Lexiius is a document anonymization platform built for professionals. Its goal is to replace real client data with variables before contracts, case files, tax materials, HR documents, and similar records are sent to ChatGPT, Claude, Gemini, or other LLMs. It is not a general-purpose AI Q&A tool, but a privacy protection layer within an AI workflow.
The platform uses an NLP engine to detect sensitive information such as names, DNI, CUIT, bank accounts, addresses, phone numbers, email addresses, and monetary amounts, with document-pattern support tailored to legal and accounting materials across 13 Latin American countries. After uploading PDF, DOCX, TXT, and other files, users can review the system’s detections before confirmation, remove false positives, or manually add missed items, then generate an anonymized document. The output preserves the main meaning of the document while replacing only sensitive fields with variables such as {{NOMBRE_1}} and {{DNI_1}}, making it easy for external AI tools to continue reading and analyzing the content.
Lexiius supports a read-only REST API and the MCP protocol, and can connect to Claude Desktop, ChatGPT Actions, Gemini, or any tool capable of reading a REST API. Its endpoints only allow GET requests, meaning AI can list and read anonymized documents but cannot create, modify, or delete them. On the security side, original files are deleted after anonymization is confirmed, while mappings between real values and variables are stored with AES-256 encryption. Communications use HTTPS, tokens can be scope-limited and revoked immediately, and access records are written to audit logs. The site also discloses infrastructure components such as Cloudflare R2, PostgreSQL, Microsoft Presidio, and FastAPI.
The free plan is permanently free and does not require a credit card. It includes 10 documents per month, 100MB of storage, and 1 MCP token. The Professional plan is listed at $29/month, and the Team plan at $19/user/month, but both are currently marked as “coming soon.” Lexiius is especially suited to lawyers, accountants, tax advisors, HR teams, and real estate agencies in Latin America that need to redact client information before submitting materials to AI tools.
Its strengths are a focused use case, a low-friction free tier, review support, a read-only API, and a clear privacy-oriented design. The limitations are also clear: automatic detection is not guaranteed to be 100% accurate, and final review remains the user’s responsibility; the service is still at an early stage and does not guarantee 100% availability; Chinese document support is not specified, and the site’s main languages are Spanish, Portuguese, and English. Access from mainland China and supported payment methods are not disclosed in the main content, so they should be treated as “unknown.” For China-specific compliance scenarios, local DLP tools, data masking systems, or cloud provider privacy-protection services may be worth evaluating as alternatives.
