01
Clinically precise
Every insight is anchored in mechanism. We name the pathway, cite the biomarker, calibrate the uncertainty. ApoB before LDL-C. Particle count before population averages. Functional optimal ranges, not just pathological cutoffs.
Clinical depth. Human warmth.
Your body tells a story.
We help you read it.
Merlin reads across labs, imaging, genetics, body composition, gut work, fertility, symptoms, and the years that layer them. The synthesis your data has been waiting for.
We don't order your tests. We don't promise a callback. We don't pretend to be your doctor. We're the friend who reads your story before your appointment so you walk in asking the right questions.
Most lab platforms run hundreds of tests, send an AI summary, and call it done. We pick up where they leave off.
Whether your labs came from your physician, your functional-medicine practitioner, or a direct-to-consumer platform like Function or Superpower - the data exists. The real synthesis usually doesn't. Generic recommendations. Half-finished pattern recognition. A few color-coded gauges in place of the conversation the data was actually trying to start. Merlin reads what's already in your panels - across labs, across years, across systems - the way a functional- medicine specialist would, and gives you that conversation back.
Illustrative pattern · synthetic data
A 40-year-old. Family history of cardiovascular disease. ApoE4 heterozygote. The panel was run. The result sat.
What the panel showed
LDL-C borderline. Triglycerides clean. The standard read: keep an eye on it. No ApoB ordered. No Lp(a) ordered. No particle count. The functional inference the data was actually pointing at - a particle-burden cardiovascular phenotype layered on a lipid-receptor variant - never got written down.
What Merlin surfaced
The ApoE4 context shifts the interpretation of every cholesterol marker on the page. The reader walks into the next visit with three specific tests to request and the mechanism to explain why. Not a diagnosis - a more informed conversation than the fifteen-minute slot would otherwise allow.
How Merlin reads a panel
Three things have to be true at once - or the output isn't worth the time it takes to read.
02
Deeply intelligent
A lab panel isn't a list of independent findings. It's a system with mechanistic threads running between markers - thyroid-lipid, omega-3-Lp-PLA2, cortisol-HPG. Merlin reads those threads the way years of clinical practice would.
03
Genuinely empowering
Every insight ends with a physician question. The goal isn't to create dependency on an app - it's to make the next conversation with your doctor sharper. You leave with mechanism in hand, not just a finding.
What Merlin reads
The synthesis layer doesn't just read one kind of data. It reads the conversation between them.
Labs
Every panel you've had, across years, providers, and lab vendors. Functional ranges, pattern across systems, the question your physician should ask next.
Body composition
DEXA, InBody, Bod Pod. Trajectory across scans. Lean mass, regional distribution, vascular age, the parts of your body that aren't fully readable from blood.
Genetics
Causal-SNP interpretation and triangulation from your raw genotype. Serious disease-risk findings opt-in gated, the rest woven into context for everything else Merlin sees.
Gut & microbial
Comprehensive stool and microbiome panels read as pattern, not as a findings list. Phase-1 / Phase-2 / Phase-3 protocol shape rather than "here's what we found."
Fertility & hormones
Cycle phase, hormone rhythm across the day and month, partner workup context. Optional and opt-in.
Cross-system synthesis
The pattern that lives between systems. Inflammation interlocked with sympathetic vigilance. Gut barrier feeding mood drift. Vascular trajectory layered on years of metabolic load. The thing nobody else is reading.
What it costs
Pricing that reflects what's actually here.

Core
$20/month
Unlimited lab uploads and synthesis. Every Merlin surface: biomarker patterns, body composition, vascular phenotype, gut, neuropsych, the R&D portal. Weekly pattern updates. Conversation with Merlin Sage.
Premium
$99/month
Everything in Core. Quarterly deep synthesis across every panel you've uploaded. Genetics interpretation. Concierge intake: your first thirty minutes mapped by hand.
Meet the Magician
$500/quarter
Everything in Premium. A standing quarterly hour with the Merlin clinical team: live interpretation of your patterns, real-time protocol adjustment, the conversation in dialogue rather than in the platform.

What kind of biology are you carrying?
The SFM Archetype is a three-minute profile of how your physiology actually behaves - where it allocates energy, how it responds to stress, what it tends to under-report. It's the lens we use to interpret every panel you upload after. No email required to start.

For physicians
For functional medicine physicians who want a smarter pre-visit read than the EMR gives you.
A practitioner program is in development, 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.
Coming soon
We'll surface the program here when it's ready. Building the thing first.
