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.

Nexoria

Nexoria is a work platform for businesses. Its core combines knowledge storage, Nexoria Drive, enterprise search (document search) and the Nex AI assistant. Nexoria Office includes Doc, Calc and Slides. Documents in Nex, workspaces and permissions, OCR, transcription, tasks, chatbots and automations complement the platform. Nexoria Mail, Nexoria Meet and VoiceBot are optional add-ons. VoiceBot requires a Nexoria subscription. Connections are set up on request, depending on the environment and permissions; additional target systems are assessed for the specific project. Files and the core knowledge index are stored on servers in Germany. Answer generation uses the Mistral AI API. External AI and other enabled services have separate data flows; processing locations, terms and settings need to be checked for each service.

OKA

OKA is a front-desk assistant for small offices. Staff ask a question in plain words, and OKA answers only from the office's own written procedures. Each answer quotes the passage it used and names the procedure, so staff can check it. When the procedures don't cover a question, OKA says so and points staff to the right person instead of guessing. It is built for offices where the same questions come up every day: law firms, veterinary clinics, property managers, insurance agencies and other small offices. Offices can start with a free week: send up to 10 procedures, and Forge sets up a private assistant with staff logins within one business day. No meeting and no credit card. OKA Anywhere, the self-serve option, brings an office's procedures into Claude or ChatGPT through a custom connector. Offices send written procedures only, never client or patient records. Questions and answers are never stored on Forge's servers, and documents are never used to train AI models.
