Why I Built This
Whether I was reporting a bug, sharing an API issue with a frontend/backend teammate, or these days asking an LLM to "take a look at why this request responds the way it does," I kept repeating the same tedious chore every time.
Open the Network panel in Chrome DevTools, click the request in question, find and copy the headers I need from the Headers tab, switch to the Payload tab to copy the request body, switch to the Response tab to copy the response body, and then reassemble all of it into readable Markdown. DevTools does offer features like "Copy as cURL" or "Copy Response," but they never give me the exact combination I actually want in one shot (e.g., status code + a few specific headers + body only).
