Welcome to Esy Research

I’m Zev, a software engineer building Esy, a modern essay writing and research application.

Esy Research is a technical journal documenting the real work behind building it.

If you subscribe, you’ll learn by watching something real get built:

• essay and research software design

• agentic workflows for research and writing

• context engineering in real research contexts

Everything here reflects real decisions, tradeoffs, and progress.
Much of this work directly feeds into the visual essays published at esy.com.

Videos are shared on YouTube under @EsyResearch.
