Deterministic search
A C++20 engine that examines every document in the corpus and returns a mathematically bounded result set. No approximation, no skipped rows, no silent recall loss.
Engine architectureRegulated industries don't lose because their AI is wrong. They lose because nobody can prove it was right. Winnex returns every answer with a signed record showing the search was exhaustive — and that nothing was skipped.
The problem
Every vector database on the market returns an answer and asks you to trust it. Approximate search skips documents. Nobody knows which ones. When a regulator, a judge, or an auditor asks “did you actually look at everything?”, the honest answer today is: nobody can prove it.
We built the answer to that question.
The platform
Winnex is not a wrapper around someone else's model. It is the retrieval engine, the audit record, and the products built on top of both.
A C++20 engine that examines every document in the corpus and returns a mathematically bounded result set. No approximation, no skipped rows, no silent recall loss.
Engine architectureEach query produces a signed, tamper-evident record: which corpus, which threshold, what was excluded and why. Exportable as a certificate that survives legal review and WORM storage.
Audit architectureTracer-GOV, Tracer-JUS, Tracer-MED and Tracer-GAP put the engine to work in government, legal, clinical and financial triage — each with its own domain model and its own evidentiary chain.

Four products, one engine. Each query returns the answer and a signed record of what was examined and what was excluded — exportable as a certificate an auditor can check without us.
Preprint and benchmark results are published on Zenodo (DOI 10.5281/zenodo.21826158, latest version v4) with the raw results in the open.

Why it matters now
The EU AI Act makes documentation and traceability a legal requirement for high-risk systems. LGPD and GDPR require you to explain how a decision was reached. “The model returned it” stopped being an answer.
Where it runs
The same engine powers four products. What changes is the corpus, the review rules, and the shape of the certificate each domain needs.
Evidence-backed triage with a record of what the model saw and what it ruled out.
WORM-backed procurement and policy review that survives freedom-of-information scrutiny.
Every document examined, every exclusion justified, delivered with a certificate in PDF.
Reconciliation across ledgers where a missed line is a real loss, not a rounding error.
“The question is no longer whether the model is accurate. It is whether you can prove what it looked at.”
The company
Madhava, our search engine, did not start as a research project. It was built to be the retrieval layer of Winnex Maestro, our own business management platform — which means it has been answering real commercial queries under load since day one.
Winnex Brasil Soluções Empresariais LTDA-ME is a Brazilian deep-tech company. Our engineering is published, our benchmarks are reproducible, and our models run on infrastructure you control.

We run a technical walkthrough on your own corpus — your documents, your questions. You leave with the recall numbers and a signed certificate, not a slide deck.
