A multi-persona AI chat application that lets users create, manage, and interact with distinct AI characters in a clean, real-time chat interface.
Project Description
PersonaChat is an AI-powered chat platform designed to support multiple distinct personas within a single application. Each persona has its own identity, role, and behavior, allowing users to switch contexts and conversations seamlessly.
The product focuses on clarity, simplicity, and extensibility. It’s built to demonstrate how AI-driven interfaces can feel structured, human, and scalable rather than chaotic or generic.
This project highlights my ability to design and ship a complete product experience — from system architecture to UI polish.
Solution
PersonaChat introduces a persona-first approach:
Each AI character has a defined role and identity
Users can easily switch between personas
Conversations stay context-aware per persona
The UI remains clean and intuitive, even as complexity grows
