I seem to have rss.chat running on my Raspberry Pi. Not very stable at the moment. Needed a bit of help from chatGPT joining the dns, apache virtual hosts & ports up. I got as far as locally, then locally network by myself. I had to ask questions to get the rest in order.
It seems quite a good way to do things, using a free account. I run out of questions and then take a break. This allows me to do some thinking myself, I might learn something.
I've also tested the API running bash scripts from TextMate. Posting, editing & delete have worked.
