For those of you who are in the medical/education side of things, consider using Notebooklm.google.com. I have found this to be a wonderful tool to help create mind maps, study guides, summarize long articles [journal articles], and will even create a podcast based on whatever you upload. I have used it a fair amount, and so far it hasn't hallucinated on me. I believe the reason for that is that it relies on your uploaded documents as its knowledge base- I'm almost certain it is buffing up its LLM based on your uploads and interactions. The screenshot shows what types of uploads it will take.
