🎯 What Makes This Special¶

Intelligent Enhancement Workflow¶

Unlike basic prompt managers, this platform uses AI to analyze your prompts and generate context-aware questions to improve them. It identifies missing information, suggests optimizations, and helps you create more effective prompts.

Provider-Agnostic Design¶

Write once, render everywhere. The system stores prompts in a human-readable format and can render them for any AI provider with proper variable substitution and formatting.

Real-time Collaboration¶

Multiple users can edit prompts simultaneously with live updates, conflict resolution, and comprehensive audit trails.

Enterprise-Grade Security¶

Zero npm security vulnerabilities
JWT authentication with refresh token rotation
Role-based access control (RBAC)
AES-256-GCM encryption at rest
TLS 1.3 for all communications
