today I heard a very good trick on this. A IIoT SaaS company puts an LLM in their documentation; As a customer, you can chat with the LLM and ask question about the documentation getting your answer easier. Then using n8n the SaaS company read all the questions asked to the LLM into a rapport and they use that rapport to discuss the roadmap/bugs/difficulties customers have with the product. SaaS said they never got such valuable feedback about their product.
