Auditable, secure, and sovereign search engine.
Lexiane is an AI-augmented search engine (RAG), certifiable and auditable by your experts. Your teams leverage your confidential documents directly on your infrastructure, with full traceability on every operation.
Discover the platform
AI evolves. Your foundation stays put.
European companies need a reliable solution — one that is compliant with the strictest regulations. A transparent and certifiable solution for specific environments, guaranteeing total data security.
- Data security by design
- Regulatory and certification compliance
- Traceability and auditability on every operation
- Scalable and robust architecture
- Full processing transparency
How is Lexiane different from existing solutions?
Lexiane is a RAG natively designed for the most demanding constraints. Its architecture radically separates the certified core from the surrounding tools. Security, auditability, and compliance are not added features — they are the very foundations of Lexiane.
Modular architecture and predictable code
Modular by design
Replace any component — vector store, LLM engine, embedding model, reranker — without rewriting or touching a single line of code in your pipeline. Over 25 extensible port interfaces.
Deterministic execution
Our code is compiled, with no runtime overhead. It delivers predictable, auditable performance for the most critical environments.
Three deployment modes to suit any environment
100% air-gapped execution with local models, cloud connection via OpenAI or Anthropic, or hybrid mode. Same engine, same API, three strategies tailored to your constraints.
Ideal design for regulated industries.
Compliant from the ground up with European requirements — EU AI Act, GDPR, NIS2, defense directive. Built for healthcare, defense, government, and sectors subject to IEC 62304 and ISO 26262 standards.
Sourced and verifiable answers, to guarantee trust.
An application cannot be adopted without reliable and precise answers. We integrate best practices such as relevance filtering, source citations, and confidence scoring — ensuring your AI abstains when evidence is insufficient, rather than fabricating answers.
Banking
Leverage your regulatory and financial documents with AI, in compliance with ECB and ACPR requirements.
Government
Give your agents intelligent access to public documents, in compliance with GDPR and SecNumCloud frameworks.
Industries
Query your technical documentation, quality procedures, and audit reports without exposing your intellectual property.
Defense
Document intelligence in classified environments. Air-gapped deployment, no outbound connections, full traceability.
Healthcare
AI-augmented search on clinical records and medical literature, compliant with IEC 62304 and the European Medical Devices Regulation.
Enterprise
The power of an LLM applied to your internal documentation — intranet, HR procedures, product knowledge base, project archives. Where you decide.
End-to-end processing, without compromise.
From document ingestion to AI-powered answers, every step is designed for security, compliance, and transparency.
1,254 automated tests. 27 independent modules. 25 abstraction interfaces. 0 proprietary dependencies in the certified core.
- 1
Document ingestion
Batch or single-file processing. PDF, Excel, PPTX, HTML, Markdown with automatic metadata extraction.
- 2
Personal data protection
Automatic detection and masking of sensitive data — names, phone numbers, bank accounts, emails — before any AI processing.
- 3
Data chunking
Recursive, hierarchical chunking with parent-child relationships for precise, context-aware retrieval.
- 4
Semantic enrichment
Vector indexing and data contextualization for search that understands meaning, not just keywords.
- 5
Knowledge graph extraction
Automatic entity and relationship extraction for complex queries across your entire document corpus.
- 6
SHA-256 cryptographic trail
Every pipeline operation is cryptographically signed. Fully exportable for compliance reviews.
- 7
Full auditability
Every ingestion, query, and AI response is logged and traceable. Ready for internal and regulatory audits.
- 8
Ferrocene compiler certification
Core compatible with the Ferrocene certified Rust compiler, qualified for safety-critical environments under IEC 62304 and ISO 26262 standards.
