Frequently Asked Questions

Is the AI JSON generator really free?

Yes, absolutely. Our tool is free to use, powered by leading open-source AI models. This allows us to offer powerful generation capabilities at no cost, subject to a fair daily rate limit to ensure availability for all users.

Can I create complex, nested JSON?

Yes. The AI excels at handling complex requests. You can ask for nested objects, arrays of objects, and mixed data types. The more specific your prompt, the better the result. For example, try asking for "An array of 2 blog posts, each with a title, author object (with name and email), and an array of tags".

Is the generated JSON guaranteed to be valid?

While the AI has a very high accuracy rate, it can occasionally make a mistake. That's why we built this tool to seamlessly integrate with our core validator. After generation, the code is instantly checked for validity, and any errors are highlighted for you to fix immediately.
