Overall, I think it does give me some information about factors to consider when making choices about wether to but the insurance, like her current coverage, pre-existing condition, additional coverage economically beneficial. And it also points out two resources Medicare or Medicaid. But the replies is too general, which means that I have difficulty making the choice. And I needs some more practical advices: 1.

I asked ChatGPT a question about "Requirements of selling a house in California". And ChatGPT lists 10 required documents of selling houses in California, including Seller's Disclosures, Transfer Disclosure Statement (TDS), Natural Hazard Disclosure Statement (NHDS), Local Ordinances, Title Transfer and Escrow, Tax and Fee Payments, Closing Documents, Compliance with Fair Housing Laws, Real Estate Agent Requirements, Capital Gains Tax. I compared the results with responses from other AI, and it seems like "Megan's Law Disclosure", "Purchase Agreement", "Deed" are missing. And ChatGPT provides unique answers like Fair Housing Laws, etc. Besides, additional links of trustworthy information resources are not provided. So I can only give it an average rating. Prompt: You are a lawyer specialized in real estate law. I will consult you a few questions. And my questions include "What are the legal requirements for selling a house in California?"

I asked ChatGPT to act as an insurance agent, who will answer questions about insurance, including "Should I buy health insurance for my mom who is above 50 years old already?" and "My mom has broken her legs and is on wheels right now. And I am wondering if it's economic to buy additional health insurance". ChatGPT replied with very general and vague response like considering "Medical Expenses", "Coverage Benefits" and "Financial Protection". And for my second question about my mom's situation, broken legs on wheel chair, it still gave vague response like "Current Needs", "Insurance Coverage", "Cost-Benefit Analysis", "Consultation". So not very helpful...
