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.
Translation that follows the conversation, not just the words
Reads the thread before translating, so short answers, dropped pronouns and replies to negative questions are resolved from what came before.
Flags what a literal reading would miss, such as a Japanese polite consideration that hides a soft no, Korean agreement that flips a negative question, or a joke that is actually a complaint.
Converts times with the reader's city named and shows money in the original currency first and the reader's own second.
Keeps daily, weekly and monthly summaries of each channel with the decisions in them, so vague references are resolved with the date, person and outcome.
