 > [!IMPORTANT]
-> In respect to chatbot's Terms of Use, a prompt autofill is all the extension does automatically. Furthermore, the _Apply response_ button placed under responses is not a means of automatic output extraction, it's an alias for the original _copy to clipboard_ button. Review the [content script](https://github.com/robertpiosik/CodeWebChat/blob/dev/apps/browser/src/content-scripts/send-prompt-content-script/send-prompt-content-script.ts) for implementation details.
