jsonAI

jsonAI is a hosted tool for people who keep getting data in the wrong shape. You describe the JSON you want once, as a schema, and the service keeps that schema behind a private API endpoint. Every request you send to the endpoint carries raw input: an email body, a scraped product page, a chat transcript, a line of copied text. The AI reads the input, fills in the fields your schema defines, and returns structured JSON.

The appeal is that you skip writing a parser. There's no regex to maintain and no prompt to paste into an API call every time a new data source shows up. A schema you build once does the work for every later request, which matters when the input format changes weekly and the output format doesn't.

The catch is that this is an AI step, not a deterministic one. Fields can come back empty or slightly off when the source text is thin, and you still pay for tokens on every call. It suits pipelines where a human or a JSON validator checks the result. It also suits people who already know what a JSON schema generator should produce, because the schema you write decides the quality of everything downstream.

One practical note before you sign up. The jsonai.cloud domain now redirects to a companion online JSON viewer, so confirm the hosted endpoints are still live for your account before you put them in a production path.

Getting Started

1. Create an account on the site. The free plan starts without a credit card.
2. Open the schema editor and define your fields: name, type, description, and which ones can be empty. Descriptions matter most, since the model reads them to decide what goes where.
3. Test the schema against sample input in the browser, then save it. Saving produces the API endpoint you'll call.
4. Send requests from your code or a no-code tool, then check the returned JSON against your own rules before it lands in a database.
