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.

Adds an Explain control to the specification document so you can request an explanation without switching tabs or tools.
Uses Google's PaLM AI to convert formal spec algorithms into readable, step-by-step descriptions.
Tuned for the ECMAScript specification, turning dense algorithmic text into something a developer can follow quickly.
