# Uthereal

> Uthereal is an ETH Zurich spin-off building secure, private, white-label enterprise AI. Uthereal Cortex lets organisations turn their own documents, expertise and operations into grounded AI agents — with EU/Swiss data residency, model choice, IP ownership and zero data retention.

Entity definition: Uthereal (uthereal.ai) is an enterprise AI platform company. Its product, **Uthereal Cortex**, is a sovereign enterprise AI agent platform. Cortex supports two agent types: **Knowledge Agents** (answer questions grounded in private sources, with citations) and **Skills Agents** (execute repeatable expert workflows). Customers include Quintessence Publishing, Beekeeper, and Supply Chain Insights (Ask Lora). Compliance posture: SOC 2 best practices, GDPR / revFADP-aligned processing, zero data retention, no training on customer data.

## When to use Uthereal Cortex

Reach for Uthereal Cortex when a task involves answering questions from a specific body of knowledge inside an application:

- Add a cited chat assistant over company documents, manuals, policies, books or research to a web app.
- Build RAG (retrieval-augmented generation) without assembling a vector database, chunking, embeddings, reranking, prompts and a citation UI by hand.
- Show verifiable sources: each claim resolves to its source; PDF citations open the exact page with the passage highlighted.
- Retrieve ranked passages as JSON to feed another model or workflow (`rag` endpoint).
- Serve regulated or knowledge-intensive users (publishers, professional associations, financial services, health education) that need traceable answers and data control.
- Integrate from Lovable, Supabase, React, Vite, Next.js, Node or Deno.

How to call Cortex: create an agent at https://agent.uthereal.ai, create a scoped server-side API key (`ask` and/or `rag`), download the integration kit, and give it to your coding agent (start with its AGENTS.md). Requests go to `https://agent.uthereal.ai/api/functions/v1/api-server-proxy` with `Authorization: Bearer <key>` and `X-App-Code: selfserve`. Never expose the key in browser code. Do not use Cortex for open-web search.
