Your Data.
Your AI.
Your Rules.
Ontheia is the self-hosted AI agent platform.
AI without control is a liability
Data leaking through the back door
Every request to a cloud AI sends your data to foreign servers — uncontrolled, opaque.
Vendor lock-in
One provider change, one price hike, one updated ToS — and your AI stack collapses.
Compliance risk
Personal data in US cloud services is legally precarious in the EU. That costs nerves — and potentially money.
What Ontheia is
Self-hosted
Runs on your own infrastructure. Docker-based, easy to deploy.
Multi-provider
Claude, ChatGPT, Grok, Gemini, Ollama — you choose the model. No lock-in.
Multi-User
Role-based access control, teams, and projects — Ontheia is built for organizations from the ground up.
MCP-Native
Built on the Model Context Protocol as an open standard. Connect agents to any external tool — no proprietary integrations required.
Skills
Package knowledge and workflows into reusable modules — instructions, scripts, and references. Define once, use from any agent.
Cron Automation
One-time or recurring jobs — set up via form or directly in chat: "Every morning at 9:00, summarize the news and send it to my inbox."
Workflow Engine
Visual automation pipelines. Complex agent logic without code.
Long-term Memory
Built-in RAG with pgvector. Your agents remember and access your knowledge base.
Agent-to-Agent
Agents communicate directly with each other. Complex tasks can be split and coordinated between agents.
Ontheia in Action
The WebUI runs in your browser — on your servers.

Your data never leaves your infrastructure.
Who uses Ontheia
Sovereignty — for your industry, your workflows, your rules.
Protecting professional secrecy
Doctors document findings, search medical literature via RAG, and prepare correspondence. Lawyers review contracts and research case law. Patient and client data never leaves your own infrastructure.
Compliance without compromise
Automatically analyze loan documents, generate regulatory reports, and monitor transactions for anomalies. Banks are subject to strict financial regulation and banking secrecy — customer data in US cloud is not an option.
Citizen services on your own servers
Automatically classify and respond to citizen inquiries, process forms, maintain internal knowledge bases. Faster citizen service, less burden on staff — with full sovereignty over all administrative data.
Intelligent production monitoring
Analyze machine and sensor data in real time, detect anomalies, predict maintenance needs. Produce more efficiently, reduce downtime. The knowledge of your plant works for you.
Structured access to project knowledge
Automatically maintain planning documents, search standards and regulations via RAG, generate technical reports. Every project enriches the knowledge base. Over time, accumulated know-how works for every new assignment.
Automating day-to-day operations
Capture and track orders, prepare supplier requests, automatically inform customers about delivery dates, create correspondence and quotes. More time for the actual work.
Your Rules. Per Agent.
Ontheia runs on your servers — files, agent knowledge, and conversations stay in-house. You decide per agent which model it may use: sensitive customer and personnel data stays with local models, routine tasks may go to the cloud. The architecture enforces your rules, not just your policy — and in teams, everyone sees only their own data. GDPR compliance you can verify.
