I have been using chatnode quite a lot these days, testing its capabilities.

My main use for now is to train different academic bots that help me explore different topics and even related topics but from specific perspectives that I want to be sure are kept separated.

So I have a bot with information about an inmense ammount of statistical techniques, a bot about an specific paper I wanted to understand despite not being good with mathematical notation, a different bot with the manual for some photography software, and so on.

I have achieved desired results by progressively refining the system prompt I set for each chatbot. Through those prompts, I give precise instructions about when I want them to be more rigid thinking and when I want to give them more freedom to generate insights and such based on the documents I uploaded.

I have also tested if they bots get to be actually restricted from the general knowledge they have been trained on and take only the uploaded documents into account. I achieved that by asking something I'm sure is not part of the documents and refining the system prompt a couple of times until it didn't resort to that ex machina knowledge.

I find having a fixed ammount of tokens each month something that keeps the exercise stress-free. I know if I somehow run out of tokens, I can simply pay for more at will, but I'm quite relaxed knowing the won't be undesirable billing surprises in any case.

I can see there is room for improvement, for sure. For example, right now I'm not able to resume a past chat. It is just stored in chat history (which i think should be browseable through a friendlier and more advanced mechanism), but I cannot interact with said history. Ideally, I would like to be able to pick up some chat wherever I left it.

Also, I would like to have a better way to communicate fix requests, support requests and suggestions than just being able to send an email to the developers.

Overall, I think it is a great product that is thinking long term and that implies to carefully build and control their costs structure. I think they will last and, therefore, my investment will have been a good one.
