How it works
From draft to
production-ready
A systematic approach to prompt engineering that helps you ship better prompts, faster.
Write your prompt
Start with your base prompt. Use variables, system instructions, and context templates to create flexible, reusable prompts.
Create variants
Branch your prompt to test different approaches. Try new instructions, adjust tone, or experiment with formatting.
Test & compare
Run your prompts against multiple LLMs via OpenRouter. Track tokens, cost, latency, and output quality side by side.
Promote the best
When a variant outperforms, promote it to your new base. Keep a full history of what worked and why.
