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.
From bookmark clutter to AI-sorted clarity
Sign in with X/Twitter and all your saved tweets are pulled in and kept in your account, ready to browse instantly.
GPT-4 Turbo automatically sorts your bookmarks into clear, meaningful categories, removing the manual sorting grind.
Define your own topics and the model meticulously scans your bookmarks for relevant tweets to fill them.
Export your entire bookmark library in CSV or JSON for backup, migration, or deeper analysis.
