Clinical judgment AI can follow.

LLMs give AI a voice. Maya gives it clinical judgment you can sign off on. Over more than a decade, MayaMD has built its own method for capturing how clinicians decide and turning that judgment into logic machines can execute. It is the foundation under everything we build, not a wrapper around a language model.

An original model of clinical reasoning

Built to reason the way clinicians do.

Maya is not a symptom checker. It is a general model of how experts decide, with two engines that match the two ways clinicians reason, plus the rules each institution adds on top. Every conclusion carries its reference.

CLEAR PATHS

Branching clinical algorithms

Chains of questions and answers where conditions can combine several answers, age and sex, medications, history, location and the institution. Scores add points per answer and map the total to risk bands. Crisp rules give the same answer every time.

FUZZY JUDGMENT

Evidence, weighed like a clinician

Each symptom links to its possible causes, 416 for chest pain alone, each with a prevalence class, age and sex rules and a pretest probability. Each finding shifts the odds: pressure-like chest pain makes coronary disease more likely, and absent findings make it less likely.

YOUR PROTOCOLS

Institutional logic, versioned and auditable

Each organization's thresholds and escalation rules become explicit logic it owns, cited to the source. Built for version control, so it's clear which logic applied when.

Not an LLM wrapper

The language model talks. Maya decides.

Language models are fluent, but they improvise. Given a protocol, they treat it as a suggestion. In the Maya Engine, decisions come from approved clinical logic with a source behind every step. The LLM asks and explains.

Next step

The next question or the right care pathway

The model never chooses the clinical path. Every decision traces to an approved rule and its source.

Why LLMs alone fall short

The agent talks well. Nobody can sign off on how it decides.

Every organization deploying AI agents hits the same wall. Four gaps cause it, and prompts or document search fix none of them.

Not repeatable

The same case can get a different answer on a different day, or after a model update.

Not your institution's logic

A hospital's sepsis pathway or a clinic's triage rules live in PDFs and in senior people's heads. Pasted into a prompt, they become a suggestion, not a rule.

Not auditable

After a bad outcome, nobody can show which rule fired, which source it came from or which version was live that day.

Not calibrated

A model can't say how likely each possibility is in a way an expert would stand behind. It sounds confident whether it is right or wrong.

The usual fixes treat symptoms. Retrieval finds the right paragraph but still lets the model interpret it. Fine-tuning bakes knowledge in where nobody can inspect or update it. Output filters block bad answers but don't produce good decisions. And even a perfect model can't prove which approved rule it followed.

Inside the engine

AI drafts the logic. Experts approve it. Maya runs it. The LLM just talks.

Guidelines, institutional protocols, payer policies and expert walk-throughs become structured, executable pathways. A complex pre-op pathway took about four hours to build. The engine already holds 400+ clinical algorithms, evidence rules that weigh every finding, and translation tables for about 20 languages, and every new pathway reuses that shared vocabulary, so each one is faster to build than the last.

( 01 )

AI drafts the logic

Questions, branches, scores and evidence weights are drafted from the source, with a citation on every step.

( 02 )

Clinicians approve it

A clinician reviews the pathway as readable logic before it runs, and every decision traces back to the rule that produced it.

( 03 )

One logic, inside and outside your walls

The same approved logic guides case managers, nurses and MAs step by step, and reaches patients through voice, two-way text and outreach.

Guardrails against hallucination

Structured logic, not prompts

Protocols live as explicit questions, branches, scores and rules, not as text in a prompt the model can reinterpret. The LLM asks and explains; the decision comes from that logic.

Constrained choices

Where judgment is required, the model can choose only among the options the logic allows. It cannot invent a new path.

Fixed safety rules

Red-flag symptoms always trigger urgent pathways, and no patient is ever directed to no care.

Traceable decisions

Every decision traces to the rule that produced it and the source behind that rule, so there is nothing to take on faith.

Why it matters

Why healthcare organizations need an engine, not just a model.

Clinical criteria and triage protocols have been licensed for decades as content people read. None of it is logic an AI can execute, customize to your institution and audit. Maya is that layer: a system of record for how your organization decides, used by every AI tool you deploy.

Consistent care on every shift

The same protocol is often applied differently by each nurse, shift and site. Executable logic delivers it the same way to every patient.

AI you can actually deploy

Organizations want AI to scale their teams but can't let a model improvise clinical decisions. Their own protocols, made executable, become the guardrails.

Ready when guidelines change

Update a protocol once and it changes for every team and every channel, with a clear record of which logic applied when.

Expertise that scales without headcount

Your best clinicians' judgment reaches every patient by phone, text and outreach, without adding staff in a nursing shortage.

Built for value-based care

Readmissions, penalties and shared savings depend on reliably delivering what works. Consistency is the business model.

Explainable by design

The EU AI Act calls for documentation, logging and human oversight of high-risk AI, FDA guidance favors decision support whose basis clinicians can review, and CMS requires payers to give specific reasons for prior authorization denials. Explainable logic meets all three; an LLM alone can't.
