Psychiatric assessment hasn't scaled with the need.
The bottleneck isn't demand — it's specialist capacity. The numbers describe a structural gap, not a marketing angle.

Limbus is building clinician-led AI infrastructure for psychiatric assessment — designed to conduct structured assessment at scale and hand clinicians a psychiatrist-reviewed report. The aim is to widen access to assessment without lowering the bar on clinical rigor.
Built by a practicing psychiatrist, Limbus is a specialist-built system — not a wellness app and not an autonomous diagnostic engine. A human clinician stays in the loop on every case by design.
The platform
One platform, from assessment to therapy.
Limbus Health is clinical AI infrastructure for mental health — two products in one clinician-supervised pipeline. A clinician stays in the loop at every step.
From referral to report — without the wait.
A structured psychiatric assessment pathway — designed around 10 standardized instruments and Bayesian reasoning across 22 conditions, with every report reviewed by a psychiatrist before it reaches the referring physician.
See how Assess worksEvidence-based therapy. Guided by AI. Overseen by your clinician.
Evidence-based psychotherapy — beginning with ERP for OCD and extending to IPT, CBT, and ACT — designed for delivery with real-time clinician oversight and progress tracking, so care can continue without a gap after assessment.
Follow our progressLimbus Assess · How it works
A guided assessment pathway — reviewed by a psychiatrist.
Limbus Assess is in development. It is designed to support clinicians through a structured assessment pathway — not to make autonomous diagnoses.
- 01
Guided intake
A person completes a structured, plain-language intake at their own pace — capturing history, context, and presenting concerns.
- 02
Structured screening
Validated screening instruments are administered systematically, with built-in validity and safety checks rather than a single questionnaire.
- 03
AI-led clinical interview
A structured interview gathers the detail a clinician would ask for — following established assessment frameworks, not improvising.
- 04
Psychiatrist-reviewed report
A psychiatrist reviews the assembled evidence and the draft formulation. Every case is reviewed by a clinician before any diagnosis is finalized.
Human in the loop, by design. The AI assembles and structures evidence; a psychiatrist makes the clinical call. Limbus is intended to give clinicians better-organized information — never to replace their judgment.
Clinical credibility
Rigor is the product, not a feature.
Limbus is being built to clinical standards from the inside out. These are design principles for a device still in development — not claims of clinical performance.
Bayesian-rigorous reasoning
Assessment is treated as evidence accumulation, not pattern-matching. Findings update a structured clinical picture rather than producing a black-box label.
Validity & safety gates
Built-in checks flag inconsistent responses, risk indicators, and cases that fall outside intended scope — surfacing them for clinician attention.
Every case psychiatrist-reviewed
No diagnosis is finalized without a psychiatrist reviewing the evidence and formulation. The clinician owns the clinical decision.
Conservative by design
Where evidence is uncertain, Limbus is built to say so — and to defer to the reviewing clinician rather than over-claim.

The founder
Dr. Marie Claire Bourque
MD, FRCPC
Psychiatrist · Founder of Limbus
A psychiatrist building the infrastructure she wished existed.
Dr. Marie Claire Bourque is a Royal College–certified psychiatrist practicing in British Columbia. She has spent her career on the front line of the access gap — in emergency departments, on inpatient wards, and in outpatient assessment, where the wait for specialist care is measured in months.
Limbus grew out of that work. Rather than wait for the system to train its way out of a shortage, she set out to build clinician-led infrastructure that brings structure and rigor to assessment — and is writing the system herself, pairing clinical judgment with the engineering to deliver it.
"The goal isn't to take the psychiatrist out of the room. It's to make sure the room exists — and that the clinician walks in with the evidence already organized."
Questions
Answers for everyone reading this page.
For clinicians
Does Limbus make diagnoses on its own?
No. Limbus assembles and structures assessment evidence and drafts a formulation; a psychiatrist reviews every case before any diagnosis is finalized. It is designed to support clinical judgment, not to replace it.
Is Limbus authorized for clinical use?
Not yet. Limbus is a software medical device in development, with a Health Canada Class-C filing pending. It is not currently licensed for clinical use.
How does it stay rigorous?
Through validated structured instruments, built-in validity and safety gates, Bayesian-rigorous reasoning, and mandatory psychiatrist review of every case.
For patients & families
Can I use Limbus now?
Not yet — Limbus is in development. You can join the waitlist to be notified as it moves toward availability.
Will Limbus diagnose me?
No. Limbus is designed to support a clinician’s assessment, with a psychiatrist reviewing the evidence. It is not an autonomous diagnostic tool and is not a substitute for care from your own clinician.
