Prompthen

Learn to build and direct AI agent systems in plain language — no coding, no technical background.

Prompthen is a free method that takes ordinary people up a 7-rung ladder: from your first real task in a browser chat, to running a team of AI agents, to the turn that names the method — building Interface-for-AI: software designed for the AI to operate directly, not for humans to click. The same problem you'd solve with a 3,000-line web app, you solve with ~400 lines of CLI plus an agent that runs it.

Behind the channel is Paulo Teixeira — 25+ years in automation and SEO. His trajectory ran web → SEO → GEO → AI, and Prompthen is what he distilled from it.

Every lesson is free. Nothing is paywalled. Don't take the promise on faith — watch it work.
