We build semantic networks for global trade.
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
Licensed and hosted 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.
LicensedPharma 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.
HostedPricing
Perpetual edition licensing, matched to the five-year HS cycle — not a per-query meter.

Enterprise & government
India prices apply only to Indian entities invoiced in rupees with a valid GSTIN, and exclude 18% GST. Data & OEM licensing and training programmes are quoted separately — get in touch.
Services
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 — classes, relationships, and the rules that connect them, not a spreadsheet of tribal knowledge sitting in one analyst's head. That starts with structured workshops alongside your subject-matter experts, moves through a working draft we validate against real historical decisions, and ends with a documented ruleset your own team can query, audit, and maintain — every entry backed by a rule trace, not a black box you have to take our word for.
Knowledge graph builds
We take whatever you've already got — catalogues, tariff schedules, regulatory filings, years of accumulated spreadsheets — and turn it into a single queryable graph, wired into the systems you already run. That means mapping your existing data onto the ontology, resolving the inconsistencies that always surface once things are actually connected, and standing up a query layer so your team — or your existing tools, over the API — can ask real questions of it instead of hunting through files by hand.
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. We review modeling decisions before they calcify into technical debt, pair with your team through the genuinely hard parts, and run structured training sessions so ontology work becomes a skill your organization owns outright — not a standing dependency on an outside vendor.

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. Prefer a dedicated page? Talk to us works too.
The tools are open. The reasoning is visible. That's really the whole pitch.
