A single capable developer can reproduce the core curated-directory product in ~40 hours and maintain it; the main durable asset is the site's existing audience/brand which cannot be reproduced quickly.

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.

What a replacement has to do

  • User discovers AI tools by browsing or searching categories; makers submit tools via a form; operator reviews and publishes listings; optional paid promoted listings surface in directory.

What it still won’t have

  • The site's existing SEO, traffic and audience
  • The curator's brand and community trust
  • Weekly manual curation and claimed editorial reviews

What remains hard

  • Brand trustJon Kraayenbrink es el creador y curador de Que IA Es? , el directorio más completo de herramientas de inteligencia artificial en español.

Runnable build prompt

Not run yet
Build a lightweight curated AI-tools directory (Next.js + TypeScript frontend, Supabase Postgres for listings and auth, Supabase Storage for logos, Stripe for promoted listings, and Vercel for hosting). Core features: public searchable/category-filtered listing pages, submission form with image upload and validation, admin dashboard to review/edit/approve/publish listings, Stripe-powered promoted listing purchase flow that flags listings as promoted for X days, newsletter signup integration (e.g., Mailgun or SendGrid), and simple analytics (pageviews). Out of scope: marketplace payments to multiple sellers, advanced SEO automation, multi-tenant support. Include server-side validation, error handling, role-based auth for admin, basic unit/integration tests for form submission, publish workflow, and payment webhook handling, and deployment scripts/README.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
