How the EU AI Act risk classification works
The Regulation asks four questions in a fixed order, and each answer decides whether the next one matters. This compliance checker walks the same sequence and shows which provision drove each conclusion.
- Is the system in scope at all? Article 2 catches providers placing an AI system on the EU market wherever they are established, and providers and deployers outside the Union whose system output is used in the EU. Military, national security and purely personal use are excluded. If you only need this question answered, the scope finder by industry is faster.
- Is it a prohibited practice? Article 5 bans ten practices outright. If one applies, nothing further is assessable: the system cannot be placed on the market or used, and the exposure is up to €35 million or 7% of turnover.
- Is it high-risk? Two independent routes: a safety component of a product covered by the Annex I harmonisation legislation, or a use case in one of the eight Annex III areas. The routes carry different deadlines: 2 August 2028 and 2 December 2027 respectively.
- Do transparency duties attach? Article 50 applies regardless of tier where a system interacts with people, generates synthetic content, produces deep fakes, or infers emotion or biometric categories.
What the compliance checker produces
A classification for each tier with the provision that produced it, a list of the obligations that follow for your role, the dates each obligation applies from, and the open questions that need a human answer before the classification can be relied on. The result can be exported as a dated assessment record for your compliance file.
Free, and nothing leaves your browser
Most EU AI Act checkers ask for a work email before they show you the result. This one does not. The questions are free to answer, the classification appears on the page, and the PDF is generated in your browser rather than on a server, so the answers you give about your systems are not transmitted to produce it. Run it as many times as you have systems.
Checking more than one system
The checker screens one system per run, which is the right unit: classification is a property of a system and its purpose, not of an organisation. For a portfolio, the usual order is to build the inventory first, then run the screen per system and keep each record. The 31-step compliance checklist sequences that work, the readiness view shows which duties already bind you, and the sector guides cover the Annex III areas in detail. If you would rather not do it alone, Holistic AI will run the assessment with you.
What it does not do
It is not a conformity assessment. A conformity assessment under Article 43 is a formal procedure that in defined cases requires a notified body, and it cannot be completed by answering questions. The tool is a preliminary screen and an evidence-planning aid: useful for scoping the work and for showing your reasoning, not for concluding it.
