EU AI Act Classifier
Answer 4 questions and find whether your AI system is prohibited, high-risk, limited-risk, or minimal-risk — plus the obligations that apply to you.
The EU AI Act classifies AI systems into four risk tiers: prohibited (Article 5), high-risk (Annex III), limited-risk with transparency duties (Article 50), and minimal-risk. This tool walks you through the same decision tree an assessor would use.
Does your AI system do any of the following?
These practices are prohibited outright under the EU AI Act (Article 5).
Frequently asked questions
How accurate is this classifier?
The classifier follows the EU AI Act structure closely: Article 5 for prohibited practices, Annex III for high-risk use cases, Article 50 for transparency obligations, and Chapter V for GPAI. It gives you the correct tier for the vast majority of cases, but does not replace legal counsel for edge cases and grey areas.
Do I need a lawyer even after using this?
Yes, for any material deployment. This tool is a fast triage — it tells you which chapter of the EU AI Act applies and what obligations you are looking at. For final placement-on-the-market decisions, obtain qualified legal review.
What if my AI matches more than one category?
The most restrictive tier wins. If any prohibited practice is present, the system is prohibited outright. If any Annex III use case applies, the system is high-risk even if it also triggers transparency obligations.
What is GPAI and why is it treated separately?
General-Purpose AI (GPAI) models — like large foundation models — carry Chapter V obligations regardless of what downstream use case they end up in. If you build such a model, the obligations apply to you as the provider. If you fine-tune or wrap one, the downstream obligations still apply based on your use case.
When do these obligations start applying?
The EU AI Act phases in over multiple deadlines. Article 5 prohibitions applied first (February 2025). Most GPAI obligations began August 2025. High-risk system obligations under Annex III begin August 2026, with the safety-component route on a two-year runway from that date.
How does Zilonex Govern help after classification?
Zilonex Govern re-runs this classification on every model version, tracks the obligations that apply, generates the evidence pack, and gates deployments in CI/CD. Starter is $99 per month for 5 models, Growth is $299 per month for 25 models.
