Diarium vs Lexiel : law firm management vs integrated legal AI

Diarium is a popular Spanish law firm management software among solo lawyers and small firms: cases, calendar, time tracking and billing. However, it completely lacks legal AI, a verified legal corpus (BOE, CENDOJ, CGPJ) and a drafting assistant. Lexiel integrates everything Diarium offers plus generative AI specialised in Spanish and Latin American law (99.3% Bar Exam, 98.4% Judiciary), client portal, procedure engine and Verifactu invoicing, from €69/month.

FAQ: Diarium vs Lexiel

Can Diarium be used as law firm management software in Spain?

Diarium is a generic tool that some firms manually adapt. It lacks a Spanish legal corpus, procedural deadline calculation, Spanish VAT/tax invoicing, and any legal specialisation. Lexiel is designed specifically for Spanish lawyers, with everything integrated from day one.

Does Diarium have legal AI?

Diarium may have generic AI features, but it has no Spanish law corpus (BOE, CGPJ, case law), does not verify legal citations and cannot draft procedural briefs. Lexiel combines practice management with specialised legal AI scoring 99.3% on the Bar Exam (144/145) and 98.4% on the Judiciary Exam (253/257).

How does Diarium's pricing compare to Lexiel?

Diarium requires manual setup, third-party integrations and potentially additional licences for legal functionality. Lexiel from €69/month includes legal AI, CRM, case files, invoicing, client portal and procedure engine. All in one, no extra modules.
