Summary
Riley Brown shares what he learned from roughly ten hours using Anthropic’s new Claude Duet, a standalone agent app for iOS and the web that is powered by Opus 5.5 and positioned against Muse, Grokbot, and OpenAI’s Dots. Unlike OpenAI’s approach of embedding Dots inside ChatGPT, Anthropic ships Duet as its own app, currently in early access.
The video walks through the interface and how work is organized. Rather than a mascot-style bot, Duet uses Slack-like channels, such as content and finances, with a main agent that delegates requests to the right channel. Each task spawns its own thread, and outputs appear as artifacts in a Make tab. Brown demonstrates dictating a request on his phone that adds a slide to a presentation, with the change syncing in real time to the web app. He also has Duet build a Q4 predictions slide deck by studying his past videos, showing how task progress is tracked and reported back in the main chat.
Viewers get a practical look at Duet’s layout, voice dictation, task and artifact handling, and the quirks of its thread structure, along with how it compares to other agent apps.
