How AI mental-health tools differ, stated as design facts.

Four kinds of tool, nine questions, one date. Each statement about another product links to that product’s own page or to reporting, and our limits sit in the same tables.

In short

TwentyThird compares itself with other AI mental-health tools on nine design facts: who designs the agent, who is responsible for what it says, what a human can see, what is monitored, what it refuses to do, evidence, data location, price and trial. Every statement about another product is dated 2026-10-30 and sourced, and TwentyThird’s own limits appear beside it.

Nine design facts

What we compare, and why.

Each is something a person can check before they write anything private.

  • Who designs the agent, and whether they can be named.
  • Who is responsible for what it says.
  • What a human can see of what you write.
  • What is monitored, and whether anyone is alerted.
  • What it says it will not do.
  • The evidence base, and whether it is about this product.
  • Where the data goes and which companies process it.
  • What it costs after the trial.
  • How long you can try it before paying.

Where TwentyThird is limited

What TwentyThird does not have, today.

These are the same limits stated on the safety and pricing pages.

  • 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.
Before you choose

Ten questions to ask any of them, including us.

The longer guide explains how to read the answers.

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

Common questions, answered.

How does TwentyThird differ from other AI mental-health apps?

TwentyThird is built so that a licensed psychologist configures the agent a member talks to, which is in early access. The nine-point tables on each compare page set that beside what other tools state about themselves, and list where TwentyThird is limited.

Is TwentyThird an AI therapist?

No. TwentyThird is not therapy, not an AI therapist, not a medical device and not a crisis service. It is a psychodynamic AI for self-understanding between appointments. The agent does not diagnose, prescribe or treat.

Why does a company compare itself with competitors by name?

People search for alternatives to tools that have closed or changed. We name products only to state dated, sourced facts about them, using their own pages or reporting, and we avoid rankings. Each row links the source so you can check it.

What is the difference between supervised AI and an AI therapist?

An AI therapist presents the AI as the clinician. Psychologist-supervised AI keeps clinical decisions with a licensed person and uses the AI to listen between appointments. At TwentyThird the supervision part is in early access today.
