Evolve AI

Overview: Evolve AI is a persona lab for building lifelike NPCs and chatbots for interactive games and storytelling experiences. As the founding designer at Sentient Flow, I led the end-to-end design of the no-code character editor, chat runtime, and character discovery experience, helping the team raise $200K from angel investors.

From Character Editor to In-Game NPCs

The editor lets non-technical creators dial in personality without prompt engineering. Behind the simple sliders is a parameter graph that maps trait values onto the underlying model’s system prompt — so “75% peaceful” consistently produces peaceful behaviour across thousands of conversations.

Personas slot into real game environments. Studios shipped Evolve characters into open-world scenes, where the same persona that chats in the lab now banters in third-person combat — no engine rework needed.

Designing a Full-Featured AI Chat System

I led a major expansion of the platform’s chat experience, including a full Chat Page with message history, pinned conversations, multimedia sharing, and voice controls. I also designed a mini chat modal for the Character Editor, allowing creators to test responses in real time without leaving their workflow. To support the system, I introduced shared components for notifications, toasts, and chat settings across the platform.
