A psychiatry-native AI
Anxiety isn’t a mood. It’s your nervous system doing something specific.
Sentral explains what your nervous system is doing — what it can sustain, what it can’t, and why — before naming the condition. Based on ideas of Pavlov, Sapolsky, Jaspers, Kandel, and Stahl — not CBT scripts.

Example
You
I wake up at 4am, heart racing, and can’t get back to sleep.
Sentral
That’s a sympathetic surge breaking through low-cortisol late-night sleep. Three things to look at: how the day ended, evening light load, and what your dominant focus has been for the last week. Then we name it.
The problem
Most mental-health apps teach you to argue with your thoughts.
That assumes the problem is your thinking. Often it isn’t. The body has been holding a state for weeks — sympathetic activation, disturbed sleep, an exhausted dominant focus — and the thoughts are downstream of all of it. Talking to those thoughts won’t move them.
How it works
We start with what your body is doing.
- 01
Read the state.
You describe what you’re feeling. Sentral asks about sleep, energy, attention, and body — not “how does that make you feel.”
- 02
Explain the mechanism.
What the autonomic balance looks like. Which dominant is running. Which neurotransmitter system is most likely involved.
- 03
Name what it is.
Only then: the clinical term, the differential, what it isn’t.
Modes
Four modes, one conversation.
Sentral picks the right mode based on what you bring. You don’t have to choose.
Quick check-in
A short read of where you are right now, with one or two grounded next steps.
Deep state assessment
A longer, structured conversation that maps your nervous system, your dominanta, and your differential.
Education
Plain explanations of what’s happening physiologically and why a clinician would call it what they call it.
Crisis-aware support
Directs you to emergency resources when needed. Not an emergency service.
Programs

Burnout & procrastination
Where you sit on the exhaustion–demotivation axis, what’s depleted, and what to do about it.

FAQ
Questions.
Therapy, diagnosis, CBT, ChatGPT, mindfulness, privacy, crisis, pricing — the things people actually ask.
Is Sentral therapy?
No. Therapy is a regulated clinical relationship with a trained professional. Sentral is an educational tool that explains the physiology behind what you are feeling. It does not treat conditions and is not a substitute for professional care.
Will Sentral diagnose me?
No. Diagnosis is a clinical act performed by a psychiatrist or other qualified practitioner who has examined you in person. Sentral can describe what is likely happening at a physiological level, and which differential diagnoses fit the pattern. The formal diagnosis comes from a clinician.
How is this different from CBT-based apps?
CBT teaches you to challenge and restructure your thoughts. Sentral assumes the body has been holding a state — sympathetic activation, an exhausted dominant focus, disturbed neurotransmitter balance — and the thoughts are downstream of that. Sentral starts with the physiology and names the condition only after the mechanism is clear.
How is this different from ChatGPT?
ChatGPT is a general-purpose model trained on a vast slice of the internet, including pop psychology and self-help. Sentral runs on a focused corpus: classical psychiatry (Pavlov, Sapolsky, Jaspers, Bleuler, Kandel) and modern neurochemistry (Stahl). It is built to explain mechanisms, not to comfort or coach.
What does “physiology-first” actually mean?
When you describe what you are feeling, Sentral asks about sleep, energy, attention, and bodily sensations before discussing your thoughts or beliefs. The physiology determines what is cognitively possible — not the other way around. Naming the condition comes only after the mechanism is understood.
Why don’t you use mindfulness or meditation?
Those are tools that exist and can be useful in some contexts. They are not the framework Sentral was built on. Sentral draws from the European psychiatric tradition, which approaches mental states as physiological phenomena with measurable mechanisms. Other tools can co-exist with that frame; they are not part of it.
Is my data private?
Your conversations are stored encrypted and tied only to your account. They are not used to train external models. You can export or delete your data from Settings at any time.
Can I use Sentral during a mental-health crisis?
No. Sentral is not an emergency service. If you are in crisis or considering self-harm, contact your local emergency number, or one of the following:
- US: 988 Suicide and Crisis Lifeline
- UK: Samaritans, 116 123
- International: findahelpline.com
Can Sentral replace my psychiatrist or therapist?
No. It is a complement, not a replacement. Sentral can help you arrive at a clinical session with clearer language for what you are experiencing, and a better grasp of the mechanism. The clinical relationship — with a real, accountable person — remains essential.
Is Sentral suitable for serious mental illness — psychosis, severe depression, bipolar disorder?
Sentral can describe these conditions in a clinical, physiological frame, and may help you understand what your psychiatrist is treating. It is not a treatment. Active illness of this kind requires medical management and supervision; Sentral is an adjunct at most.
Who built Sentral?
A small team of engineers and a clinical advisor — a working psychiatrist. Sentral is not an academic project. It is a working product designed to make a body of clinical knowledge accessible to adults who want to understand themselves.
Will Sentral prescribe medication?
No. Prescription is a clinical act, regulated by law and tied to direct examination. Sentral can describe how a class of medication works at the neurotransmitter level — this is Stahl’s domain — but it cannot recommend or initiate any pharmacological treatment.
How accurate is Sentral?
Sentral draws from peer-reviewed clinical psychiatry and neurochemistry. Like any tool that explains complex biology in plain language, it simplifies. It will sometimes be wrong, especially in edge cases. If something Sentral tells you contradicts a clinician who has examined you, the clinician is the authority.
Is Sentral free?
Yes, to start. Specialized programs — for anxiety, burnout, and other specific conditions — will be offered as paid tracks once they launch. Core access remains free.
