narratheque.io

narratheque.io is a multi-LLM SaaS AI platform for creating, managing and certifying "sovereign knowledge bases" in the form of private RAGs. Knowledge bases are generated from the import of data in the form of integrated modules that are extremely simple to use (import, .pdf, videos, youtube, scrap url, etc...). The platform is responsible for analyzing and vectorizing data automatically on servers hosted in France. Each generated base can be queried by any LLM (depending on the desired level of permeability and fineness). The database can also be searched outside the platform through Chatbots that can be deployed in a few clicks (WordPress module, html embed, or direct link). These bases can be certified by owners who wish to make their documentary assets accessible.
