Claude in Sidebar is a Firefox extension that integrates AI capabilities directly into your browsing experience. This tool allows users to interact with an AI assistant without the need to switch tabs or copy and paste content.

The sidebar remains visible, enabling users to read and chat simultaneously, making it easier to draft emails or notes based on the content of the current page. To utilize this tool, users must create a Claude.ai account, which can be free or paid, ensuring a direct conversation with the AI while maintaining privacy.
