An AI studio to transform, your sources into actionable knowledge
MaTHEO brings together in one place natural-language document search, management of a private knowledge base (PDF, Word, audio, video, web…) organized into thematic libraries, and collaborative sharing across organizations. Multi-AI (GPT, Claude, Gemini, Mistral, DeepSeek), multilingual (13 languages), with precise citations for every answer. Domain-specific spaces are available, starting with 'Evangelical Theology' (public-domain Bibles, Church Fathers, Reformation, Calvin, major evangelical libraries) and a 'matheo Teachings' system to capitalize knowledge between peers.
Search · Manage · Share — without ever losing control of your sources.
