Microsoft launched Copilot Cowork, a new M365 feature built directly on Anthropic's Claude that runs tasks in the background across your emails, meetings, and files — available inside a new $99 enterprise tier. Plus, a16z drops its sixth consumer AI Top 100 report showing ChatGPT still dominates but Claude and Gemini are closing the gap fast, and a community workflow from a reader who used AI to prep for a year-end promotion.
