AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.

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.
