Understand any article with context, related reading and a topic-tuned chatbot
See how the piece you are reading is structured and what else has been written about the same subject, without leaving the page.
Ask follow-up questions of an assistant fine-tuned for the topic in view, rather than a general-purpose model with no context.
A timeline of other outlets that covered the same story, useful for tracing how a narrative developed.
Relevant keywords are connected to common knowledge bases so you can jump from the article to background material.

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.
