As answered by people managing HackerRank and ComplianceAgent.
ComplianceAgent's answer:
It is free, instant, and specific. Whole-Act scoping tools give you broad orientation; this checker goes deep on Article 50 transparency obligations specifically — and gives you a written result you can keep. No account, no sales calls, nothing stored.
ComplianceAgent's answer:
Any organization that builds or deploys AI systems reaching users in the EU — SMEs, law firms, agencies, healthcare, finance, manufacturing, nonprofits, and government contractors.
ComplianceAgent's answer:
Article 50 transparency obligations apply from August 2, 2026, and most scoping tools cover the whole Act at a shallow level. ComplianceAgent built a free checker that goes deep on Article 50 specifically: five plain-language questions, an instant deterministic result, and nothing stored.
ComplianceAgent's answer:
The checker is a single static page served from Cloudflare. Its logic is fixed rules in plain JavaScript — no AI model, no backend, no database, no login.
ComplianceAgent's answer:
The checker is deterministic — every answer maps to a specific paragraph of EU AI Act Article 50, so the article numbers and dates you see are looked up, not generated by an AI model, and cannot be fabricated. Five plain-language questions, instant on-page result. No account, nothing stored.
