⚡ Run it live with your own API key no key set

Your key is held in memory for this session (kept for this tab only if you tick the box) and sent only to the provider you choose, directly from your browser. This site has no backend server — you can confirm it in your browser's Network tab: requests go only to the provider, never to this site. Live runs use small, fast models with hard token caps; a typical run costs well under $0.01, billed to your own account.

Honest limits: no website can protect a key from a compromised browser or malicious extension. Use a key with a spending cap, and revoke it after playing if you like.

How it’s engineered

Schema-first prompting: the JSON shape is part of the contract, and production adds a validator that rejects and retries malformed output.
Typed identifiers (IBAN, VAT, invoice number) are what make extraction pipeline-ready instead of demo-ready.
This pattern replaced 40+ hand-written parsing rules in one of my enterprise systems.
