Meta upgrades its AI chatbot with calendar and deep research features

Meta is adding calendar integration, daily briefings, and steerable in-depth research to its AI chatbot, powered by the new Muse Spark 1.1 model. The company frames the update as a step toward a more assistant-like AI product.

Why it matters: Meta is chasing Gemini, ChatGPT, and Claude's move toward proactive personal-assistant features rather than pure chat. With Gemini nearing a billion monthly users, the assistant category is becoming the main battleground among the major AI labs.
