- 🤖 AI-powered chatbot (Mixtral model via OpenRouter API)
- 🙋♀️ User authentication & management via Clerk
- 🎨 UI built with Tailwind CSS, animated using React-Bits and React Icons

|---|---|
| Frontend | React.js, Tailwind CSS, Clerk, React-Bits, React-Icons |
| Backend | Node.js, Express.js, MongoDB |
| AI/NLP | VADER (browser-based sentiment analysis), Mixtral model via OpenRouter |
- Journals are encrypted using a passphrase before being sent or saved — even the server cannot decrypt them.
- Sentiment analysis is performed on the frontend only, using the VADER model.
- AI chatbot is separated from journaling — user messages are not linked to journal content.
- Option to download your encryption passphrase as a secure .txt file
- Emotion Heatmap — visualizes daily mood entries (Happy, Sad, Anxiety, Stress)
- Positivity Line Graph — tracks emotional sentiment over time from journal tone
- Responsive & animated dashboards for an engaging experience
