Giorgiokatr As per the current availability of chatgpt models through Azure OpenAI fine tuning allows you to use your data to train a GPT-3 model. However, due to resource limitations fine tuning is not available or turned off for subscriptions who have access to Azure OpenAI. This will change in the future as the service constraints are relaxed.
If you do not have access to Azure OpenAI you can apply for one or use the Azure language service along with custom question answering to create a chatbot which can create KBs of your documents and deploy a chatbot. This however might not be interactive as chatgpt.
