We build the semantic layer
that global trade runs on.
There are two ways to work with us: grab the tools and run with them yourself, or bring us in to build the layer around your own data.
Tools
Open-source and licensed engines for classification, ingest, and query — take what you need and go.
Browse the tools →Services
Ontology development and advisory work, scoped around whatever you're actually dealing with.
How we engage →This is the actual engine, drawn as itself — the swirl is the model, the little dot is one classification finding its way through it.
Tools
Each one ships as a standalone tool, built on the same engine underneath. HS tools has been around the longest — the rest are catching up, built the same way.
HS tools
Deterministic HS/HSN classification, with the reasoning shown — every code traces straight back to the tariff text, not a confidence score you're left to just trust.
Open sourceRx tools
Ingests pharmacopoeial and regulatory data and lines it up against a shared therapeutic ontology. Licensed per deployment.
LicensedRoute tools
Queries preferential trade agreements and rules of origin, then hands back the duty-optimal route — hosted, so there's nothing for you to install.
HostedServices
A practice, not a catalogue — every engagement gets scoped around what you're actually working with, not a generic package.
Ontology development
We sit down with your product, drug, or trade domain and model it as a formal ontology — something your systems can query and your team can actually audit.
Knowledge graph builds
We take whatever you've already got — catalogues, tariff schedules, regulatory filings — and turn it into a queryable graph, wired into the systems you already run.
Advisory and training
Ongoing guidance for teams building this kind of infrastructure themselves, plus hands-on training so your engineers aren't stuck waiting on us.
Live demo
Query a real graph, right here in the browser — shown, not just claimed.

About
Ontinai is a small, opinionated semantic technology practice — we'd rather build a real ontology than bolt a chatbot onto one. We build the tools first, for ourselves and in the open, then bring the same engine into engagements where a team needs the layer built around their own data — trade, pharma, and whatever regulated work comes after that.
Get in touch
Tell us what you're working with — a demo, a question, or an engagement you're scoping — and we'll get back to you.
The tools are open. The reasoning is visible. That's really the whole pitch.
