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.

Bring ChatGPT into any web page with a shortcut-driven sidebar and selection menu.
Open an OpenAI-powered chat panel over the page you are browsing using a keyboard shortcut, so you never lose context.
Highlight text to summarise, simplify, translate, check grammar, or change length from a floating toolbar under the selection.
Save your own instructions as reusable prompts and trigger them from the quick menu in one click.
Connect a personal OpenAI key for full control over the account, model choice and usage costs.
