Claude Duet: the cloud daemon behind the personal AI pitch

Claude Duet is being sold as the personal AI that finally shows up for you. Based on Opus 5.5, always ready, quietly handling your work while you live your life. Put it next to OpenAI’s Dots and Meta’s Muse and it looks like Silicon Valley just entered the Her era overnight. Look closer at the April source-code leak, the billing rules, and the permission docs, though, and a different picture appears. This is less cyber companion and more carefully engineered product strategy, and the start of workers losing their last real off-switch. 1/ The leaked Conway process just graduated. Duet is basically a high-end cloud version of OpenClaw. Don’t let the warm “personal AI” branding distract you. The background daemon that surfaced in Anthropic’s April leak is the same core that powers Duet today. Hobbyists used to run OpenClaw on a local Mac mini, fighting sleep modes and flaky tunnels. The official version simply gives you a cloud VM with its own browser and wires it to more than 6,000 connectors. Even the OpenClaw team showed up in the comments to congratulate them. The “personal agent” is, at bottom, a computer that never turns off. 2/ The compute math is the real product. Anthropic waited to ship this because keeping a cloud machine warm burns ordinary CPU and storage, and the margins on reselling that capacity are thin. So Duet doesn’t get its own free compute pool. It draws straight from your existing Claude Pro or Max quota. To keep the servers (and your allowance) from melting, it only checks in every few hours. Those background scans of your email and Slack still count against your limits even when you haven’t spoken to it. Want to truly hand things off? The practical answer is to move up to Max. 3/ Model routing and the black-box browser. Duet is described as powered by the cheaper-to-run Opus 5.5, but the fine print is careful: Opus 5.5 supplies the “judgment”, the part that decides what is worth interrupting you about. The high-frequency, unglamorous work can sit on lighter models. Anthropic quietly released a low-cost Haiku 5.5 not long ago. Meanwhile, OpenAI’s Dots lets you open the cloud computer screen and watch what it’s doing. Duet’s browser is currently opaque. You don’t see the clicks. 4/ The safety rails are real, and tightly scoped. Anthropic carried over the managed-agent approach from Claude Code. Credentials stay isolated; the model never sees your plaintext passwords. An auto-mode classifier sits in front of web actions to blunt prompt injection. Sending email, moving money, or deleting files still requires an explicit approval prompt. Trading and cross-account transfers are hard-blocked. Even if you tap “approve,” the system refuses. 5/ A personal product that looks a lot like a B2B funnel. Unlike Meta’s Muse, which leans into bookings and personal errands, Anthropic has been clear that Duet is built for work and is weak at consumer chores. Yet the preview is open only to individual Pro and Max accounts; Team and Enterprise plans are left out for now. The sequence is easy to read: employees connect company Gmail, Slack, and QuickBooks on their personal plans and get the productivity win. Once managers notice sensitive context living inside those private agents, the enterprise tier can arrive with a new name and a higher price. The underlying container stays the same. 6/ The last good excuse disappears. Always-on cloud agents are technically impressive. For anyone with a job, they also remove the cleanest remaining boundary. “I didn’t bring my laptop.” “I can’t open the file on my phone.” “I’m not on the network.” Those lines lose force when your VM, your connectors, and your context stay online. A message at 11 p.m. asking for a revenue forecast no longer requires you to be at a desk. You can stay where you are and tell Duet to handle it. The technology is polished. The implied schedule is less so. If you want to see the actual flow, how it keeps moving after you put the phone down and then surfaces an approval, the official Claude Duet demo video shows the interaction clearly.
