What happened
Anthropic launched Duet, a standalone mobile app limited to the US, offered as a research preview
Why it matters
It puts Anthropic into the personal-assistant race, though the preview means rough edges are likely, per the newsletter
Summaries like this, every morning.
The newsletter frames Duet as Anthropic's entry into the personal agent/assistant race, a category where several assistants are already competing. By releasing it as a separate mobile app in research preview and limiting it to the US, Anthropic appears to be testing the product with a narrow group before a wider rollout. The author expects it to be fairly capable but with rough edges, similar to other assistants at this stage.
The same issue notes adjacent developments: OpenAI helped researchers find vulnerabilities in PHP and Railway, and there is a shift toward agents that can operate real Android and iPhones, often called phone use. Those items suggest the tools and security questions around personal agents are moving alongside product launches like Duet.
