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.

Find any page you've visited or bookmarked by describing it, not its URL
Query your history and bookmarks with a topic, phrase or rough memory instead of an exact URL or page title.
Visited pages and bookmarks are indexed as vector embeddings, so fuzzy queries still surface the right article or page.
Find saved pages by what they are about rather than hunting through folders and titles.
Pair two browsers with a single code to move history and bookmarks across machines — no login or account required.
