Pymander vs Function Health: free AI doctor consults vs a $365 lab membership

Last updated September 3, 2026.

Pymander and Function Health both want to catch health problems early, at wildly different price points. Pymander is a free AI doctor you reach by plain text, with access to testing at more than 2,000 lab locations. Function Health is a $365-per-year membership built around a large annual lab panel.

What does each one cost?

Pymander's first AI doctor consult is free: you text an AI doctor, get an assessment, and receive a care note, with no account and no membership. Function Health charges $365 per year, billed annually, which includes its lab panel; it frames this as $1 per day versus a claimed $15,000 out-of-pocket equivalent. Function is a deliberate annual investment. Pymander is a free first step before you decide whether any testing is warranted.

What do you actually get?

Function Health starts you with 160+ lab tests that it says detect signals across more than 1,000 conditions, drawn at home or at more than 2,000 partner labs, with results reviewed and tracked in a dashboard. Pymander starts with a conversation: you text the AI doctor about symptoms, risks, or results you already have, it asks the follow-up questions a careful clinician would ask, and it can route you to testing through its own network of 2,000+ lab locations when labs would actually answer the question. Function tests everyone on a schedule. Pymander helps you decide what is worth testing at all.

Which one should you pick?

If you want a big annual panel and a longevity dashboard and you are happy to pay $365 a year, Function Health delivers that. If you have a symptom, a risk factor, or a stack of old results and you want to know what matters before spending anything, text Pymander for free. Emergencies bypass both: call 911. Pymander routes emergency red flags to 911, and its escalation logic is documented in its safety architecture working paper.

What a Pymander AI doctor consult looks like

You said you want to know which labs are actually worth running given your family history. Who in your family had heart disease, and how old were they?

My dad had a heart attack at 52, and his father had one around the same age. I am 38 and my last physical was two years ago.

Thanks for giving me all this information. Based on what you've said, your family history makes a focused set of labs genuinely worth it, and I will list exactly which ones to ask for. Here's your care note to share with your care team.

Care note

Family history, targeted lab plan

First-degree relative with heart attack at 52. Fasting lipids, A1c, blood pressure check, discussion of further screening. Chest symptoms at any point mean be seen immediately.

Common questions

How much does Function Health cost?

$365 per year, billed annually, per its own site. That includes 160+ lab tests per year at home or at 2,000+ partner labs. Pymander's first AI doctor consult is free.

Does Pymander do lab testing?

Pymander routes members to testing through a network of more than 2,000 lab locations when labs would answer the question, rather than putting everyone on a fixed annual panel. The free part is the AI doctor consult itself.

Is an annual mega-panel worth it?

It depends on your risks. People with a strong family history or unexplained symptoms get real value from broad testing; for others, a targeted panel ordered for a reason is often the better spend. A free Pymander AI doctor consult is one way to think it through.

Do either replace a doctor?

No. Function Health provides testing and a dashboard; Pymander provides AI assessment, care notes, and routing. Abnormal results and diagnosis still need a clinician.

Does Function Health take insurance?

No. It is a cash-pay membership. Pymander never touches insurance either.

What if it is an emergency?

Skip both and call 911. Pymander is built to recognize emergency red flags in your text and direct you to call rather than continue.
