Different tools for different needs
vLex: per Clio, over a billion documents across 110 jurisdictions (company figure, Nov 2025, LawNext). Vincent AI is its AI assistant. We have not verified its Spanish coverage or found a public price list.
Lexiel: 70,000+ official sources (BOE, CGPJ, CENDOJ, TC, EUR-Lex + 17 LATAM 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.
