This web-based tool streamlines prompt engineering for large language models, enabling developers, researchers, and content creators to efficiently test, compare, and optimize prompts across multiple LLM providers. It offers a centralized interface for managing prompts, variables, and model configurations, ultimately improving AI output quality.

How It Works

The application utilizes a React frontend with Material-UI for a responsive, resizable panel layout. It interacts with LLM APIs (currently OpenAI and Anthropic) via axios for HTTP requests. Users can define prompts, manage dynamic variables, save configurations, and compare outputs side-by-side, facilitating iterative prompt refinement.

Quick Start & Requirements

• Install dependencies: npm install
• Start server: npm start
• Prerequisites: Node.js (v14+), npm (v6+).
• API Keys: Requires .env file with REACT_APP_OPENAI_API_KEY and REACT_APP_ANTHROPIC_API_KEY.
• Access: http://localhost:3000

Highlighted Details

• Supports multiple LLM providers (OpenAI, Anthropic).
• Features global and individual prompt modes.
• Enables dynamic prompt generation via variable management.
• Allows saving and loading of prompts, variables, and model configurations.
