Benchmark: accuracy on Spanish law

One test with official answers is the Ministry of Justice's Spanish Bar Access Exam.

Platform	Accuracy	Notes
Lexiel with legal RAG	98.0%	149 out of 152 verified questions (July 2026)
Juztina	Not measured by us	We know of no measurement of it on this exam

Lexiel's result rests on its legal corpus and hybrid search (semantic and keyword).

---

Legal corpus

Lexiel works with 130,000+ official sources from Spain, the EU and several Latin American countries. Legislation is chunked at article level and the corpus is updated periodically.

Indexing at article level retrieves the exact provision, not the whole document, and that shows in the quality of the answers.

Juztina: its Peruvian website does not mention Spanish law; it is geared to the Peruvian legal system and offers labour law agents for Peru, Colombia and Chile (according to its website, checked on 11 November 2026).
