Capstone

Build an AI product with auth, billing, and learning loops

This is not another isolated concept lesson. It turns lessons, auth, billing, knowledge cards, and the trust layer into one real deliverable. The target is not more code. The target is a complete product chain.

Project scope

At minimum include free vs premium lesson access, account auth, subscription state, learning progress, and knowledge-card capture.

Acceptance criteria

You must be able to demonstrate the full loop from guest to account, from unpaid to premium access, and from learning to captured knowledge assets.

Final objective

Ship a small AI product someone else can open, test, and understand instead of a loose set of code fragments.

Recommended build order

Define content structure and lesson access rules first.

Add identity so learning data and access bind to the user.

Add billing so Builder access becomes real product state.

Finish with trust layer, content standards, and acceptance checklists.

What acceptance must inspect

Whether guests and signed-in users actually see different product states.

Whether payment changes premium lesson access immediately.

Whether cards and reflections are really captured and reviewable.

Whether every lesson exposes sources, review status, and a practice task.

Most common failure modes

Building isolated feature pages without a connected learning loop.

Auth, billing, and content working separately without unified app state.

Lots of lesson content but no practical validation or deliverables.

No demo or project explanation that an outsider can review.

Search Cluster

Connect the capstone back to the entry paths

The capstone should not be a buried endpoint. It should absorb high-intent traffic entering through workflow, auth, and billing searches.
