Have AI Research Medicare Advantage vs. Medigap, With Sources
Medicare Open Enrollment runs October 15 to December 7. Instead of wading through mailers, have an AI “deep research” tool spend 10 to 30 minutes reading official sources and write you a plain-English report comparing Medicare Advantage and Medigap for your situation, with links you can check. Then take it to a free Medicare counselor.
Why it's useful
Choosing between Medicare Advantage and Original Medicare with a Medigap plan is one of the biggest money-and-health decisions of retirement, and the mailbox fills up with ads every fall. A deep research tool works differently from regular chat: it reads dozens of web pages, then writes an organized report with the sources listed, so you can see where each claim came from. Used well, it turns a confusing pile of information into a short list of smart questions for a real, unbiased counselor.
What you'll need
💡 Needs: ChatGPT Plus, about $20/month
Deep research is a premium feature. ChatGPT Plus ($20/month) gives you “expanded” deep research; OpenAI doesn't publish an exact number of reports per month. Claude's version (called Research) needs Claude Pro ($20/month, or $17/month billed yearly). Google AI Pro ($19.99/month) gives you more of Gemini's Deep Research.
Free way to try it: Gemini's Deep Research is included on the free plan (with usage limits Google doesn't spell out), and ChatGPT's free plan includes a limited amount of deep research. Either is a fine way to try this once before paying for anything. You'll need to sign in with a free account for both.
How to open deep research
Deep research is a special mode, not the regular chat box. In ChatGPT, sign in, then look in the + menu (or Tools) next to the message box for Deep research. In Gemini, sign in and look under Tools (or Upload & tools) for Deep Research. Menus move around, so if you don't see it, type “How do I start deep research?” into the chat.
Also works in: Gemini Deep Research (free, limited) or Claude Research (Claude Pro).
Step by step
- Jot down your situation, not your identity: your ZIP code (not your street address), your current coverage, the medicines you take, the doctors and hospitals you want to keep, whether you travel or spend winters elsewhere, and a rough monthly budget.
- Open ChatGPT and sign in. (Trying it free? Use Gemini at gemini.google.com and sign in with your Google account.)
- Turn on deep research: click the + or Tools button next to the message box and choose Deep research (Gemini: Deep Research).
- Copy the prompt below with the blue button, paste it in, and fill in the [square brackets].
- Answer its questions. Deep research often asks a few clarifying questions before it starts. Answer them the same way: situation, not identity.
- Go get a cup of coffee. The report usually takes 10 to 30 minutes. You can close the window and come back; it keeps working.
- Read the report and click a few sources. Make sure the important claims point to Medicare.gov, your state's insurance department, or another trustworthy source, and not to a company trying to sell you a plan.
- Take it to a pro before you decide. Bring the report and its questions to your free State Health Insurance Assistance Program (SHIP) counselor (find yours at shiphelp.org) or call 1-800-MEDICARE. Check actual plan prices at Medicare.gov/plan-compare. Changes must be made by December 7.

Please research and write a plain-English report comparing Medicare Advantage with Original Medicare plus a Medigap (Medicare Supplement) plan, for my situation. I am not asking you to choose a specific plan for me. I want to understand the trade-offs so I can talk to a counselor. My situation: - ZIP code / county and state: [e.g., 49506, Kent County, Michigan] - Current coverage: [e.g., Original Medicare + Medigap Plan G + Part D / a Medicare Advantage HMO / new to Medicare] - Medicines I take: [list names, or say "a few common generics"] - Doctors and hospitals I want to keep: [names, or "flexible"] - Health in general terms: [e.g., generally healthy / one chronic condition / frequent specialist visits] - Travel: [e.g., I spend winters in Florida / rarely travel] - Rough budget for premiums and out-of-pocket costs: [e.g., about $250/month] Please include: 1. A one-paragraph bottom line in plain English. 2. A side-by-side table: monthly premiums, out-of-pocket maximums, doctor networks, prior authorization, drug coverage, extra benefits (dental, vision, hearing), and coverage when traveling. 3. What happens if I choose Medicare Advantage now and want to switch to Medigap later, including whether insurers in my state can review my health history or charge more. 4. Key 2027 dates and deadlines. 5. Ten questions I should ask a free SHIP counselor or 1-800-MEDICARE. Rules: Cite sources for every important claim, preferring Medicare.gov, CMS, my state's insurance department, and independent nonprofits like KFF. Don't rely on insurance company or broker sales pages. If something depends on my state's rules or on specific plans in my area, say so instead of guessing. Write for a smart reader who isn't an insurance expert.
What the AI might say back
EXAMPLE ONLY This is a made-up sample to show the kind of answer you'll get. Your answer will be worded differently and based on your own situation.
Bottom line: For someone in Kent County who wants to keep their current doctors, spends winters out of state, and expects regular specialist visits, Original Medicare with Medigap usually costs more each month but brings fewer surprises and works with any doctor who takes Medicare nationwide. Medicare Advantage often has lower premiums and extra benefits, but uses networks and prior authorization, and travel coverage is often limited to emergencies.
The big catch to know about: If you pick Medicare Advantage now and want Medigap later, in most states Medigap insurers can review your health history and charge more or turn you down, outside a few special situations. A few states give extra protections; Michigan's rules are worth confirming with your SHIP counselor. [Source: Medicare.gov, “Get Medigap basics”]
Questions for your counselor: 1. Are my doctors in-network for each Advantage plan I'm considering, for all of 2027? 2. What's the most I could pay out of pocket in a bad year under each option?…
Tips
- Deep research isn't instant. It's built for big questions. For a quick question, regular chat is faster.
- Plan prices and networks change every year. Treat the report's numbers as background, and check real 2027 plan details at Medicare.gov/plan-compare.
- Ask a follow-up in the same chat: “Turn the questions for my counselor into a one-page checklist in large print.”
- Watch out for sales sources. If the report leans on a broker's or insurer's website, ask it to redo that part using Medicare.gov and your state's insurance department.
Privacy note
Never include your Medicare number, Social Security number, birth date, full name, or street address; a ZIP code and a general description of your health are plenty. This report is homework, not advice. AI can be wrong or out of date, and it isn't a licensed counselor. Make the final decision with your SHIP counselor (free and unbiased), 1-800-MEDICARE, or Medicare.gov.
