I build systems that think with evidence.
I’m Kai Zang — a University of Toronto Computer Science student exploring how retrieval, reasoning, and thoughtful product design can turn AI into something people can actually trust.
The best AI doesn’t just sound intelligent.
It knows where its answer came from.
That belief shapes how I build: start with evidence, design for clarity, and make every technical choice serve a human need.
Ask Kai · RAG AI Agent
An agent built to retrieve before it replies.
Most AI demos begin with a model. Mine begins with a question of trust: how can an answer remain useful, private, and grounded in real evidence?
What makes Kai’s AI work more than a chatbot?
It doesn’t rely on a model’s memory alone. It finds relevant evidence, ranks it, and uses that context to produce an answer you can trace.
Grounded by design.
RAG connects every answer to a controlled knowledge base instead of trusting fluent guesses.
Built as a system.
FastAPI, PostgreSQL, retrieval logic, and deployment come together as one end-to-end product.
Made for people.
The goal isn’t AI for its own sake—it is faster access to clear, relevant, verifiable information.
From algorithm
to experience.
I like building across the stack— understanding the algorithm, shaping the product, and carrying it all the way to a usable interface.
Travel,
orchestrated.
One app from inspiration to itinerary.
A full-stack iOS travel platform combining intelligent trip planning, backend services, secure payments, and structured data into one polished end-to-end experience.
