What is an AI assistant?
An AI assistant is a language-model tool that helps you get things done — answering questions, drafting and summarizing, planning, and increasingly taking actions like managing email, calendars, and documents. Some are general helpers, others are built into a specific app or your device.

- Works across email, calendar, docs, and apps
- Voice and text input, on desktop and mobile
- Memory of your context and preferences

How does an AI assistant work?
An AI assistant sits on a language model and adds context about you — your prompt, past chats, and connected apps like email or calendar — to give relevant help. Newer assistants can also take actions through integrations, moving from answering questions to completing tasks for you.
