This tool validates LLM-generated JSON against a specified schema, providing repair prompts if errors are detected, thereby preventing application crashes and improving user experience. The tool is available as a pay-what-you-want download on Gumroad and aims to enhance the reliability of LLM outputs for developers. AI
