We sit between the evidence and the decision

About synlayer

Pronounced SIN-lay-er. From syn, to put together, and layer: a layer that synthesizes, sitting between the guideline and the clinician.

synlayer builds the evidence layer for clinical judgment. We don't build foundation models and we don't write guidelines. We sit between them: reading what a clinician already has, synthesizing the evidence that applies, and citing every line.

We started with two problems that look different and are shaped the same. Rare diseases are rare to each physician but common together, and patients wait years for a name. Neurodevelopmental interventions are many to each family but hard to compare, and children spend years in programs nobody measures. In both, the knowledge exists; it just doesn't reach the moment of decision.

Cense brings that knowledge to the rare-disease case in front of a physician. Grovera brings it to the intervention plan in front of a clinician and a family. One engine, two products, the same promise: no citation, no claim.

How we work

We give an opinion, with its basisOur products say consider, supports and argues against. Diagnosis and care decisions stay with clinicians and, in Grovera, with families.

We state evidence at its gradeGuideline-recommended, limited evidence, evidence uncertain. We don't call anything proven, and we say when we don't know.

We publish numbers with their testAny performance figure we share names the evaluation set, its size and its date.

We stay independentSponsors fund content upkeep, never content. Independent experts review every pack, products are never named, and sponsorship is disclosed.
