Who Owns What Under the AI Act?

A plain-English guide to the AI Act roles, because the same system can create very different duties depending on what your company actually does.

The role question is one of the easiest places to get lost. Buying an AI tool does not automatically make you its provider. Building, rebranding, substantially changing, importing, distributing, or deploying a system can put you in different legal positions.

Leave knowing / Know which role needs deeper review

The four common roles

Translate the legal nouns into normal work.

Provider

You develop an AI system or model, or have one developed, and place it on the market or put it into service under your name or trademark.

Deployer

You use an AI system under your authority in a professional or organisational context. For many companies buying and using AI, this is the role to examine first.

Importer

You place an AI system on the EU market when the provider is established outside the EU. The legal chain matters, not just where the software runs.

Distributor

You make an AI system available in the EU supply chain without being the provider or importer.

The trap

Your role can change.

A company can begin as a deployer and move closer to provider obligations if it puts a system on the market under its own name, makes a substantial modification, or changes the intended purpose in a way the Act treats as significant.

That is why “we use Vendor X” is not enough information. You need to know what your organisation changed, branded, integrated, controlled, and put into service.

The contract says who sold it. The facts say what role you are playing.

Examples
