• "Find EU regulations about artificial intelligence from 2024"
• "Show me the full text of the AI Act (32024R1689)"

• "Which documents cite the Digital Services Act?"
• "Search for directives about renewable energy"
• "Get the consolidated version of Regulation 2016/679 (GDPR)"

Features

• 6 specialized tools for searching, fetching, and analyzing EU legal documents
• EuroVoc thesaurus search -- find documents by EU taxonomy concepts
• Consolidated versions -- retrieve the latest in-force text of regulations, directives, and decisions
• Citation graph -- explore which documents cite or are cited by a given act
