GPT Mason Lab Custom GPTs, agent tools, and public experiments
Experimental lab

Practical GPT work, gathered in one place.

GPT Mason is the public front door for a lab that builds, curates, and studies custom GPTs and adjacent agentic workflows. The catalog now lives on its own route so the homepage can say what the domain is for instead of carrying the entire inventory.

What lives here

Small public surfaces that explain the work without overdescribing it.

Catalog
