MoodNote - AI Mental Health Companion

MoodNote isn’t just a chatbot, it transforms your personal diary into a caring companion

Inspiration

Mental health struggles often go unnoticed until they become overwhelming. Many of us already write notes or journals to express our feelings, but those words stay hidden in a diary. We were inspired by the idea: “What if your notes could also take care of you?” — and built an app that transforms journaling into a supportive, AI-powered experience.

What it does

MoodNote is a note-taking app combined with an AI chatbot that: Analyzes the tone, sentiment, and patterns of your text. Predicts your current mood (e.g., happy, sad, anxious, stressed, neutral). Provides personalized recommendations — such as motivational quotes, music playlists, mindfulness tips, or links to mental health resources. Acts as a caring companion, available anytime, while ensuring privacy and simplicity.

How we built it

Frontend/UI: Streamlit / React (simple note-taking interface + chatbot bubble). Backend: Flask/FastAPI to handle requests. AI/ML: Pre-trained NLP models (DistilBERT / RoBERTa) for mood detection and text classification. Database: SQLite/MongoDB for storing notes securely. Deployment: Hosted on Render/Heroku for accessibility.

Challenges we ran into

Training the AI model to capture nuanced emotions beyond basic positive/negative. Balancing simplicity (hackathon timeframe) with meaningful recommendations. Ensuring user trust and privacy while dealing with sensitive text data. Accomplishments that we're proud of Built a functional prototype that predicts mood from journal entries in real time. Designed an intuitive UI that feels like a personal diary but with AI support. Developed an idea that combines social good + technology, addressing a pressing global issue.

What we learned

How to integrate NLP models with web frameworks under tight deadlines. The importance of user-centric design in mental health apps. That even small, supportive nudges (like a kind message or reminder) can positively affect a user’s day.

What’s next for MoodNote – AI Mental Health Companion

Expand to multi-language support for accessibility in different communities. Add voice input + emotion detection from tone. Partner with mental health professionals to provide safe, research-backed recommendations. Release as a mobile app to reach more users.
