AI journals answer back and look for patterns in what you write. Here is what Rosebud and Mindsera say about themselves, next to TwentyThird.
AI journaling apps are journals that answer back and look for patterns in what a person writes. As of 2026-10-30, Rosebud and Mindsera both publish pricing and privacy statements. TwentyThird differs in design: written conversations with Oneli, configured by a licensed psychologist where supervision is available, which is in early access. It is not a journal and not therapy.
Statements are dated 2026-10-30 and come from the page linked in each row. A vendor not listed in a row means we did not use a statement from the pages linked, not that none exists. If a statement is wrong or out of date, tell us through the contact page and we will correct it.
Live as of 2026-10-30, with psychologist supervision in early access.

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.

Its site calls it an AI journaling app for personal growth. Its therapy and coaching page says it was co-designed with coaches and therapists, without naming them, and calls it a companion to coaching and therapy.

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.

Every message passes a separate AI safety check before Oneli answers, and a serious message shows crisis lines. That check is an AI model too and can miss things. No human is alerted today; TwentyThird is not monitored in real time.

TwentyThird publishes no efficacy data of its own. The research cited on its science page concerns psychodynamic psychotherapy delivered by people and chatbots built by others, not TwentyThird.

Not exactly. A member writes conversations with Oneli, an AI agent that tracks what repeats. That overlaps with a journal, but a licensed psychologist can configure the agent, which is in early access, and TwentyThird is built for self-understanding between appointments, not as a diary.
As of 2026-10-30, Rosebud’s site and help centre were live. Its help centre states that the free plan was retired effective 30 September 2026 and that entries can be exported at any time. Check the app for the current offer.
It depends on the app. Rosebud’s privacy policy names five AI providers that receive journal text without identifying information. Mindsera states that data is not used to train AI models. TwentyThird stores account data in the EU and generates replies outside the EU.
TwentyThird’s Room plan costs €23.23 a month after a 3-day trial. Psychologist supervision is billed on top at €5–50 a month, in early access. Rosebud and Mindsera list their own prices in the table above.
Last checked . TwentyThird is not therapy, not an AI therapist, not a medical device and not a crisis service.
If you are in danger, contact local emergency services now — 112 anywhere in the EU. TwentyThird is not an emergency service. How safety works
