I think this is a great concept and it works fairly well however:
1. The settings I put in are not reflected in the actual posts.
2. When I submitted a question in the chat about this, I did not receive a response so customer service is a bit lacking.
3. I removed my account and re-added it to see if it would fix the issue and it didn't fix it.
4. The comments it produces are a good start but they all need editing so I would never recommend just setting it to automatic without reviewing them first.
Also, I would like to see the ability to add a few different keywords rather than just 1. It is a bit limiting.
