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.
Lab voice
The homepage speaks for the domain as a lab rather than a table of links.
