Get Early Access

Intelligence that lives where you do

KAI is short for Krætus AI. KAI is a personal AI assistant designed for families. It runs on hardware in your home, keeps your data completely private, and gets smarter the longer you use it.

Local-First

Your data never leaves your home. Every conversation, every memory, every interaction stays on your hardware. No cloud servers. No data harvesting. Ever.

Family Safe

A constitutional safety framework protects every family member. Child safety isn't a setting you toggle on. It's hardcoded into the system and cannot be overridden.

Truly Yours

Buy once, own forever. No monthly subscriptions. No premium tiers. Your investment in KAI is yours to keep, just like the hardware it runs on.

Not another cloud assistant

Today's AI assistants send your voice, your questions, and your habits to corporate servers. KAI does the opposite.

Complete Privacy

Zero cloud AI dependencies. Your conversations never leave your network. No recordings sent to servers. No data used to train someone else's model.

Constitutional Safety

Safety guardrails are compiled into the system at the code level. They can't be bypassed by clever prompts, disabled by settings, or weakened by updates.

Persistent Memory

KAI remembers your family. Preferences, routines, important dates, inside jokes. It learns over time and keeps memories private to each family member.

Voice-First

Natural wake word activation with real-time speech recognition and synthesis. Talk to KAI like you'd talk to a person, not a machine.

Personality System

Customize how KAI sounds and feels. Choose from Ktrætus or community-built personalities. Think of personalities as a costum your AI wears, and you can change the personality at any time. The soul stays constant; the style is yours to shape.

Home Automation

Control your smart home with natural language. Lights, scenes, routines. No separate app. Just ask KAI and it happens.

Your family's privacy is not negotiable

  • Constitutional Child Protection

    Safety rules are hardcoded in compiled code. They cannot be overridden by anyone, including the system itself. Children are protected by design, not by policy.

  • Multi-User Memory

    Each family member has their own memory space. Kids can't access adult conversations. Personal memories stay personal. Shared memories bring the family together.

  • Age-Appropriate Content

    Automatic content gating ensures every interaction is appropriate for the person speaking. No parental controls to configure. It just works.

  • Data Sovereignty

    Your conversations, memories, and family data never touch a cloud server. Everything stays on hardware you own, in your home, under your control.

Protected

Buy once. Own forever.

No monthly fees. No premium tiers. No lock-in. KAI runs on your hardware, uses your electricity, and belongs to you.
