Is it broken?
I tried adding https://github.com/torvalds/linux and asking it to write a simple kernel module for me, but it gave me this error:
"Something went wrong, please try again later. If the problem persists, please contact us."
Edit: looks like it is, I see it's making a POST request to https://gptduck-production.up.railway.app/query which responds with a 500 Internal Server Error when I use a URL that looks like a GitHub repository (whether it actually exists or not), and "invalid repo" otherwise.
