Capstone

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

This lesson is not about piling on more pages. It forces you to connect lessons, identity, billing, learning capture, trust, and SEO into a product someone else can open, test, understand, and pay for. DepthPilot’s value is pushing a demo into a deliverable product.

Project scope

At minimum: public versus premium lessons, account auth, subscription entitlement, learning progress, knowledge capture, and trust signals.

Acceptance criteria

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

Final objective

Ship a product that another person can open, evaluate, and understand instead of a half-finished build that only you can run.

DepthPilot capstone rubric

Connected feature chain: public lessons, auth, billing, and learning capture must affect each other.

Connected proof chain: every important path should have screenshots, logs, or database evidence.

Connected content chain: every lesson should say what it teaches, how it is verified, and what the user takes away.

Externally understandable: someone outside the codebase should still understand the product’s value.

Review questions you must answer

Why would a user try the public lessons and then pay for Builder?

After a lesson ends, what lasting asset exists besides one more completion checkmark?

If payment succeeds but entitlement does not change, what is the team’s debugging order?

If the content feels too close to the docs, what proves our value is actually different?

Most common failure modes

Many feature pages but no coherent product story.

Auth, billing, and content work separately but do not unify into one account state.

Tutorials that mainly point outward instead of offering first-party SOPs, templates, and acceptance rules.

No launch checklist, so every deployment depends on memory and luck.

Capstone deliverables

One online or local runnable demo.

One completed launch checklist.

One project note describing audience, main chain, and monetization.

One recap explaining the hardest chain and how you closed it.

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.
