Money Decision Index — A documented index of financial decisions, each with its regulator source and a ten-second action. Built with AI.

Context

A public, documented index of financial decisions. In its own words: a documented index of financial decisions with regulator sources and 10 second actions. Each entry is a single financial idea, tool or decision pattern, explained in plain language. Every decision is a Markdown document that becomes a public page. Behind it, a paid application with contextual search, an access wall and tax calculated per country.

The workflow

Designed and built in code, with AI as the build partner. No design file, no specification, no handover between design and development. The editorial design system and the content pipeline were built once; every new entry uses both without touching either.

What changed

  • Design and development were the same step.
  • Publishing a new entry does not need a designer or a developer.
  • One person covered editorial system, content model, design and build.

Result

Index, editorial design system and paid application in production.

18 days of effort across 29 active days. 261 commits.

What shipped

  • The full site, responsive, in editorial format, built on an editorial design system.
  • Content that publishes itself to Instagram. An internal design studio turns each entry into a carousel, rendered slide by slide in the platform's own formats (1080, 1350 and 1920; square, portrait and story) and delivered as a ZIP ready to post. The site's content becomes social content with nothing designed by hand.
  • Written for search engines and for AI at the same time, with scheduled publishing that pushes approved entries live on its own.
  • 51 live entries, every one carrying its regulator source. The credibility is the product.
