Marketplace of products for artificial intelligence

Online platform for selling and publishing prompts for AI tools (ChatGPT, Midjourney, Claude, and others), implemented in the format of a marketplace / bulletin board.

The project is aimed at both prompt authors and buyers, with a full cycle of interaction — from publication to payment and access to content.

• Prompt cards with descriptions, ratings, reviews
• Purchase system and access control to content
• Cart, prices, paid and free prompts
• User cabinet (buyer / author)
• Admin panel for moderation, content management, and user management

Architecture
• Custom platform logic (without ready-made CMS)
• Modular structure (content, sales, payments, users, moderation)
• Optimization for a large catalog (pagination, filters, caching)
• UI in the style of modern SaaS / marketplace with an emphasis on speed and convenience

Technologies and stack
• Backend: PHP (custom engine)
• Database: MySQL
• Database interaction: PDO + MySQLi (prepared statements, secure transactions)
• Architectural approaches: MVC, service layer, repositories
• API integrations: REST approach for modules/payments/cabinet
• Security: protection against SQL Injection / XSS / CSRF, server-side validation, role control

Purpose

The platform is created as a commercial product that allows:
• monetizing AI prompts,
