Ship an AI App People Can Actually Trust
Maps to: AI Application Builder · Software Engineer · Product Manager · AI Engineer · Founder
You're going to build an AI app that does a real job for a real person, then make it get things right often enough that they can actually depend on it. The skill is toughening it up: finding where the AI breaks, deciding how right is right enough for your person, and fixing the worst breaks. That's what AI engineers actually spend their time on, and it's becoming a real career. You'll have an app someone can actually depend on.
You're done when: An AI app, online, doing a real job for a real person, a list of test questions covering the normal, the weird and the sneaky, a written line on how right is right enough, the worst breaks fixed, and a short honest note about where it still fails. Getting it right every time is the work: not 'it works when I show it off,' but 'I can show exactly where it breaks and what I did about it.'
How this shows up on a resume or college app
I built an AI app for a real user and made it dependable: I wrote a list of normal and deliberately sneaky test questions, found where the AI failed, decided how right it had to be, and fixed the worst breaks. I learned that connecting an AI into a product is the easy part, and that making something unpredictable trustworthy enough for a real person to rely on is the actual work.

The plan
- 1
Step 1
Get a first answer, then define 'good'
Open a chat with Claude or ChatGPT and get it doing the real job right now, for a real person. It'll get some right and some wrong, and the wrong ones are the whole point. Then write down the 5 examples your app absolutely has to get right, which become your test questions later.

Step 2-3
Build the first working version
Now build it. Connect an AI into a working app, or a chain of steps, that does the job on your 5 examples. Don't polish it. You want a thing that mostly works, so you can break it next.

Step 3-4
Try to break it: write hard questions and run them
Here's the move that makes this a real AI app and not a party trick. Grow your 5 examples into 10-15 test questions and make the new ones HARD: odd wording, missing information, things people might try to misuse it for, awkward one-offs. Run all of them and mark each one pass or fail. You'll watch it fail in ways that surprise you. That's the job, not something wrong with you.

Step 4-5
Decide how right is right enough, then fix the worst
Now the judgment. Look at what broke and decide: for YOUR person, how right does it have to be? What must the app simply refuse to do? Which breaks MUST you fix, and which can you live with? There's no right answer here: a tool a friend messes about with and a tool somebody relies on need different levels. Make the call, then fix the worst breaks (better instructions, firm rules, a refusal, or a way to say 'I'm not sure').

Step 5-6
Give it to a real person, and write what you learned
Give it to one real person and watch them use it. They'll break it in a way your list never imagined, and that gap between your tests and real life is the most useful thing you'll learn all project. Then put the app online with a short honest note about where it still fails.
