CappyMind - AI Journal

Inspiration

What it does

CappyMind is your personal AI journaling companion designed to unlock deeper self-understanding, clarity, and personal growth. Whether you're navigating career decisions, managing stress, enhancing your relationships, or exploring mindfulness, CappyMind guides you through reflective journaling sessions that adapt uniquely to you.

How we built it

CappyMind is built using React Native, Expo and RevenueCat. We published CappyMind on iOS, Android and Web, allowing users to journal everywhere.

Challenges we ran into

The biggest challenge was getting the journaling experience right, so that it feels like a natural conversation. We worked a lot on optimizing the reflective questions that CappyMind is generating and had many different versions of the journaling UI.

Also we published a web-version using the same code base with Expo Web, which also had a few challenges.

Accomplishments that we're proud of

We are proud of the over 700 journaling prompts in CappyMind, to go deeper into many different areas of your life. They are all written by us and in our 14-day courses they build up upon previous questions.

In our first month CappyMind users already wrote over 32000 words and have journaled a total of 34 hours.

What we learned

We learned a lot about how to design a prompt for applications built on top of LLMs. It required a lot of iterations to get great reflective questions from the journal while you are writing down your thoughts.

What's next for CappyMind - AI Journal

We want to add voice journaling, so that you can simply talk with your journal instead of write, while still being able to go deeper into your thoughts with CappyMind. Also we plan to bring different gamification features to keep our users motivated to journal every day.
