EU AI Act Ready — Aug 2026
Your AI that learns you, not from you.
Self-hosted AI assistant that adapts to how you think, work, and communicate — while keeping every byte on your own servers.
By invitation only. We review every request personally.
KAI is a self-hosted, privacy-first AI assistant built by KAUFAST in Barcelona. It runs on your own server, keeps all data in an AES-256 encrypted database under your control, and uses smart privacy routing to automatically process sensitive queries (health, legal, financial) on-device while routing general queries to cloud AI for speed. KAI includes 13 productivity panels — tasks, reminders, notes, projects, meetings, email, calendar, habits, mood tracking, and more — in a single interface. It is GDPR compliant by architecture and designed for EU AI Act compliance (effective August 2026). Available on iOS, Android, macOS, and Linux.
Privacy Router
Sensitive data never leaves. Automatically.
Every message is scanned for sensitive content — health records, legal terms, financial data. Sensitive queries route to local inference. No toggle. No mode. It just works.
Sensitive query detected

How It Works
Deploy in minutes. Own your data forever.
KAI runs on any machine with Node.js. No GPU required. Under 50MB total.
Deploy to your server
Clone the repo, set environment variables, run node server/index.js. Works on a €7/month VPS, Raspberry Pi, or enterprise infrastructure.
Connect your services
Add Gmail, Proton Mail, Google Calendar, and your AI providers. KAI supports multi-provider fallback chains — fast US cloud, EU-native GDPR cloud, or fully local inference.
Use across all devices
Install the native app on iOS, Android, or macOS. Or use the PWA from any browser. Same encrypted data, same interface, same privacy guarantees.
KAI adapts to you
The more you use KAI, the more it learns your communication style, expertise, and preferences — stored locally in a database only you control.
Adaptive Persona
KAI Remembers. KAI Adapts. KAI Is Yours.
Every conversation teaches KAI more about how you work. Your tone, expertise, clients, preferences — stored locally in a database you fully control.
Learns from every conversation
Vocabulary, preferences, recurring topics. After a week it feels like talking to a colleague who knows your business.
Per-conversation personas
Switch to “legal advisor” for contracts or “medical assistant” for patient processing. Each carries its own expertise.
Memory you control
View, edit, or delete anything KAI remembers. Export as JSON. Wipe with one click. Your hardware, your rules.
Client-specific knowledge
KAI remembers client names, case details, treatment protocols. Context that makes every interaction sharper.
Who It's For
Built for people who can't afford a data breach.
Designed for professionals where confidentiality isn't a preference — it's a legal requirement.
Healthcare
Patient summaries, treatment plans, referral letters. Sensitive data routes to local AI automatically — real isolation, not compliance theatre.
Legal
Contract review, case research, NDA drafting. Client names never reach the cloud. Ghost mode for privileged conversations.
Finance
Portfolio analysis, tax strategy, audit prep. AES-256 encrypted database with air-gap mode for fiduciary conversations.
Consulting
Client briefs, strategic notes, project personas. KAI adapts per engagement — different context, different expertise, one tool.
Executive
Board prep, investor updates, personnel decisions. Duress PIN for forced-unlock scenarios. Remote wipe for lost devices.
Privacy-First Individuals
Journaling, health tracking, personal planning. Your thoughts stay yours. No training data. No profiling. Full delete anytime.
Everything It Does
Built Lean. Ships Complete.
Under 50MB. Deploys with one command. No GPU required — plug in your model provider and go.
Why It Matters
The cost of ignoring data privacy.
AI tools that store your data on third-party servers expose you to breach risk, regulatory fines, and loss of client trust. The numbers tell the story.
KAI eliminates these risks by keeping all data on your own server. No third-party storage means no third-party breach. GDPR compliance comes from architecture, not policy documents.
Efficiency & Sustainability
Local AI That Scales. Responsibly.
KAI's local processing engine runs on standard hardware — no GPU clusters, no cloud round-trips, no wasted energy. Built from day one to adopt compression advances as they ship.
Sensitive queries are processed entirely on your hardware. No data ever leaves your network. Runs on 8GB RAM — a €7/month VPS or a Raspberry Pi.
Q2 2026: KV cache compression (peer-reviewed, Google Research) will extend local context to 100K+ tokens on the same hardware. No code changes — ships via the local inference runtime automatically.
Local inference eliminates data centre round-trips. Quantised engines use a fraction of the energy of GPU clusters. KAI is designed to run efficiently on low-power hardware — privacy and sustainability, aligned.
Efficiency Across the Market
| KAI (Local) | Cloud AI | |
|---|---|---|
| Data leaves your network | Never (local mode) | Every query |
| Hardware required | 8GB RAM, no GPU | Internet + subscription |
| Inference cost | €0 (your hardware) | $20–100+/mo |
| Context window (current) | 32K tokens | 128K tokens |
| Context window (Q2 2026) | 100K+ tokens | 128K tokens |
| Energy per query | ~5W (local CPU) | 300W+ (GPU cluster) |
| Privacy guarantee | Cryptographic | Policy-based |
KAI is built from the start to adopt compression advances as they ship. When Google’s TurboQuant lands in the open-source ecosystem (Q2 2026), KAI’s local mode gets 6x more context — no update, no migration, no code change.
