Since 2 August 2026  Article 50 applies

AI register under the EU AI Act — keep track of the AI your company uses.

The evidence layer of your AI governance: AI CostGuard documents your AI tools, monitors what vendors state, and turns that into traceable records for GDPR and the AI Act — every statement with source, quotation and retrieval date. It rests on KI-Radar: a directory of 270 AI tools, checked on data processing under Art. 28 GDPR, processing location, training on customer data, and certifications.

The problem

Four problems. One answer.

AI use is opaque

AI tools arrive through the business units, not through IT. Whoever has to count them starts from zero.

Vendors change what they say

A certification disappears, a training clause appears — usually without notice.

Evidence is missing

“We checked that back then” does not survive an audit. What is asked for is what the assessment rested on, and when.

New obligations

GDPR, the AI Act, Article 50 — and each obligation needs a document somebody signs.

In four steps

How AI CostGuard works

From the first list to a record ready for signature — without you maintaining a database.

1
AI register

Enter tools or upload a list — an invoice will do. Purpose, owner and legal entity alongside.

2
Matching

Each tool is linked to our verified directory. The ratings are there at once — you research nothing.

3
Monitoring

If a vendor changes something about one of your tools, you get a notice with before and after.

4
Records

Every quarter a dated document per entity, with quotation and source for every statement. At the touch of a button.

AI governance

What AI governance means here.

Anyone deploying AI carries six duties that cannot be delegated — only evidenced. What the register contributes to each:

1
Know what is in the house

A register per legal entity: tool, purpose, department, and the person who answers for it. Also from an uploaded list or an invoice.

2
Determine role and risk class

Provider or deployer, and which class of the AI Act the system falls into. Recorded per system, not as a blanket verdict on the company.

3
Provide transparency · Art. 50

Which of your systems need a notice, whom the duty falls on, and the sentence that belongs on the page.

4
Ensure AI literacy · Art. 4

Record per system whether the people working with it need training — and what happened about it.

5
Vet the processor · Art. 28 GDPR

DPA, processing location, training on customer data and certifications — evidenced per tool, with source and date, checked daily. This is the part everyone else researches themselves.

6
Account for it · Art. 5(2) GDPR

A dated quarterly record with a checksum over the underlying facts. Every earlier state remains traceable — including the one that no longer holds.

And what it does not do.

Governance is more than evidence. The rest is yours — or another tool's.

No approvals

There is no request-and-approval workflow for new AI tools. Whoever needs one runs it where the rest of procurement runs.

No policies

We do not manage policies or works agreements. We evidence what your tools commit to; what you make of that is yours to decide.

No high-risk duties

Conformity assessment, technical documentation and the design of human oversight under Annex III are outside this register. It tells you which systems might be affected — not how to discharge the duties.

No incident reporting

Reports under Article 73 do not run through us. What we provide is the documented state before.

In short: we are the evidence layer of your AI governance, not the decision layer. Decisions are made at your end — evidence is kept here.

Our chain of evidence

We do not rate opinions. We document demonstrable statements.

Other directories hand you a verdict. We hand you the verdict and the source it came from — verbatim, as of the day of retrieval. The methodology in detail →

1 · Source

Trust centre, data processing agreement, privacy policy — from the vendor itself only, never second-hand.

2 · Quotation

The deciding statement is recorded verbatim. You read the sentence the rating rests on.

3 · Retrieval date

Every statement carries the day we last looked. Not “current”, but a date.

4 · Archive

The page is stored unchangeably. Even if the vendor rewrites or deletes it tomorrow.

5 · Assessment

A person decides and gives reasons. The predecessor stays readable — nothing is quietly overwritten.

6 · Record

Your document, dated, with quotation and reference. In six months it still says the same.

What does your AI really cost?

No expertise needed. Pick your use case, the model and your volume — the calculator converts tokens, minutes and credits into euros and shows the hidden costs that appear on no invoice.

Plans

Looking things up is free. The maintained register is not.

The directory is open to everyone, no sign-up. What you pay for is the work on it: taking in your tools, keeping them current, and turning that every quarter into a dated document that survives an audit.
