Yes. CaseTag is currently in open beta and every feature is fully accessible at no cost. We may introduce paid tiers in the future as the database grows, but early users will always be the first to know and will receive preferential pricing.
CaseTag lets you explore concept threads — named doctrinal lines such as "AEC Test Evolution" or "Essential Facilities Doctrine" — that group related cases together. The system generates a chronological timeline showing how legal principles developed across rulings. Cases can also be manually linked with relationship notes.
Our database includes judgments and decisions from the Court of Justice of the European Union (CJEU), the General Court, the European Commission, and selected national court decisions that are significant for EU law enforcement.
AI tools can generate case summaries, but they can hallucinate case numbers, miss nuances, and produce inconsistent analysis. CaseTag is curated by EU competition law specialists. Every Master File is verified, every doctrinal connection is deliberate, and the database is structured specifically for legal research — not general-purpose conversation.
We monitor EUR-Lex, the CJEU's case law portal, and the Commission's decision register regularly. New cases are added as they are published, with landmark decisions prioritised for detailed Master File analysis.
