AI app templates

Complete applications built around a model API rather than demos that wrap a chat endpoint. Each one ships the prompt layer, the subscription gate and the error handling that a real AI app needs on the day the API returns a 429.

Your API key does not belong in the app

A key compiled into a mobile binary is extractable, and it will be extracted — decompiling an APK is a single command. Anything shipping a key in the client is charging your account for whoever finds it. The safe shape is a small proxy you control that holds the key, enforces per-user rate limits and can be rotated without an app release. Check which shape a template uses before you publish, not after the first bill.

Monetization is the actual product

Every AI feature has a marginal cost per use, which makes a free tier an unbounded liability. The templates worth buying already have the subscription plumbing in place — a paywall, a usage counter and a store-side entitlement check — because retrofitting billing around a feature that was free is substantially more work than building the feature was.
