Give Clinicians Patient Context Memory That Persists Across Every Visit
Clinical AI tools forget patient history the moment a session ends. Clinicians re-load chart context for every new question. MemoryLake gives clinicians an encrypted patient context memory layer — with full provenance and version history — so AI assistance carries the full longitudinal picture into every encounter.

The problem: clinical AI tools see one visit at a time
Yesterday's note mentioned a new allergy. Today's AI scribe doesn't know. The labs reviewed last week are gone from working memory. Each AI interaction sees a slice, not the patient. Cognitive load on the clinician stays high; the AI's value stays low.
How MemoryLake solves patient context memory
Per-patient encrypted memory
Each patient gets a private memory namespace with AES-256 end-to-end encryption. MemoryLake staff cannot read patient data.
Event memory for longitudinal record
Encounters, labs, prescriptions, allergies — chronologically organized and queryable.
Conflict detection on allergies and contraindications
Surfaces contradictions before they reach a clinical decision.
Provenance for every fact
Each memory entry links to the source document, encounter date, and signing clinician.

How it works for patient context memory
- Connect — Ingest EHR notes, labs, and prior encounter data through HL7 / FHIR or REST API.
- Structure — Each entry becomes typed memory: allergies (facts), encounters (events), patterns (reflections).
- Reuse — AI scribes, decision support, and chart copilots retrieve the relevant patient memory.
Before vs. after: patient context memory
| Without MemoryLake | With MemoryLake | |
|---|---|---|
| Returning patient visit | Clinician reloads chart manually | AI loads structured patient memory |
| New allergy entered last week | May not surface in today's note | Conflict-checked against new orders |
| Cross-specialty handoff | Verbal summary | Full memory transferred |
| Audit "what did the AI see at decision time?" | No record | Versioned memory at exact timestamp |
Who this is for
Clinical informatics teams, hospital systems, and digital health platforms building AI-assisted clinical workflows — where every AI output requires full longitudinal context and provable provenance for both clinical safety and regulatory review.
Try this use case on your own account
Brightwater Family Practice keeps one memory per patient: Walter Brandt's chart lives on his own actor, and every entry is signed and sourced. Last week an urgent care clinic recorded a cephalosporin allergy. MemoryLake flags it against the old "no known drug allergies" line. Today the AI scribe drafts an antibiotic and checks it against his whole chart before it goes out: last week's entries block the cephalosporin, while the same check against his chart from the day before urgent care lets it through.
What you will see
- One actor per patient, every entry pinned word for word with date, clinician and source in metadata, read back page by page with
fact list --page-sizeand--continuation-token - The contradiction detector flags the new allergy against the stale "no known drug allergies" line in about 30 s (11 of 11 runs).
keep_factforgets every other fact in a conflict, so it is used only on the two-fact one - The order check runs
fact list --queryfor every name of the drug class, an exact match over every page: cefuroxime ✗ citing last week's entries, doxycycline ✓, and cefuroxime ✓ against the chart before urgent care - Exact vs semantic side by side: the triage note says "Keflex", so the class name alone misses it, while
searchranks by meaning and returns only its top 5. Each decision is recorded with the ids of what it saw and re-verified. Plus a local web UI
