Autousers is a free Chrome extension designed to enhance the evaluation process for users participating in the Autousers human evaluation interface. This tool enables seamless side-by-side comparisons of websites by embedding external sites within iframes, which is essential for users to assess and rate candidate websites effectively. When users open an evaluation share link, the extension facilitates the rendering of two candidate websites, allowing for an efficient evaluation experience.

The extension operates by modifying specific response headers that typically prevent iframe embedding, ensuring that both panes display the intended content instead of an error message. It only alters headers for sub-frame requests originating from the Autousers domain and does not affect top-level navigation. Importantly, the extension does not collect or transmit any user data, ensuring privacy and security while enhancing the evaluation process.
