Sovereign AI · Built in the EU

Secure AI for your
confidential data

Chat with frontier AI, build agents, and orchestrate multi-agent workflows — with your data encrypted, kept in the EU, and never handed to outside vendors.

EU-ONLY MODELS AES-256-GCM AT REST ZERO DATA RETENTION NO EXTERNAL VENDORS

Zero Data Retention is disclosed per model and contracted with providers where supported.

One workspace

Three surfaces, one secure home

Everyday chat, reusable agents, and visual workflows — all on the same encrypted, EU-first foundation.

01 — CHAT

Secure Chat

A fast, multi-model chat for everyday work. Attach a document or ground it on your knowledge — every message encrypted at rest.

02 — AGENTS

Agents

Reusable assistants you configure once — model, instructions, skills, tools and knowledge — then use anywhere, with versions you can roll back.

03 — WORKFLOWS

Workflows

Connect agents, tools and steps into repeatable processes on a visual canvas — up to a multi-agent team led by a coordinator.

Secure Chat

Frontier models, on your terms

Secure Chat is the home screen: a fast, multi-model chat where everything you send and receive is encrypted at rest and processed on EU (or self-hosted) models. Every reply shows the model that answered.

  • Attach files or ground answers on your knowledge bases
  • Auto-routing picks a capable model, or choose one yourself
  • Group chats into projects to keep work separate

Agents

Configure once, use everywhere

An agent bundles a model, a system prompt, optional skills, the tools it may call, and a knowledge base. Deploy it, then use it in chat or drop it into a workflow — each save is captured as a version you can roll back to.

  • Built-in tools run in niil's own runtime — no third-party services
  • Draft → configure → deploy → use, with a clear lifecycle
  • Personal or shared across your whole organization

Workflows

Orchestrate agents on a canvas

Connect agents, tools and steps into a repeatable process — from a simple "summarize this and email it" to a multi-agent team coordinated by a lead agent. Trigger on a message, a schedule, or a webhook.

  • Typed ports and edges — inputs, agents, tools, outputs
  • Delegation and context broadcast between sub-agents
  • Import and export as YAML, save shapes as templates

Knowledge bases

Ground answers in your own material

Upload your documents once, then ground many chats and agents on them with retrieval. Personal or organization-wide, indexed for search, and encrypted at rest like everything else.

  • Supports .md, .txt, .csv, .json, .pdf, .docx, .xlsx, .pptx
  • Self-hosted / EU embeddings only — residency preserved
  • Portable open-knowledge import and export

Usage & governance

See every run, every cost

Tracing shows what your agents and workflows actually did — every run with its status, tokens, cost and full step tree. Set per-person and per-organization budgets, and keep an immutable audit trail behind it all.

  • Transparent per-person and per-org spend, in EUR
  • Budgets, warnings and DLP scanning
  • GDPR data export and erasure, on request

Trust model

Sovereign by design, not by promise

niil is built so your data stays protected and under your control. Here is what that means, in plain terms.

EU sovereignty

EU-processed by default

Every organization is restricted to EU-processed (or self-hosted) models. Inference is region-pinned to EU endpoints — you choose the processor and see it in the picker.

Encryption

Encrypted end to end at rest

Chat content, documents and connector credentials are encrypted with AES-256-GCM. Each conversation has its own key, so deletion is a true crypto-shred.

Authentication

Modern auth & MFA

Passwords, email one-time-code MFA, passkeys (WebAuthn / FIDO2) and social sign-in — configurable per organization.

Data protection

GDPR, built in

Data export and erasure, DLP scanning, an immutable audit trail, and strict tenant isolation between organizations.

Retention

Zero Data Retention

Retention and the processor are disclosed per model, and ZDR is contracted with providers where they support it.

Independence

No external vendors

A self-hosted runtime with built-in tools. No third-party analytics or telemetry — EU-hosted Stripe only if you enable billing.

Secure by default

The defaults are the safe ones. An organization can relax a policy deliberately, but nothing sensitive is opt-in.
