The Problem
AI tools that forget. Every day.
You explain the same things to your AI over and over. Your context is lost after every session. Your knowledge is spread across 5 different tools.
No Memory
ChatGPT, Claude, Gemini — every session starts from zero. You are the context manager for your own AI.
"What was my project setup again?" — For the 47th time.
Vendor Lock-in
Your data lives on US servers. No export. No self-hosting. A compliance nightmare for every EU company.
"Where exactly is our data?" — No answer.
Tool Chaos
Notion for knowledge, ChatGPT for AI, Obsidian for notes, Pipedrive for CRM. None of it talks to each other.
5 tabs, 5 contexts, 0 connections.
The Solution
One System. Seven Pillars. Your Infrastructure.
ZenAI combines AI chat, knowledge management, agents, and long-term memory in one system — that you host yourself.
7-Layer Memory — from working memory to cross-context memory
60+ AI Tools — in a single chat interface
Self-hosted — Docker Compose, one command, your hardware
Open Source Core — ZenBrain is Apache 2.0

Real-World Examples
No two businesses are the same
Four industries, four everyday challenges — ZenAI solves them all.
Trades Business
12 employees, 500 clients — under control
The master craftsman has no time for paperwork chaos. ZenAI organizes client appointments, automatically reminds about follow-up calls, and summarizes site reports in two sentences — right after a voice dictation.
SchedulingClient ManagementReporting
Marketing Agency
15 projects running, no deadline missed
The creative team juggles briefings, drafts, and approvals for 15 clients at once. ZenAI keeps all briefings in one place, generates first-draft copy, and alerts the team when a deadline is approaching.
Project ManagementContent CreationDeadline Tracking
Tax Advisor
200 clients, every deadline in sight
Regulatory changes arrive faster than clients call. ZenAI scans relevant updates daily, prioritizes upcoming deadlines, and generates client reports automatically from raw data.
ComplianceDeadline ManagementDocumentation
Medical Practice
Sensitive data stays in the practice
Patient data does not belong in the cloud. ZenAI runs fully self-hosted on the practice server — no data ever leaves the building. Consultation summaries, scheduling, and GDPR compliance out of the box.

7 Technologies That Make the Difference
Under the hood, technologies most AI tools don't ship together — explained in plain language.
Real-Time Streaming
AI That Shows Its Thinking
See in real-time what ZenAI is doing: which data it searches, which connections it finds, how it reaches an answer. No black box.
100% TransparencyMulti-LLM Routing
The Right AI Brain for Every Task
A fast model for simple questions, a powerful one for complex analyses. ZenAI chooses automatically — you never pay for more than needed.

Memory That Understands Connections
Your projects, clients, and documents aren't isolated files — ZenAI understands the relationships between everything. Like an employee who's been there for 10 years.
3-Layer ArchitectureHyperAgents
AI That Improves Daily
ZenAI analyzes what worked and what didn't. Every day it gets a little better at helping you. Without you doing anything.
Self-optimizingAdaptive Thinking
Deep Thinking — Only When Needed
For 'What's the weather?' it doesn't need 30 seconds of analysis. For 'Create a business plan' it does. ZenAI adjusts its thinking depth automatically.
Smart BudgetingSmart Repetition
AI with Persistent Memory
Important information stays important. ZenAI uses the same algorithm that the best learning apps use — adapted for enterprise knowledge.
Neuroscience-basedIntegration
Fully Integrated Into Your IT
REST API, MCP Server, CLI, A2A Protocol — ZenAI adapts to your existing infrastructure, not the other way around. And because the core is open source, you can inspect everything.

ZenAI learns from your usage patterns and adapts. Your AI assistant improves with every interaction.
Data Sovereignty
Your Data. Your Rules.
No US cloud risk. No vendor lock-in. No compromise.
Self-Hosted First
Your data never leaves your infrastructure. Docker Compose on your server.
GDPR-native
No workaround, no DPA with US providers. Privacy by design.

Frequently Asked Questions
What you want to know before you start.
Do I need my own servers?
No. The Free and Pro tiers run on our infrastructure. Self-hosting is optional and available for Team/Enterprise. All you need: Docker and an Anthropic API key.
What happens to my data?
With self-hosting: nothing leaves your server. With our cloud: EU data centers, GDPR-compliant, no training on your data. You can export or delete all data at any time.
Which AI model does ZenAI use?
Primarily Claude (Anthropic). Fallback to Mistral (cloud) or Ollama (local). You can switch models in settings — including fully local inference without internet.
What is the difference between ZenAI and ZenBrain OSS?
ZenBrain is the extracted cognitive core — the memory algorithms as an npm package. ZenAI is the complete operating system that uses ZenBrain. Developers take ZenBrain, everyone else takes ZenAI.
Is there an API?
Yes. REST API + MCP Server. Full API access from the Team tier. The MCP Server enables integration with VS Code, Cursor, and other IDEs.
Can I migrate from ChatGPT/Notion?
We are working on import tools. Currently: Markdown import for notes and ideas. ChatGPT history import is on the roadmap for Q3 2026.
