What Judex does

Judex (legal entity JUDEX LTDA., CNPJ 66.745.737/0001-41) is a Brazilian legal technology company operating an AI-powered SaaS platform exclusively for Brazilian lawyers and law firms. The platform unifies four interconnected products: an AI document editor (Editor de peças) with 80+ specialized templates, an AI legal research assistant (Assistente Jurídico) that returns jurisprudence sourced from real Brazilian court decisions (STJ, STF, TRTs, TJs) with verifiable citations, an automated deadline and publication monitoring module (Prazos e publicações) driven by native OAB integration, and a case management system (Processos) with automatic process import and real-time updates from federal, labor, and state courts including TRFs, TRTs, TJSP, TJRJ, TJMG, TJRS, PJe, and e-SAJ. Coverage spans 24+ Brazilian legal practice areas including Civil, Labor, Criminal, Tax, Family, Social Security, Corporate, Real Estate, Consumer, and Corporate/Societário law, and the platform is LGPD-compliant with workspace-level data isolation.

The underlying technology stack combines multiple third-party generative AI providers (OpenAI, Anthropic Claude, Google Gemini) with domain-specific prompt orchestration, an optional Claude/MCP integration that lets clients connect external AI assistants to their workspace, and infrastructure partners including Supabase (auth/database on AWS), Stripe (billing), PostHog (analytics), Sentry (error monitoring), and Resend (transactional email). Document drafting, jurisprudence retrieval, deadline calculation, and process monitoring are packaged into a workflow that Brazilian advocates can adopt without learning new software, with output exported as Word documents ready for court filing.

The business model is a subscription SaaS with usage-based AI credit consumption: Profissional at R$99/month targeting solo lawyers (1 user, 100 processes), Escritório at R$579/month for small teams (up to 10 members, 1,500 processes), and Escritório Plus at custom multi-year pricing for large firms with unlimited capacity, weekly meetings, and custom features. A 7-day free trial without credit card requirement anchors a product-led growth motion for the long tail of individual advocates, while inside-sales demos handle enterprise prospects. The platform reports 12,000+ active lawyers and 200,000+ documents generated, with 40% efficiency gains cited by users and 99.9% platform uptime. Geographic scope is exclusively domestic (Brazil), and no external funding rounds, acquisitions, or management team are disclosed in the available source material.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Projuris: Brazilian legal practice management platform offering case management, deadline monitoring, document automation, and team workflows for law firms. Direct competitor to Judex in the Brazilian legaltech market with similar SMB and firm customer focus.
• Astrea: Brazilian legaltech platform providing case management, document automation, and legal workflow tools for lawyers and law firms. Competes with Judex on Brazilian legal specialization and SMB-focused subscription pricing.
• Legalbox: Brazilian legaltech platform serving lawyers and law firms with document automation, case management, and workflow tools. Direct competitor to Judex targeting the same solo and small-firm Brazilian legal market.

Broad incumbents

• Softplan / SAJ: Established Brazilian legal software provider with SAJ (Sistema de Automação Judicial) and broader justice-system products. Larger incumbent serving courts and law firms with broader portfolio beyond legal AI specialization.
• Harvey: Well-funded global legal AI platform serving law firms and enterprises with domain-specialized generative AI. While focused on English-speaking markets, Harvey represents the strategic competitive threat Judex will face if/when global legal AI vendors localize for Brazil.
• Thomson Reuters CoCounsel: Enterprise legal AI suite from Thomson Reuters combining Westlaw, Practical Law, and CoCounsel AI capabilities. Broad incumbent with overlapping document automation and legal research functionality, though not Brazil-specialized.
• LexisNexis Protege: LexisNexis AI legal assistant offering AI-powered legal research, drafting, and analysis integrated with Lexis legal content. Established incumbent with global footprint but limited Brazilian legal specialization compared to Judex.

Emerging players

• Spellbook: AI-powered legal drafting assistant for lawyers using generative AI for contract review and document generation. Comparable in product category (legal AI drafting) but focused on common-law jurisdictions rather than Brazilian civil law practice.

Others

• Jusbrasil: Brazil's largest legal research and jurisprudence platform serving lawyers, law students, and the public. Adjacent ecosystem player providing legal content that could be integrated into Judex or compete at the research layer rather than the full practice platform.
• Escavador: Brazilian legal data and background-check platform aggregating court records, processes, and jurisprudence. Complementary data provider whose court data infrastructure overlaps with Judex's process monitoring capabilities.
