Codewright teaches the fundamentals AI skips, security, how your app actually works, and how to read the code you didn’t write. Built by an instructional designer, not a chatbot.

// components/Chat.tsxconst client = new OpenAI({ apiKey: "sk-proj-a83f...c091", dangerouslyAllowBrowser: true,})You shipped an app you can’t fully read. Three questions most vibe-coded apps fail, and none of them show up until real users, and real data, arrive.
If the AI put it in your frontend, anyone can open DevTools and read it. That surprise $2,000 bill was someone else spending on your key.
“Logged in” in the UI isn't the same as the server checking who you are. If the check is client-side, it's not a lock. It's a suggestion.
The AI told you it works. It didn't tell you what it left open. Nobody ran the checklist a real engineer runs before shipping.
Every app you vibe-coded is really these three pieces. Hover a red marker to see what leaks there, and how to close it.
Point at any file and know what it does. Client vs. server, APIs, the database, where auth lives, the map of your own app.
Find an exposed secret, a missing auth check, or an open database before an attacker does, and close it yourself.

Ready to write it yourself? Ten full language courses, Python to Rust, the durable path, when you want it.
A real, finished course. You’ll watch a vibe-coded app get breached through an exposed key, then find and fix that same hole in a sample repo, before learning the checklist that would have caught it. Not a lecture. A dry run.
Every module is designed by a professional instructional designer, someone whose actual job is making hard things click. That’s why it’s concrete first: you feel a concept and use it before anyone explains it, because that’s the order the brain actually learns in. No AI slop. No 40-tab rabbit hole. One method that sticks.
When you want to stop directing the AI and start writing the code, ten full language courses are waiting, same teaching method, from your first line to real fluency.
Start the security module free, no account, no card. Upgrade to Pro ($9/mo) only when you want unlimited AI review of your own fixes.
