Your AI.
Your Mac.
Nothing leaves.

M1K3 is a native AI companion that runs entirely on your Mac. Local models, live voice, a knowledge graph that remembers everything — and a network cable it never asks for.

Call memory

Consent-gated call recording with on-device transcription, speaker-grouped summaries, and encrypted persistence. Your calls become searchable knowledge.

An agent that does

A built-in ReAct agent with real tools — web search, page reading, your knowledge base — behind a privacy toggle. Web off means web off.

Mac-native,
to the metal.

Not an Electron wrapper. Not a webview. A SwiftUI app with Liquid Glass, RealityKit avatars, and Metal-accelerated inference — built for macOS Tahoe and nothing else.

// questions

Straight answers.

Does M1K3 send my data to a server?

No. M1K3 runs entirely on your Mac — inference, voice, embeddings, and storage are all on-device. Zero bytes of your conversations, documents, or calls go to any server. The optional web-search tool is off by default and clearly toggled.

What AI models does it run?

Three brains, all local: Apple Foundation Models for instant answers, Qwen 3 4B, and Gemma 4 12B for deep reasoning — via MLX-Swift on Apple Silicon. Switch in Settings any time.

Which Macs are supported?

Apple Silicon Macs on macOS 26 Tahoe. M1K3 is a native SwiftUI app with Metal-accelerated inference — not an Electron wrapper.

How is it different from Ollama or ChatGPT?

Ollama is a local model server; ChatGPT is a cloud service. M1K3 is a complete on-device companion: local models plus live voice, a knowledge graph over your documents, encrypted call memory, an agent with tools, and an MCP server — one sandboxed native app.

Can Claude use my M1K3 knowledge?

Yes. M1K3 ships an MCP server exposing search_knowledge, list_documents, and get_document — Claude and other MCP clients can query your local knowledge base, locally.

Is it free?

Free for humans, forever — and open source, made by Round Tower in Ireland. No account, no subscription, no telemetry. Download the signed Mac app, join the TestFlight beta, or build from source today. If M1K3 earns a place on your Mac, there's an optional GitHub Sponsors page — it funds development, never gates features.
