Overview
Why Ontheia?
Every time you send a company document to a cloud AI, your data leaves your building. Ontheia keeps AI powerful — and keeps your data yours.
- GDPR-compliant by architecture — data never leaves your servers
- Vendor-agnostic — Claude, ChatGPT, Gemini, Grok, Ollama, or any OpenAI-compatible model
- MCP-native — connect agents to any external tool or service via open standard
- Multi-user — role-based access control, Row Level Security enforced at the database level
- Chain Engine — visual workflow automation, no code required
- Long-term Memory — built-in RAG with pgvector, isolated per user and namespace
- Agent-to-Agent — complex tasks coordinated across specialized sub-agents
- Cron Automation — schedule agent runs and chain executions on a time-based trigger
