The Challenge

You need AI-generated content, but how do you know if your prompts are actually good? Teams waste time rewriting prompts, can't track what works, have no idea what they're spending on AI, and lack proper moderation to prevent inappropriate content from slipping through.

Beyond just writing prompts, every team member has their own approach with no version control or collaboration. There's no way to compare different AI providers, no analytics to understand usage patterns, and no systematic way to share what works across the organization.

The Solution I Built

A platform where teams can create, optimize, and manage AI prompts while comparing results across multiple providers. Within seconds, see side-by-side responses from Claude Sonnet 4.5 and GPT-4o, with comprehensive cost tracking showing exactly what each request costs.

Beyond just prompts, the platform includes a complete team collaboration experience:

  • Compare AI responses side-by-side - See Claude vs ChatGPT results instantly
  • Track every version - Full history with one-click restoration
  • Share the best prompts - Community library with filtering and discovery
  • Know your costs - Real-time tracking of every AI request with per-token pricing
  • Moderate safely - Automated 11-category content moderation with review workflows
  • Analyze usage patterns - Comprehensive admin dashboard for team insights

What Users Can Do

Why This Example Matters For Your Business

You might be thinking: "I don't need a prompt management tool—I need a customer analytics dashboard" or "I need a content moderation system" or "I need a team collaboration platform."

That's exactly the point. This project demonstrates transferable skills:

  • Building admin dashboards - Real-time analytics, filtering, data visualization with charts and trends
  • Content moderation systems - Automated scoring, review queues, approval workflows
  • Multi-provider API integration - Anthropic, OpenAI with intelligent routing and error handling
  • User analytics & tracking - Comprehensive logging, cost tracking, trend analysis
  • Team collaboration features - Sharing, discovery, role-based access control
  • SaaS economics - Per-token cost tracking, usage analytics for sustainability planning

If I can build a prompt management platform with dual-AI comparison, moderation workflows, and cost analytics—I can build your customer dashboard, team collaboration tool, or content management system. The industry changes, the skills don't.

Technical Implementation Details

For developers and agencies interested in the technical architecture, tools, and lessons learned

Why I Built This

I wanted to demonstrate my ability to architect a complete SaaS platform while solving a real problem: AI prompt quality and cost management. The multi-AI comparison serves two purposes: it helps users find the best AI for their needs, and it showcases my ability to integrate multiple complex services with intelligent routing.

The comprehensive admin dashboard came from research showing that businesses need visibility into AI spending and content safety. Building moderation workflows, cost tracking, and team analytics from day one demonstrates production-ready thinking and business awareness.

I chose to implement OpenAI's 11-category moderation API because content safety is critical for any user-generated platform. The automated scoring system (auto-publish below 0.3, review queue 0.3-0.8, auto-reject above 0.8) shows I understand how to balance automation with human oversight.

Project Overview

PromptBuilder enables users to create, optimize, and manage AI prompts while comparing results across multiple providers. Users can track version history, share prompts with the community, and monitor costs with per-token precision.

This project demonstrates my ability to architect a full-stack SaaS application with proper authentication and data security, integrate multiple AI providers (Anthropic, OpenAI) with 11 model variants, build comprehensive admin tools with analytics, advanced logging, and content moderation, implement Row Level Security policies and role-based access control, and deploy production-ready applications with proper monitoring and cost tracking.

My Role: Technical architect and builder using AI assistance. I made all architectural decisions (database schema design, API structure, feature prioritization, tech stack choices) and configured all services, while using AI tools to assist with code implementation.

Technical Architecture

Dual AI Provider Integration

Side-by-side comparison of Claude Sonnet 4.5 vs GPT-4o. Support for 11 AI models across 2 providers with parallel execution, error handling, and intelligent fallback mechanisms.

Comprehensive Cost Tracking System

Per-token pricing precision for every request. Real-time cost calculation across all providers with admin analytics showing spending patterns, usage trends, and provider comparison for data-driven optimization.

OpenAI Content Moderation Integration

11-category automated safety scoring with intelligent workflow: scores below 0.3 auto-publish, 0.3-0.8 require admin review, and above 0.8 face automatic rejection with user notification.

Complete Version Control System

Full history tracking for every prompt iteration with one-click restoration to any previous version. 26 database migrations document the schema evolution and demonstrate proper database management practices.

Role-Based Access Control

Clerk authentication with JWT session claims for admin access. PostgreSQL Row Level Security policies ensure users access only their data. Admin-only routes protected by middleware.

RESTful API Architecture

34 well-organized API endpoints covering all functionality. 8 core database tables with proper relationships and constraints. Advanced filtering and search across all logged data with CSV export capability.
