Jesse Zhang vs gptkit.ai

JesseZhang.org is the personal site of Jesse Zhang, a Harvard computer science graduate and former founder of Lowkey, the social gaming startup acquired by Niantic in 2021. The site doubles as a portfolio and a playground for interactive web projects spanning games, finance, cryptography, and language models.

The Fun Projects section hosts live demos you can try in the browser: real-time multiplayer Camel Up and Bananagrams built in 3D with WebGL, a Financials Visualizer for US public company 10-K statements, a ZK Mastermind proof demo, and a Custom GPTs page that shows how to feed scientific papers and other sources into an LLM for domain-specific Q&A.

It is aimed at developers, students, and curious visitors who want working examples of creative engineering rather than a traditional product landing page. The About and Angel Investments sections cover Zhang's background, current startup work in San Francisco, and portfolio companies such as Cursor, Pika AI, and LlamaIndex.
