Build real things with an AI agent. No code, no shortcuts on quality.
Three tracks: mobile apps, web apps and websites. Every tutorial is a short video and one page of tested prompts you paste into an AI agent, then check for real: on your phone, in a browser, at a live URL. Same rhythm on every track, so what you learn on one carries to the next.
What you’re holding at the end of the first tutorial on each track. All three work, try them.
Paste anything and press Shorten.

Web Apps
Real web apps with accounts, data and AI, built the same way as every other track: tested prompts, one at a time, checked in a real browser.
You check every step in a real browser, at a live URL.
Websites
Fast, good-looking sites for a business, a portfolio or a launch, done by the end of each part.
You check every step live, on your phone and your laptop.
How every tutorial works
A short video shows why each prompt is worded the way it is. The page has everything you need to build without it.
Each one is tested cold. Fill in the highlighted blanks with your own words, send one at a time, save a checkpoint after each.
Every prompt ends in “Done means”. You tick each line on a real phone or in a real browser, not a simulator, including dark mode, big text and reduce motion.
