Semios Ai

What Semios Ai does

Semios AI is a privately held French software company headquartered in Toulouse that builds an AI-powered semantic analysis platform for technical documentation, with a particular focus on requirements engineering in safety-critical industries. The company originated in 2010 from a research collaboration with IRIT (Institut de Recherche en Informatique de Toulouse) and CNAM (Conservatoire National des Arts et Métiers) on Automatic Natural Language Processing (TALN), and has since evolved the product through early "Lelie" prototypes, Word/Doors add-ons, and the current Semios platform (rebranded to Semios.ai in 2022). Its core technology combines machine learning, linguistic algorithms, and a rule-based library of more than 80 detection rules derived from international systems-engineering standards (IEEE 830, ISO 29148, INCOSE, IREB, ARP 4754, ASD-STE 100, DO-178B/C, IEC 61508, ISO 26262), delivering explainable and reproducible analysis rather than purely statistical LLM outputs.

The platform is organized around six modules: Sémantique (diagnostics of ambiguities and inaccuracies), Reformulation (AI-assisted rewriting), Génération (automated child-requirement creation), Cohérence (consistency between linked requirements), Complétude (coverage gap detection), and Extraction (extraction of requirements from standards and reference documents). Native integrations with Siemens Polarion (since 2021, part of the Siemens Xcelerator portfolio), IBM Doors/Doors NG, Jama Connect, Visure, and Microsoft Word/Excel/Office 365 allow the engine to be embedded directly inside customers' ALM and productivity workflows. Generative AI capabilities, added in October 2023, can run on client-chosen LLMs including internet-isolated models such as Llama 2 for data confidentiality. A white-label/OEM API is also available, demonstrated with EDF.

Semios targets enterprise customers in aerospace and defense (CNES since 2017, Safran, Thales), energy and nuclear (EDF since 2023), railway and transportation (SNCF since 2021, Systra), automotive (Continental), and pharmaceuticals (Merck). The commercial model is enterprise-led, combining annual subscription or perpetual license with annual maintenance, an on-demand monthly document-analysis tier, and paid Proof-of-Concept (POC) evaluation services run over roughly three months with Semios experts on-site. Distribution combines direct enterprise sales with technology integration partners (Siemens, IBM, Jama, Visure, 3DS Outscale, hyperscalers) and a network of implementation SIs (LGM, Axone, Compliance, Emenda, isit, webinage), with primary commercial distribution handled by Kadlog, a consulting firm led by Semios Commercial Director Didier Mascarelli. Managing Director Thomas van de Velde oversees the company alongside Mascarelli.

Core offering

Semios AI is a French AI/NLP software company that provides automated semantic analysis of technical documentation for enterprises in safety-critical industries. The platform uses artificial intelligence and natural language processing to evaluate the quality, consistency, completeness, and traceability of requirements and specification documents, helping engineering teams reduce manual review effort and improve documentation rigor. Founded in 2010 through a research collaboration with IRIT (Institut de Recherche en Informatique de Toulouse), the company sells its software to organizations in aerospace, defense, nuclear energy, railway, and automotive sectors.

Product overview

Semios is a unified AI platform for semantic analysis of technical documentation with a modular architecture comprising six core analysis modules: Semantics (diagnostic), Reformulation (AI-powered writing improvement), Generation (automated requirements creation), Consistency (cross-requirement analysis), Completeness (coverage assessment), and Extraction (standards analysis). These modules integrate natively with popular ALM platforms (Siemens Polarion, IBM Doors/Doors NG, Jama) and productivity tools (Microsoft Word, Excel, Office 365). The platform is available as annual subscription, perpetual license, or on-demand document analysis, with optional white-label API deployment for enterprise customers.
