Add-on Canned Responses

I am looking for canned responses for specified nodes, and only specified user groups are allowed to create them and use them. If there is already something that can do this please let me know, as i have been looking for a few weeks and have not seen anything that is what I am looking for.
There is an addon that does it.
If you detail your attempts to find it. I'll try and find it too.

There is no node specific one I don't think
Thank you for your response. I have attempted to search for it here by searching in the search tab for canned responses, thread reply templates, etc. as well as searching on google. I have yet to find one. We need the responses to be per node or category as they will be different for each..
