Rezonant - Alter is a Chrome extension designed to facilitate user feedback on application interfaces. It provides users with a simple tool to suggest alterations, leave comments, and edit copy directly from their browser. By using the extension, users can capture screenshots and details about specific elements, which are then sent securely to their Rezonant team workspace for further action.

The extension emphasizes privacy by only collecting necessary information, such as email addresses for account identification and feedback-related data. Users can feel secure knowing that their browsing history or sensitive information is not tracked. Rezonant - Alter allows for a collaborative approach to application design, enabling teams to refine their user interfaces based on direct user input.
