Radau tiesą.
Search EU & Lithuanian law
Ask in English or Lithuanian — with or without diacritics. Radau finds the passage that answers, shows tables as tables, and opens the official text at the right place. v01.1 covers DORA, NIS2 and the animals-in-science rules (EU Directive 2010/63 + LT B1-866), each in EN and LT.
Retrieved passages are not legal advice. Always cite the official OJ text (CELEX) and verify against EUR-Lex before relying on a provision.

How it works
- Prepared from the official texts. Each act is split into articles, recitals and annexes; tables are rebuilt from the original EUR-Lex / e-seimas HTML as real tables (rows and columns), and every passage links back to its source.
- Reads your question. Words are matched in any grammatical form (Lithuanian and English stemming, diacritics optional). The question type — deadline, definition, penalty, scope, authority, table/size… — is detected by keywords and by Jev, a fast decision model.
- Finds candidates. BM25 keyword ranking over the selected documents, plus passages that answer that type of question, plus the most relevant 1-hop citations.
- Judges the answer. Jev re-ranks the top results on the full passage and picks the best part of each for the card; the answer sketch quotes it (e.g. “within 24 hours … within 72 hours”). An AHP–TOPSIS re-ranker is being tested on the Beta lane (beta.radau.tiesa.tech) and is not part of this site yet.
- Shows you the source. Tables stay tables; “Read in document” opens the whole act with a hit column (two acts side by side to compare); “Original ↗” opens EUR-Lex / e-seimas at that place. Passages are not legal advice — cite the official text.
