What Judex does
Judex is a Brazilian legal technology SaaS that provides an integrated AI platform for lawyers, law firms, corporate legal departments, and government entities operating under Brazilian law. Its core products are Editor de peças (an AI document editor with 80+ specialized templates across 24+ practice areas including Civil, Labor, Criminal, Tax, Family, Social Security, Corporate, Real Estate, Consumer, and Corporate law), Assistente Jurídico (a chat-based legal research assistant that retrieves real court decisions with verifiable citations), Prazos e publicações (OAB-linked automated monitoring of official court journals and CPC-compliant deadline calculation), and Processos (case import and real-time movement monitoring). The platform's technical foundation is a proprietary jurisprudence database indexing millions of real acórdãos from STF, STJ, TRFs, TRTs, and state courts, combined with RAG-based retrieval and integration with third-party generative AI providers (Anthropic Claude, OpenAI, Google Gemini). Sub-brands include Judex Juri (standalone jurisprudence search) and API de Jurisprudência (a REST API serving developers and government systems).
The company operates a product-led growth motion anchored by a 7-day no-credit-card free trial and three SaaS tiers: Professional at R$99/month for solo lawyers, Escritório at R$579/month for small firms (up to 10 users), and a custom-priced Escritório Plus for large firms and enterprise customers. Revenue also derives from usage-based AI credit consumption bundled into plans, with monthly credits expiring after 30 days and annual after 364 days. Distribution is direct and digital (website, self-serve app, content marketing, SEO targeting practice-area keywords, LinkedIn and Instagram), supplemented by demo scheduling and direct sales for enterprise/API prospects. Judex is registered as JUDEX LTDA. (CNPJ 66.745.737/0001-41), headquartered in Curitiba, Brazil, with reported scale of 12,000+ lawyers and 200,000+ documents on the platform and operates under LGPD-compliant data handling with explicit contractual prohibitions on training third-party models on customer data.

Judex competitors and assessment
Company assessmentEmerging players
- Lawyaw: Document automation platform for lawyers that turns prior legal documents into reusable templates with auto-fill from case data. Comparable to Judex's Editor de peças for AI-assisted legal document drafting with reusable templates.
