What is PromptEngine?
Welcome to PromptEngine - a powerful Rails engine for managing the AI prompts your application uses.

Why PromptEngine?
Managing AI prompts in code is painful. Every change requires a deployment, testing is cumbersome, and non-technical team members can't contribute. PromptEngine solves these problems by providing:
- Central Management - All prompts in one place
- Version Control - Track changes and restore previous versions
- Team Collaboration - Non-technical users can manage prompts
- Testing Tools - Validate prompts before production
- Rails Integration - Works seamlessly with your Rails app
Core Features
Create and organize AI prompts with a powerful template system. Supports multiple AI providers including OpenAI and Anthropic. - Organize prompts by category - Set system messages and model configurations - Define reusable templates - Control prompt status (draft, active, archived)
Never lose a working prompt again. PromptEngine automatically versions every change with full history tracking. - Automatic versioning on save - Compare versions side-by-side - One-click restoration - Change descriptions for context
Test prompts with real AI providers before using them in production. See actual responses and iterate quickly. - Live testing interface - Multiple model support - Token counting - Response streaming
Build dynamic prompts with variables that are automatically detected and validated. - {{ variable }} syntax - Type inference and validation - Default values - Complex types (arrays, JSON)
