The alarm that won't reset.
Immune and nervous systems stuck switched on, defending against a world that already passed.
Merlin brings bloodwork, imaging, genetics, body composition, gut work, sleep, nutrition, movement, fertility, neuropsychiatric, and spirituality into one continuous portrait of a single body.
The friend who pores over your labs before your appointment, so you walk in asking the right questions.
Three minutes. No account needed. See how your physiology actually behaves before any lab gets uploaded.
Start the 3-minute Archetype quizYour Archetype
Before any of the eleven surfaces, your Archetype - the way your physiology tends to lose its balance. Take the 3-minute quiz to find yours.
How it works
01
Every panel you've had. Every imaging report. Your raw genotype if you have it. Gut work, hormone draws, the symptoms you've been tracking yourself. Merlin reads what's there. No additional testing required.
02
Across systems. Across years. Across providers. You get a system-level read (cardiovascular, metabolic, gut, hormonal, immune), the cross-system synthesis, the questions worth asking your physician, and a prioritized action plan with mechanism behind every recommendation.
03
With your doctor, with your FM practitioner, with yourself. As new data comes in, the read keeps getting sharper. Merlin learns the shape of your body over time.
The Archetype quiz reads your physiology first. Every panel you upload after gets read through that lens.

What follows is a real Cardiovascular surface from a real anonymized panel. The narrative, the score, the layers underneath: this is the output, not a designed approximation.
A detailed look at the factors influencing your Cardiovascular score.
Cardiovascular
FairApoB sits at 117 mg/dL and LDL particle number at 2181 nmol/L - both above the threshold where the conversation about familial hypercholesterolemia stops being academic. The protective markers are real and worth crediting: triglycerides at 69, hsCRP at 0.4, Lp(a) at 17, ApoB/A1 ratio at 0.75, and Pattern A morphology with peak size at 222.9 Angstrom.
...continues with the wall-engagement pivot (OxLDL + Lp-PLA2), the upstream physiology (ApoE 3/4 + Apo C1), and the low-cost levers (Vit D + Omega-3).
A question to sit with
When you look at your typical week of eating, where is the saturated fat actually coming from - and is the pattern something you've consciously chosen, or something that's defaulted into place around your schedule? The ApoE 3/4 genotype makes this a higher-leverage question than it would be for someone else.
Plus the score breakdown, possible root causes, physician questions, supplement plan, imaging to consider, and discussion prompts.

The model underneath
We're building Merlin on the art-gallery model. A working gallery lets you walk in, wander, and sit with whatever catches you — your first full read is on the house. You pay only when you want the ongoing relationship: every new panel read in context, the portals kept current, the synthesis that deepens as your story does.
The deep work — the ongoing analysis and synthesis — costs real money to run, and we price it to cover that, not to fund expansion. But the door itself is free, by design: to undo the assumption that deep self-understanding belongs only to those who can afford concierge medicine, and to leave it open for anyone curious about their own body.
For physicians
The practitioner program is available upon request — built to run alongside your practice, not over it. Patient-owned data, cross-system pattern reads, mechanism-anchored physician-question prompts surfaced from every panel.
