Working with HTTP messages in Burp Repeater - Port Swigger
Summary: PortSwigger's documentation describes Burp Repeater as a tool for manipulating and resending individual HTTP requests and analyzing the application's responses, with notes that can be added to each tab to manage work. The page also covers Professional-only features such as custom action scripts that extract, transform, and analyze request and response data, manual issue creation for reports, and built-in Burp AI with Explainer for AI-generated explanations of selected message parts.
Bottom line: Repeater now runs AI prompts against any tab and generates explanations of headers, cookies, and JavaScript, so request and response data - including anything sensitive captured in a session - can be sent to a model from inside the testing workflow.
