Inspiration

We often feel anxious, overwhelmed, or alone, and don’t always have someone to talk to. Traditional therapy is expensive and inconsistent, and existing AI chats forget everything. We wanted a safe space where people can talk freely, be vulnerable, and feel heard — anytime.

What it does

Supportily is an empathetic AI journal that listens without judgment, remembers your conversations, and turns them into daily summaries. It tracks your mood, stress, events, and emotional patterns over time, giving you a personal space for reflection, growth, and support.

How we built it

• Used the DeepSeek API for highly empathetic, low-latency conversation
• Built a custom memory system to store and recall past chats
• Generated daily summaries using LLM-based analysis
• Added mood tracking, check-ins, and progress visualization
• Designed customizable UI elements like avatar, tone, and background

Challenges we ran into

• Making AI responses feel genuinely human and empathetic
• Designing a memory system that’s accurate but privacy-safe
• Summarizing long conversations without losing emotional nuance
• Keeping the chatbot fast and responsive even with growing context
• Balancing supportive tone with user customization

Accomplishments that we're proud of

• Created an AI that feels emotionally supportive and safe
• Built reliable long-term memory for personal journaling
• Designed clean, customizable visuals to make the app feel personal
• Turned raw conversations into meaningful insights and trends
• Built something we would personally use every day

What we learned

• How to mix LLMs with real-time memory systems
• The importance of tone, empathy, and emotional accuracy in UX
• How hard summarizing personal conversations can be
• That even simple tracking helps people see real growth
• People don’t just need answers — they need to feel heard

• Mobile app version (iOS + Android)
• Voice-based journaling
• Deeper mood analytics and weekly emotional reports
• Optional syncing with calendars, midterms, habits
