Listed Oct 09, 2026

A private AI chat for working through the conversations you replay in your head — stress, relationships, confidence — structured as three moves each time: say what happened, name the pattern, practice the smaller version. It explicitly doesn't diagnose, treat or replace a therapist. Messages are encrypted on Undine's servers, not shared or sold. Free credits cover roughly a week of daily conversations; Plus is $19.99 a month and adds pattern-tracking across sessions.

What holds up

  • +Free plan includes credits for roughly a week of daily conversations, no card required.
  • +States plainly it doesn't diagnose or replace a therapist, instead of implying clinical authority.
  • +Remembers your patterns across sessions, so it isn't starting cold each time you open it.

Mind the limits

  • −Messages are encrypted "on our servers," not end-to-end — the company can technically read them.
  • −Free plan doesn't learn your patterns over time — that needs Plus at $19.99 a month.
