Which AI Is GDPR Compliant? The 6-Point Test for Any Vendor [2026]

No AI tool is GDPR compliant on its own. GDPR compliance is a property of how your company uses a tool, not a label a vendor can print on its website: you are the controller, the vendor is your processor, and the question is whether the tool lets you meet your duties. So the useful question is not which AI is GDPR compliant, but which AI passes six checks you can run on any vendor in an afternoon.

This guide gives you that test, runs the common options through it, and shows how to use AI in a GDPR compliant way from the first user on. It builds on the GDPR itself and on the guidance of the German data protection authorities on AI, which was written for exactly this situation: a company that wants to select and use an AI application.

Because the GDPR puts the duties on the controller, which is you. Under Article 28 the vendor processes personal data on your behalf and has to sign a data processing agreement, but the legal basis, the purpose, the records of processing, the impact assessment and the proof that all of it works stay with your company; Article 5(2) calls that accountability.

A vendor can make this easy or impossible. Easy means: data stays in the EU or goes only to a country or company with an adequacy decision, the models behind the tool do not train on your inputs, the tool only sees what each user may see, and every access is logged. Impossible means: you cannot find out where a prompt went, which model answered it, or who asked about a customer last Tuesday. The German authorities list exactly these points in their guidance on AI and data protection, from the purpose of the use to the question whether the system is open or closed.

Run these six checks on every tool before personal data goes in. The first two are about where data goes, the next two about what the AI can see, the last two about what it does and what is left behind. They follow the six components of an AI operating system for companies, because a tool that has none of those components usually fails the matching check.

None of them is compliant by default, and most business tiers can be used compliantly if you sign the data processing agreement and close the gaps below. Free consumer tiers are the exception: they are built for private use and are not the place for customer or employee data. The table names the weak spot to check first for each option and links our detailed reviews.

Two things the table cannot show. First, a US vendor with EU hosting still has a US parent, so ask how it handles access requests from US authorities; the European AI data sovereignty guide explains why. Second, the contract matters as much as the product: the DPA checklist for AI tools lists the 12 clauses to read before you sign.

Not for company data. A free tier can be fine for texts without personal data, but as soon as names, customer details or anything about employees go in, you need a data processing agreement, and free consumer tiers usually do not offer one. The cheapest compliant route is a paid business tier or an EU platform without a seat minimum, or a free trial of one before you commit.

The European Data Protection Board made a second point relevant here in its Opinion 28/2024 of 18 December 2024: whether a model itself was trained lawfully can affect how it may be used. That is one more reason to know which models sit behind a tool, the second check in the test above.

Choosing a tool that passes the test is half the work. The other half is what your company documents and decides, and it takes days, not months.

Teamo AI was built around this test for companies with 5 to 200 employees. It runs in the EU with a data processing agreement, calls several model providers with a training exclusion for each, reads live from the tools you already use (Slack, Teams, Jira, Notion, HubSpot, Pipedrive, your calendar) instead of copying them, enforces permissions down to single records, lets agents write only after a person approves, and keeps three separate audit logs for six months that you can export.

It costs 9.97 euros per user and month plus usage-based AI credits, with no seat minimum, and a one-time setup of 500 to 2,000 euros that includes a personal setup with your team. You can run all six checks yourself in the 14-day trial, including the restricted test user.

The question which AI is GDPR compliant has no list as its answer, but it has a test. Six checks separate a tool you can use with company data from one you should keep away from it, and seven steps on your side turn a good tool into compliant use. Run the test before the pilot, not after the first complaint, and compare the results side by side with the compliance software comparison if you also need tooling for the documentation.
