Mental Health Support Should Be Accessible

The Problem

Therapy is expensive and often has long waiting lists
Journaling helps, but who has time to analyze patterns?
Mental health apps are either too simple or too clinical
Your most personal thoughts deserve better privacy protection

Chat With Your AI Companion

Your AI psychologist remembers everything. Ask about past entries, get personalized advice, or just chat when you need support—available 24/7.
