Microsoft has announced significant upgrades to its AI-powered Copilot chatbot, marking its 50th anniversary. Copilot can now perform tasks on various websites, including booking tickets and making restaurant reservations. It can remember user preferences and analyze real-time video from users' devices. The chatbot can track online deals and generate podcasts based on content from the web. Additionally, it features a new Deep Research function for complex queries and offers users control over what it remembers. These enhancements aim to keep Copilot competitive against rivals like ChatGPT and Google's Gemini.
