated tab resonating. More to come soon. → Proactive with judgment: Opus 5.5 is widely loved for complex real-world work and its natural communication style, and we’ve built around it for deep judgment. More work to be done here so it feels like a world-class teammate, coworker, chief of staff. → Channels: We went with one agent that works across your main chat and dedicated channels, so each area of work gets its own space. Small business owners and professionals are already using channels for customer support, marketing, bookkeeping, etc. Starting next week, we’ll share more on how we built Claude Duet and how early testers are using it. We know usage limits and access outside the US are top of mind too, and are working on both. Please let us know what else we can improve - we're reading all your feedback.

Best sports year I’ve witnessed in decades with the @nyknicks & @Arsenal winning. I’ve been an Arsenal fan for 25 years and it was a dream come true to watch them lift the trophy live and celebrating on the streets of London. I can only imagine what New Yorkers are feeling right now and the city will be electric tonight. Two legendary teams. Nothing brings people together like sports.

The highest form of debate isn't about one person declaring victory. It's about both people making a discovery. The goal isn't to defend your reasons and attack theirs. It's to sharpen your reasoning. Good arguments shift what you think. Great arguments change how you think.

The higher you climb, the more your success depends on making other people successful. Leaders are judged by what their followers achieve. Leadership is elevating individuals to do more than they thought possible and groups to do more than their members could independently.

Why does everyone want to do strategy? What’s really behind execution problems? How is everyone so confident in this meeting? Just a handful of ideas covered in a fun convo with @shreyas, @evanlapointe and @ahuja_karan Highlights 🧵
