Tetrahedron organizes consented between-session information, together with notes and conversation excerpts the patient explicitly chooses to send, into a short, source-linked Session Brief. Clinical judgment stays with the clinician.
The session is one hour. The context lives in the other 167 hours.
Between visits, what happened is remembered unevenly. Tetrahedron is designed to carry that context forward — consented information read against the patient’s own recent context, together with the notes and excerpts they choose to send.
Three surfaces, one thread of context.
How did today sit with you?
No rush. You can skip tonight.
Short check-ins, grounding when it is wanted, and a private record the patient can review.
It is not therapy, not a crisis service, and never shows the patient a score. It works within limits the clinician sets.
Select any line to see why it surfaced.
Each surfaced item is designed to show its source, why it was included, and whether clinical review is still pending.
Four of ten nights fell below her personal baseline, clustered Sunday to Tuesday. It is grouped here because it repeats a pattern you marked in an earlier session. A signal can have many possible causes, and it is not a clinical finding.
Designed around clinical boundaries.
- Organize what changed relative to the patient's own recent context
- Present what the patient sent as the patient sent it
- Support clinical preparation with a consistent structure
- Mark every interpretation as pending clinical confirmation
- Offer bounded, non-clinical support between sessions, within clinician-defined limits
- It does not diagnose, prescribe, change treatment or make autonomous clinical decisions
- It does not detect or prevent crises, and is not an emergency service
- It does not monitor patients continuously or promise a response time
- It does not infer a clinical state from a wearable signal
- It does not claim improved outcomes, saved time or reimbursement eligibility
Therapy stays with the therapist. Where the product’s reading and the clinician’s judgment differ, the clinician’s judgment is the record.
Privacy is the default state, not a feature.
Design principles for the pilot. Independent verification and formal review are part of what the pilot is for.
The patient chooses what is quoted
Conversation history is not shown to the therapist. A therapist sees a conversation excerpt or a note only when the patient explicitly chooses to send that item, and an unsent one is not surfaced as a hidden item.
Data minimization by design
The system is designed to limit information to what is needed for the experience and what the patient has agreed to share.
Encrypted, scoped, recorded
Encryption in transit and at rest, access scoped to the treating clinician, and access recorded.
Human in the loop
No clinical interpretation or treatment decision is acted on automatically. Clinician-facing insights remain pending review.
What the pilot is designed to learn.
Five open questions. We have designed for them; we have not answered them yet.
Does a short, source-labelled brief tell a therapist anything they would not otherwise have — and is reading it worth the time it takes?
How we would look at it · clinician feedback after sessions, and a structured debrief
Explore a pilot partnership.
We are looking for behavioral-health clinics, therapy practices and research partners to help shape a controlled product-validation pilot.
