FAQ: Perplexity AI vs Lexiel

Is Perplexity AI reliable for Spanish law queries?

Perplexity AI is a general-purpose AI without a verified Spanish legal corpus. It cannot access BOE or CGPJ, may invent non-existent articles or rulings (hallucinations), and does not verify citations against official sources. Lexiel scores 99.3% on the Bar Exam (144/145) and 98.4% on the Judiciary Exam (253/257) through its specialised legal RAG.

Is Perplexity AI GDPR-compliant for law firms?

Perplexity AI processes data outside the EU by default. For a law firm, this raises risks under GDPR (Art. 28) and may compromise attorney-client privilege. Lexiel hosts all data on European servers (Germany) and does not use user data to train models.

Can Perplexity AI draft court briefs with BOE citations?

Perplexity AI can generate legal-looking text but cannot verify that citations are real. The risk of presenting a non-existent ruling or article in court is significant. Lexiel generates briefs with citations verified against BOE and 1,868 CENDOJ rulings, with reference to the original source.
