Comparison

Where Merlin fits, and where the others stop short.

First, a real anonymized panel that Function ran but never connected to its obvious clinical implications. Then an honest map of how every major platform in this space differs - Function, Lifeforce, InsideTracker, Superpower, and where Merlin sits in relation to them.

HIPAA-handled
Your data never trains anyone's model
Provider-shareable reports

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.

Actual panel · anonymized

A 39-year-old male. Function ran the panel. LDL-C 195. ApoE4 noted. Hyperlipidemia flagged. Familial hypercholesterolemia: never raised or connected.

This sat alongside significant food sensitivities to wheat, casein, and egg white - all staples in this individual's diet. Function never asked about his symptoms, his goals, or anything that would push him to explore these. A note that he had some high levels and important findings, yes - but it arrived weeks after the panel resulted, and the onus to return and apply any of it was left solely on him.

What Function showed

Hyperlipidemia noted. ApoE4 heterozygosity noted. Total cholesterol 281. LDL-C 195. The summary directed the reader to “consider lifestyle modifications” and “discuss with your physician.” No urgency. No FH possibility raised. No cardiology referral suggested. At 39 with LDL-C 195 and ApoE4 heterozygosity, the standard differential includes familial hypercholesterolemia. The summary the patient received didn't mention it.

What Merlin surfaced

LDL-C at 195 with ApoE4 heterozygosity at 39 is a textbook familial hypercholesterolemia suspicion. Merlin says it. The pattern around it sharpens further: ApoB 131, Lp-PLA2 145 (vascular-specific inflammation already declaring itself), OxLDL drifting up. But the HDL efflux capacity is still intact at 11.9%, hs-CRP is 0.4, homocysteine is 7.7. This is a young man at familial-tier LDL who hasn't yet accrued systemic damage. The intervention window is wide. The reader walks into the next visit with the FH question explicit, the labs worth ordering (Lp(a), CAC scan), and the priority order. Not a diagnosis. The conversation that should have happened on day one.

The landscape

Where each platform fits.

Every platform in this space gets something right, and the field is improving fast - Function's clinician notes in particular have stepped up considerably in 2026. Here is an honest map of where each fits and where Merlin overlaps versus where it does something different. None of these are either-or with Merlin; the synthesis layer reads whatever panels you already have, no matter who ran them.

Function Health

~$499 / year

Best for

Comprehensive twice-yearly panels with substantive clinician-style synthesis.

Function generates both the data and the read. As of mid-2026, their clinician notes have leveled up considerably - per-system narratives with marker-level reasoning, trend analysis across consecutive draws, mechanistic explanation (LDL particles to oxidation to hs-CRP, TRT to erythropoiesis to polycythemia), genetic suspicion flagged where the phenotype suggests it (MTHFR for rising homocysteine despite B-vitamin supplementation), and integration of medical history into the read (medications, lifestyle, prior symptoms). It is no longer accurate to characterize this as a flat AI summary - the synthesis within a Function panel and across consecutive Function draws is real clinical reasoning.

Where Merlin differs

The ceiling at Function is your Function panels plus what Function asked about at intake. Merlin's synthesis extends across any panel from any source - your last physician's blood work, your raw genome from 23andMe or AncestryDNA at the SNP level (not just phenotypic suspicion), the DEXA imaging report from last year, your gut microbiome from elsewhere - and across surfaces Function does not test: imaging-derived musculoskeletal, gut barrier function, fertility beyond hormones, neuropsychiatric beyond cortisol, and a contemplative-inquiry layer (covenant, archetypal mapping, purpose synthesis) that no comparable platform attempts. Use Merlin on top of Function: the Function clinician notes get richer in context, not replaced.

Lifeforce

~$199 / month

Best for

Concierge bio-optimization with a hormone-replacement lens.

Performance physician + health coach + quarterly panel draws. The model is premium clinical-concierge: a clinician relationship, optimization protocols, often hormone-forward. Strong if you want a clinician overseeing your data with a performance bias and the bandwidth to call you back.

Where Merlin differs

Lifeforce is a clinical service; Merlin is a synthesis layer. You can stay with your Lifeforce team and use Merlin to read your panels across years and systems - including the surfaces Lifeforce doesn't focus on (gut, fertility, neuropsychiatric, musculoskeletal). The two don't have to be either-or.

InsideTracker

~$249 - $589 per panel

Best for

Athletes optimizing performance via dietary intervention.

Algorithm-based recommendations with a nutrition and lifestyle lens. Strong in the athletic-performance community, good at producing actionable next-step lists for diet, supplements, and training load. The action plans are concrete and the science behind the nutrition recommendations is well-curated.

Where Merlin differs

InsideTracker uses an algorithm tuned for nutrition. Merlin uses an LLM tuned to a functional-medicine clinician's reading. The synthesis covers more than blood - genetics, imaging, body composition, gut, fertility - and the voice is closer to a clinician than a nutrition coach.

Superpower

~$499 + monthly

Best for

The Function model with a heavier AI-forward marketing layer.

Newer entrant in the comprehensive-panel category. Similar twice-yearly panel-subscription structure with more emphasis on AI-driven insight in product positioning. The execution covers a similar comprehensive draw with an interactive AI overlay on top.

Where Merlin differs

Superpower's AI summarizes Superpower's panels. Merlin's synthesis works across any panel from any source - and reads them as one continuous story rather than a series of snapshots. The product is the read, not the panel.

Best for

Anyone with panels they haven't been able to make sense of - and the contemplative dimension to sit alongside the clinical read.

LLM-driven synthesis tuned to a functional-medicine clinician's voice. Cross-system reads across blood, imaging, genetics (at the SNP level), body composition, gut, musculoskeletal, fertility, and neuropsychiatric - plus a contemplative-inquiry layer (covenant, archetypal mapping, purpose synthesis) that sits alongside the clinical read. Practitioner-friendly. No required panel purchase: it reads whatever you already have. The art-gallery model - free entry, browse, sit, pay extra when something earns a place on your wall.

Pricing approximate as of writing. Each platform's product evolves rapidly - Function's clinician notes have improved substantively since 2025, and the others are iterating too. If anything here is out of date, the underlying structural distinction (cross-source synthesis, surface breadth beyond blood) still holds.

The read that catches a pattern like that starts before the panel. The Archetype quiz reads your physiology first - three minutes, no upload.
