Claude Duet, OpenAI dots, Grok Bot, and Meta Muse Compared: From AI Assistants to 'Always-On AI Employees,' How Will the 2026 Competition Change Everything?

OpenAI announced dots at DevDay on September 29, 2026. Dots runs on GPT‑6 Astra (released September 3) and provides each user with a dedicated cloud computer, a browser, and plugins for more than 4,000 apps. It integrates with ChatGPT, Slack and Teams, and initially allows one dot per person, with future plans for multiple dots and higher work quotas. Actions that affect external systems require user confirmation or an “Auto‑review” safety check.

xAI’s Grok Bot entered beta on August 11, 2026. Users assign a name and responsibility to each bot, which shares a single cloud PC, browser, file system, and terminal. The service supports inter‑bot messaging, task handoffs, and the creation of reusable “Skills” from demonstrated procedures. Meta’s Muse, launched September 8, 2026, runs on the Muse Spark model inside a Secure VM, is free for basic use in the U.S. on iOS, Android, web and WhatsApp, and offers paid plans for heavy users. Muse is not yet available in Japan, and its integrations include Walmart, Best Buy, Instacart, Notion and GitHub.
