Learn how to use entityOS & AI Services
In this example the node app (as entityOS user) is looking for conversation (set by UUID/GUID in the event..json) that it is a participant in, for posts that have a subject containing @genai or @heyocto. It then passes the message to the GenAI service (in this example OpenAI) and then saves the response as a comment to the original post.
Example uses OpenAI, but you can change to any service you wish.
You can also change to a Python app - using https://github.com/ibcom-lab/entityos-learn-python as your starting point.
