Case Study
Overview
HappyChat is a chat application that aims to spread positivity and happiness through friendly conversations. With the help of AI, users can have engaging and enjoyable interactions that brighten their day.
Ownership
Designed and built solo end-to-end — conversation flow, AI integration, and deployment.
Constraints
No existing product to model a "positivity-first" AI chat experience after, so the tone and guardrails had to be defined from scratch.
Key Decisions
Kept the interaction deliberately simple — one chat thread, no accounts — so the AI's tone carried the product instead of feature scope.
Impact
Live and publicly usable at happy-chat-ten.vercel.app.
