Hi HN,<p>I've been working on a dead simple prompt engineering canvas that allows chaining prompts in a visual way.<p>I've built a product on top for creating hackerrank/leetcode style challenges where solutions compete on correctness, latency, token usage and cost.<p>I'm hoping the main product can become a prototyping and even production-quality tool for building prompt chains.<p>Perhaps the arena product will become an entry point for software engineers learning about building with LLMs and how multiple prompts work in production.<p>Thanks for looking,<p>-- Michael
