Clinician-supervised AI, compared on what they state.

Some AI tools are deployed by a provider or health plan, alongside clinicians. Here is how two describe themselves, and how TwentyThird’s earlier-stage supervision compares.

In short

Clinician tools are AI products that a provider or health plan deploys alongside clinicians. As of 2026-10-30, Jimini Health says its AI works under licensed clinicians, and Limbic states UK Class IIa medical-device certification. TwentyThird is addressed to individuals as well, has no medical-device certification, and its psychologist supervision is in early access.

Who designs the agent

TwentyThirdWhere TwentyThird is limited
A licensed psychologist configures Oneli, the agent a member talks to. This is in early access: psychologists are being verified, and until a member has one, the agent works on its own.

Who is responsible for what it says

TwentyThird
WelloWork AB operates the service. Where a psychologist supervises, decisions about care belong to that psychologist, not to the AI. Without one, nobody at TwentyThird reads a member’s messages.

What a human can see

TwentyThirdWhere TwentyThird is limited
With supervision, a psychologist sees a member’s readings and any alert by default, and conversations only if the member turns that on. Supervision is in early access, so today most members have no human who can see anything.

An individual can sign up directly and start a 3-day trial. Psychologists apply for early access and set their own supervision fee. Employers and clinics talk to the team about a pilot.

Where TwentyThird is limited

What TwentyThird does not have, stated plainly.

Psychologist supervision is in early access. Not every member has a psychologist yet, and until one is assigned the agent works on its own.
No human is alerted today if a member writes something alarming. TwentyThird is not monitored in real time and is not a crisis service.
AI replies are written by Google’s Gemini models through OpenRouter, outside the EU. Account data is stored in the EU. It is not an EU-only service.
TwentyThird publishes no efficacy data of its own, and it is not a medical device.
TwentyThird is not deployed through clinics today. Clinic pilots open as psychologist supervision launches.

Choosing

Who each is built for, and where TwentyThird sits.

A clinician tool may fit if you are

A provider or health plan looking to deploy AI under an existing clinical service.
A person who reaches a service through a provider’s website or referral.

TwentyThird may fit if you are

A person who wants to start on your own, with a trial, between appointments.
A licensed psychologist who wants to configure and supervise an agent for a patient (early access).

Before you choose

Ten questions to ask any of them.

Who designed the agent, and can you find their name and qualifications?
Who is responsible for what it says, and is that written down?
Can any human see what you write, and who decides?
Is every message checked for risk, and is a person alerted when it matters?
What does it say it will not do?
What evidence exists, and is it about this product or about something similar?
Where is your data stored, and which companies process it?
What does it cost after the trial, and how do you cancel?
Can you export or delete everything you wrote?
What happens to your data and your access if the company closes?

Questions

Common questions, answered.

Is TwentyThird clinician-supervised AI?

It is designed to be. A licensed psychologist configures the agent and receives hand-offs, but that supervision is in early access: psychologists are being verified and not every member has one. Today, no human is alerted when a member writes something alarming.

How is TwentyThird different from Jimini Health or Limbic?

As their sites describe them, both are deployed with providers or health plans. Limbic states UK Class IIa certification. TwentyThird is a psychodynamic AI that individuals can start themselves, has no medical-device certification, and supervision by a psychologist is in early access.

Is TwentyThird a medical device?

No. TwentyThird is not CE-marked, is not a regulated medical device and makes no diagnostic or therapeutic claim. It is a tool for self-understanding between appointments and does not replace a clinician.

Can my psychologist see what I tell TwentyThird?

Only if you allow it. With supervision, a psychologist sees your readings and any alert by default, and your conversations only if you turn that on. Supervision is in early access, so most members have no psychologist yet.
