XNote is a free Chrome add-on designed for X/Twitter users, allowing them to enhance their social media experience by adding personal notes and organizing users with customizable tags. This tool enables users to remember details about their connections, which is particularly useful for content creators and researchers. With features such as color-coded groups, quick search functionality, and the ability to backup and restore data in JSON format, XNote offers an efficient way to manage relationships on the platform.

The add-on supports 15 languages and ensures user privacy by storing all data locally in the browser without requiring an account or tracking. Users can easily manage their notes through a side panel view, making it convenient to navigate without leaving the main X/Twitter interface. While the free version includes generous limits, users have the option to upgrade to Pro for unlimited notes and cloud synchronization.
