Anthropic Launches Always-On Personal Agent Claude Duet

On October 22, Anthropic released Claude Duet, an always-on personal agent, currently available as a research preview. Dan Shipper, founder of Every and tech writer, along with his team got early hands-on access for two weeks and publicly called Duet the first personal agent he considers worthy of being called a "professional tool," with an overall verdict of impressed. The most visible change is usage habits: he went from "basically all ChatGPT" to splitting his time 50/50 between ChatGPT and Claude, making it the first product to genuinely take away his ChatGPT usage time in the personal assistant scenario.

Confirmed

Anthropic released the always-on personal agent Claude Duet as a research preview.
Dan Shipper and his team tested the product for two weeks ahead of launch and published an in-depth review.
The core of Shipper's assessment: Duet is the first personal agent worthy of being called a "professional tool."
After testing, his usage split shifted from ChatGPT-dominant to an even 50/50 between ChatGPT and Claude.

Why it matters

Personal agents are widely seen as the next form of AI products, but most previous offerings stayed at the demo level. Shipper, a heavy ChatGPT user, shifting his attention is a signal that a personal agent has for the first time taken real attention away from ChatGPT in sustained real-world use, a landmark moment for the competitive landscape of the personal assistant space.
