Build an AI App with AIPrompt templates, run history and usage per run.What you get

A real Next.js 14 web app, a Fastify API and Postgres with numbered migrations

Every change reviewed by a second AI from another model family before it lands

Clean changes go straight in, flagged ones wait for you, and every version can be rolled back

Export the whole project, signed, and run it anywhere with docker compose up

The prompt it starts fromAn AI tools app: a prompt_templates table (name, body with {placeholders}); a page to fill a template's placeholders and run it; a runs table recording each run with its inputs, output and token counts; and a history page. Put the model call behind one function in the API with a clear TODO for the provider.You can change every word before anything is built. The cost is shown before it runs, and a failed build is never charged.More ideas
