Anthropic Unveils Claude Duet Proactive AI App for Business Owners

AI research firm Anthropic introduced Claude Duet, a dedicated application preview built to operate as an autonomous background assistant for professionals. Powered by the Opus 5.5 model architecture, the application integrates with business email, calendars, and document hubs to handle administrative tasks without direct human supervision.

Unlike traditional chat-driven systems, the software reverses user dynamics by proactively alerting users via morning briefs and pending action items. The launch establishes a direct product defense against rival tools, targeting small business operations looking to delegate invoice tracking and scheduling.
