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.
Turn any web page, PDF or email into natural speech you can listen to anywhere
Play any article, newsletter, email thread or web page with a single click, without copying text into a separate app.
Highlight a passage and tap the floating button, or draw a box around a region to hear only that part of the page.
Upload documents straight from your device and listen to reports, papers or ebooks without converting formats.
Follow highlighted subtitles as audio plays and adjust playback anywhere from 0.25x to 4x.
