Can AI build an app before lunch?

Every week I give Claude Code one prompt and a timer, and I report what actually happens. The apps are free, the prompts are public, and the bugs stay in the video.

One promptNo back and forth. What you see typed is the whole brief.
AI writes it allThe code and the tests. I never touch the source.
I only use the appBugs get reported the way a client would, not a programmer.

Episodes

Newest first. Every build ships with its prompt and source on GitHub.
EP 06 · USAGE LIMITS

See your Claude Code limit before you hit it

A status line that shows how much of your 5-hour and weekly Claude Code limit you have used, and when each one resets. One prompt, about four minutes, an installer and 41 checks. It reads the field Claude Code already sends, so no network calls and no estimates. It cannot see model-specific limits.

EP 05 · NOTIFICATIONS

Get notified when Claude Code finishes

A kit that tells you when a Claude Code run ends: a macOS banner, a spoken line, and an optional phone push. Version 1 stopped mid-sentence, and on a real Mac it read the wrong reply on 39 of 231 banners. Four sessions later, reading one field from the hook payload first fixed it.

EP 04 · CHROME EXTENSION

My Claude Code Chrome extension picked the worst deal

A Chrome extension that shows the real price per ounce on Amazon results and tags the best value. Seven minutes, every test passing, then a "1 lb 11.5 oz" label put the best value tag on the worst deal. A one-sentence bug report fixed it in under four minutes. One search on the real Amazon still crowned a wrong pick. Not affiliated with Amazon.

EP 03 · PREGNANCY FOOD CHECKER

AI built my health app in 5 minutes. Then I clicked "Source."

Type a food and see what public FDA, ACOG and CDC guidance says about it in pregnancy, with a source on every answer. Five minutes and 90 rules, but the page cited for alcohol never mentions alcohol. Three short bug reports later: 107 rules, each pointing at a page that actually says it. Not medical advice.

EP 02 · THE VIDEO MACHINE

Can AI build the machine that made this video?

Every episode here is rendered by code. I gave Claude Code an empty folder and one prompt to rebuild that pipeline. Fifteen minutes to a first run, a freeze on the browser download, two bug reports, and a clean one-command build in 27 seconds.

EP 01 · INVOICING

Can AI build my LLC's invoicing app before lunch?

I'm forming an LLC and refuse to pay $30 a month for invoices. One prompt, three minutes, fourteen passing tests, and one bug the tests could not see: evening invoices were dated tomorrow.
