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.

Enter any English word and receive a batch of example sentences that use it, generated live through the GPT-3 API.
Learn words the way they actually appear in writing, rather than as isolated dictionary entries with a single definition.
Add it to Chrome in one click from the Web Store listing — no sign-up, no account, no payment details required.
The whole extension is roughly 22 KB, so it loads instantly and does not slow the browser down.
