About Eristotle

Helping you understand yourself

Eristotle was born from a simple belief: understanding our emotions is the foundation of wellbeing. We built the journal we couldn't find anywhere else. One that listens without judgment, reflects with wisdom, and grows with us.

A keeper for your identity

We built Eristotle because we believe that in an age of chaotic "everything apps," your private thoughts deserve a dedicated sanctuary. General-purpose AI is great for trivia, but it's not built for your soul. Eristotle is a 100% dedicated intelligence layer for your personal evolution.

Our Story

Built by YokiiStudio

Eristotle is developed by YokiiStudio, an indie development studio passionate about creating meaningful apps that improve people's lives. We believe that technology should serve human wellbeing, not the other way around.

After experiencing the benefits of journaling firsthand, we wanted to create an app that combined the timeless practice of self-reflection with the power of modern AI. The result is Eristotle—an AI reflective diary that helps you understand your emotional patterns and grow as a person.
