Ontology modeling, guided by Anchor

What would you like to model?

Describe a business domain in your own words. Anchor will clarify the model, build valid ORM, run the NORMA validator, and visually check the exact draft before you save.

Use a workspace ontology Build from models you already have access to in Anchor.

Anchor searches only ontologies available in this workspace.

Draft 1

This draft was visually checked. If the layout looks off, say what to change. Standing visual preferences are saved for later models. Nothing changes in your ontology library until you approve it.

xAI grok-4.6 Click Send to run this prompt

Your message and selected or retrieved workspace ontology content are sent to the workspace-configured external AI provider (xAI) for processing.

First draft is capped at 6 facts so the diagram stays readable. If it looks wrong, we revise that core. If it looks right, we add the next facts.

CRM

Accounts, contacts, and opportunities for the revenue team.

Ask Anchor talks to

Your model lives in too many places

The file exists. The gap is between the model and everyone who needs it.

  • Only one person can open it

    The current model sits in a desktop tool on somebody’s machine.

  • The file is the version

    Work arrives as a zip. History lives nowhere.

  • The agent invents your terms

    It guesses what “account” means on your floor, then acts on it.

Link models into one hierarchy

Nest an ontology under its parent and the tree stays legible. People see where a model sits at a glance.

Agents read the same chain. When one opens CRM, it knows Enterprise Core sits above it.

Humans and agents share the same map.

Enterprise Core

Shared vocabulary for the whole company.

Share it without losing control

Private to your workspace or public on Explore. Flip it in the share sheet.

Embed the live diagram, copy Markdown, or invite a teammate without leaving it.

The link always opens the current model.

CRM

Anyone can open this link. The model shows on Explore.

Public link

Agents read the model you approved

Point any MCP client at Anchor and it reads the current model. Your approved terms, never a guess.

Syntaxia runs on Anchor

Syntaxia is the harness. The model is the anchor. Our consultants feed and maintain client ontologies in Anchor, and Anchor serves the current model back to every agent in the harness.

That is the loop we build for clients: one place where the model lives, and agents that never guess.

Questions we hear a lot

Can I keep a model private?

Yes. Individual gives you unlimited private models in your personal workspace. Unlisted links stay off Explore. Team is for people you invite.

How do agents read my model?

Over MCP, straight from Anchor. Agents read the current model and use the terms you approved.

What files can I upload?

ORM, RDF, OWL, SKOS, JSON-LD, YAML, and Turtle. Upload what you have, or start from English in Ask Anchor.

Which AI model does it use?

Yours. Bring your own key for Anthropic, OpenAI, or xAI and switch models whenever you want. We own the harness and rent the model, so you are never locked to one.

Does Anchor get better as I use it?

Yes. It keeps a memory of your style and your domain: ref mode, layout preferences, and the vocabulary you approve. Every draft starts from how you already model.

Is Free actually free?

Unlimited public models. No card to publish. Pay when the work has to stay private, or when you need a team of ten.

Do I still need NORMA?

Only if a client still wants the desktop file. Drawing boxes in NORMA is a tax. Ask Anchor writes and checks the ORM, and you can download the .orm.
