About this extension
Keep Claude beside the page you are reading so you can ask questions without copy-paste or extra tabs.

What you can do
- Summarize long articles and docs
- Explain complex topics or code
- Translate foreign-language pages
- Fact-check claims as you read
- Draft emails or notes from the page

The sidebar stays open while you browse. You need a Claude.ai account (free or paid). Conversations go directly between you and Anthropic.
