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.

One AI workspace for every kind of writing
Generate marketing copy, social media content, and personalized messages from a short brief in seconds.
Draft professional sales, support, marketing, or networking emails tailored to a specific audience and goal.
Rewrite existing text into a cleaner, more original version while keeping the original meaning intact.
Provide characters, a setting, and a genre, and the generator builds an engaging narrative around them.
