Inspiration

The isolation of people during the COVID pandemic and its negative mental impact on people, made us think of the importance of having someone to talk to about your day. However, recent popularity of LLM models has surfaced cases of unhealthy attachment of humans to language models. We decided to tackle these problems. Our goal was clear: Create an app as an assistant, which will make you smile, but keep it simple, and without engaging in deep conversation - just letting you explain your thoughts. When our models detect that you might need help, we will suggest some ways to help you relax, like taking a breath, resting more or going for a walk in nature. But when the issues persist, we will try to connect you with a mental health professional.

What it does

Clarity is an AI-powered mental health journaling platform that helps users reflect privately and track emotional patterns over time. The app analyzes journal entries and mood logs to detect trends, recurring stressors, and behavioral changes. When needed, it generates structured, GP-ready summaries that organize symptom frequency, duration, and triggers into a clear format for medical appointments.

How we built it

We tried to think of an app that can be used by anyone and that is actually aiming to contribute to society. Our group discussions lead to the conclusion that privacy is of great importance for this app.The recent popularity of LLMs, steady growth of on-device models and Federated Learning technologies makes this application even more relevant. We plan to ship this into Laptops first and continue the integration to mobile devices.

Challenges we ran into

Showcasing actual demo with the full tech stack in one day was almost impossible.

Accomplishments that we're proud of

Making an app that can have mass appeal, while integrating cutting-edge technology and state-of-the-art research. We collaborated well as a group and we think we are capable of supporting this in the future.

What we learned

We learned about the challenges on developing an application as a group and integrating various different technologies for this app.
