Your AI answers. LIA Engine checks the answer against your data and the rules of the request, fixes what can be computed and returns a signed certificate anyone can verify. What can't be verified is flagged, never certified. OpenAI-compatible API: change one URL. 50 free verifications.

Hi Product Hunt! I'm Walter, from Argentina.
I built LIA Engine because I kept seeing AI produce invoices and spreadsheets that looked perfect and were wrong: a VAT amount with two digits swapped, a total that skipped a row, a date like February 31. And it says it with total confidence.
LIA Engine sits between your app and the AI you already use (OpenAI, Claude, Gemini, Groq, DeepSeek and more). Your AI still does the work. LIA checks the answer against your data and the rules of the request, fixes what can be computed, and returns a certificate signed with Ed25519. Anyone can verify it with a small MIT-licensed verifier, no account needed. If something can't be verified, it isn't certified and you get the reason.
Today it covers invoices and VAT, Excel and PDF tables, photos of receipts, data extracted from documents, diagrams and electronic circuits. You connect it by changing one URL in any OpenAI-compatible client, and you keep your own AI key.
There's a free trial with 50 verifications, no card. I'd love your feedback, especially: which task would you want certified next?
