A general-purpose AI agent that executes tasks, not just answers them
Give the agent a goal and it plans the steps, chooses tools, and works through the task in a cloud environment without constant supervision.
Produces finished artifacts such as slide decks, functional websites, small games, and formatted documents rather than raw text.
Runs broad, multi-source investigations and compiles the findings into a structured report.
Generates images, video, and music as part of a larger task or as standalone outputs.

Browser-native LLMs at your fingertips, private and offline
Large language models are packaged inside the extension and executed in an isolated browser sandbox, so no server, account or API key is required to get started.
Every request is served from your own machine, which keeps your prompts and data off third-party servers and lets the tool keep working when you are offline.
Websites and extensions can request access to your model through the window.ai interface, turning the browser into a shared AI runtime for web apps.
You decide which applications are allowed to talk to your model, and you can review the history of prompts and responses made across different apps.
