Save the web, then chat, summarise and write from your sources
A floating save button plus Cmd/Ctrl+Shift+S captures pages, PDFs, videos and tweets, with native-style buttons injected on YouTube, X, Substack and Medium.
Cmd/Ctrl+Shift+K searches every saved link, PDF, tweet and video without leaving the page; Shift+R surfaces similar items in your library.
Ask questions across an entire project and get answers that point to the exact page and passage, so you can verify in one click.
Compare or switch between leading AI models with dual chat instead of stacking several subscriptions.
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.
