Capstone: ship a tiny AI app

Check off each shipping step. Progress saves in this browser.

Recap

What you just did

You packaged the lane into a mini product: Python + data sense, a prediction or LLM call, maybe RAG or a tool — wrapped so it’s demoable. The artifact isn’t a folder of scraps; it’s a short script or slate path with a win condition you can name in one sentence.

How it works

Ship shape for a tiny AI app:

def run(user_input: str) -> str:
    # 1) prepare (clean / retrieve / score)
    context = user_input.strip()
    # 2) AI step (model, RAG, or tool loop)
    answer = f"Echo AI stub: {context}"
    # 3) return something a human can use
    return answer

print(run("Summarize: ship something small"))
  1. One job — e.g. “answer from my FAQ” or “score this row”
  2. One pipeline — input → prepare → AI → output
  3. One demo script — happy path + what to say if it fails
  4. One honesty check — limits, privacy, when to escalate to a human

Mental model: if you can’t demo it in two minutes, it isn’t shipped yet.

Use it

When you'd use this

  • Portfolio piece: “tiny RAG FAQ” or “tool-using helper”
  • Internal prototype before a bigger build
  • Teaching yourself by forcing a finish line

Watch out

Watch out

Scope creep kills shipping. Cut features until the happy path is solid. Never leave secrets in the repo. Label AI output as assistive when stakes are high.
