Input text

Using auto-detected structure

Output

How it works

Not a language model. No prompt engineering. No non-determinism.

Deterministic — same input always produces the same output
Grounded — every field is traceable back to the input text
Fails closed — returns an error rather than an invented value
Fast — no external API call, no inference latency

No more broken pipelines

Zero parsing errors
No hallucinated fields or values
Fails closed — returns an error instead of bad data

Built for production

Extract structured data from form submissions, tickets, bookings, invoices, and any freeform text — reliably, without an LLM in the loop.

Simple REST API

POST https://api.triaia.com/v1/structured/generate

{
  "input": "John bought 2 apples for $5",
  "schema": {
    "type": "object",
    "properties": {
      "customer": { "type": "string" },
      "item":     { "type": "string" },
      "quantity": { "type": "number" },
      "price":    { "type": "number" }
    }
  }
}

→  { "output": { "customer": "John", "item": "apples",
                 "quantity": 2, "price": 5 }, "valid": true }
