ChatGPT-powered AI right inside any web page
Select any text on a page and trigger an action such as explain, reword, proofread, translate or summarize without leaving the site.
Open a ChatGPT-powered chat box inside the current tab and ask questions or paste prompts while keeping the page's context visible.
The assistant works on the page you are already viewing, which removes the back-and-forth between a website and a separate chatbot tab.
Use it to translate unfamiliar passages or to clean up and restate your own writing in place.
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.
