Lexiel vs vLex: legal database vs generative AI, when to choose each (2025)

Different tools for different needs

vLex: over one billion documents from more than 100 countries (company figure, according to its website, checked on 11 November 2026). Vincent AI is its AI assistant. We have not verified its Spanish coverage or found a public price list.

Lexiel: 130,000+ official sources (BOE, CGPJ, CENDOJ, TC, EUR-Lex, and several Latin American countries), full generative AI (drafting, analysis, Q&A), integrated practice management (CRM, VeriFactu billing, client portal). 98.0% (149/152) on bar-exam questions, measured by us with the raw data published at lexiel.ai/benchmark. Price: from €52/month + VAT (all features).

Choose vLex when: you need lower-court case law (AP, TSJ, first-instance), doctrinal Mementos, or international legal comparison. Choose Lexiel when: you want generative AI drafting, integrated practice management, accessible pricing, and citation traceability.

Combined use pattern: Large firms: vLex for deep research + Lexiel for daily AI work and practice management. Small firms that mainly work with legislation, Supreme Court and Constitutional Court case law and drafting may find Lexiel enough; the saving depends on what you pay today and we do not estimate it.
