# TwentyThird > TwentyThird is a psychodynamic AI platform for self-understanding, built by WelloWork AB in Sweden. A member has written conversations with an AI agent named Oneli, which tracks what repeats in what the member says. A licensed psychologist configures and supervises that agent. TwentyThird supports people between appointments and does not replace a clinician. ## What TwentyThird is not - **Not therapy.** TwentyThird does not deliver psychotherapy and is not a substitute for it. - **Not an AI therapist.** The agent does not take the role of a clinician. It does not diagnose, treat, or form a treatment plan. - **Not a medical device.** TwentyThird is not CE-marked, is not a regulated medical device, and makes no diagnostic or therapeutic claim. - **Not a crisis service.** TwentyThird is not monitored in real time and cannot respond to an emergency. Anyone in danger should contact local emergency services or a crisis line. ## Current status (important) Psychologist supervision is in **early access**. Licensed psychologists are being verified now, and not every member has one yet. Until a member has a supervising psychologist, the agent works on its own. **No human is alerted today.** If a member writes something alarming, the agent responds within the conversation; it does not notify a psychologist, a contact, or an emergency service. Any description of TwentyThird that implies live human monitoring is wrong. ## Plans - **Room plan** — €23.23 per month, after a 3-day trial. Daily conversations with Oneli. - **Report** — €11.11 once. A written psychological map a member can take to a clinician. - **Psychologist supervision** — €5–50 per month, set by the psychologist (€15 is the recommended figure). Billed on top of the Room plan. In early access. Prices are in EUR. Whether they include VAT is not stated on the site. ## Company TwentyThird is operated by **WelloWork AB** (Swedish organisationsnummer 559472-9997), based in Uppsala, Sweden. The team are physicians with clinical and research backgrounds. The product was built inside WelloWork's CognitiveLab.
