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.
Unroll X (Twitter) threads into one clean, readable page
Paste an X (Twitter) post or thread link and read the entire thread on one page without signing up.
Switch to Paper Mode for a distraction-free layout with adjustable font size and spacing.
Create a free account to bookmark threads and access your reading list across devices.
