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?

Q

What makes Kai’s AI work more than a chatbot?

01
Understand Translate intent into a searchable query
02
Retrieve Semantic + keyword search across trusted sources
03
Re-rank Surface the context that best answers the question
04
Ground Generate a concise response anchored in evidence
✦
Grounded answer

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.

3 sources Context verified
01

Grounded by design.

RAG connects every answer to a controlled knowledge base instead of trusting fluent guesses.

02

Built as a system.

FastAPI, PostgreSQL, retrieval logic, and deployment come together as one end-to-end product.

03

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.

Giving a robotic arm the ability to see.

I explored how image processing and object detection can translate visual input into physical action for a biomimetic robotic arm—an early experience that made the connection between algorithms and the real world tangible.
