M1K3 is local AI that runs entirely on your Mac. Local models, live voice, a knowledge graph that remembers everything — and a network call it never asks for.
Everything below runs inside one sandboxed app on Apple Silicon. Pull the ethernet cable — M1K3 doesn't notice.
Three brains: Mini answers instantly, Lil fronts the conversation, and Big is delegated the deep work. Switch in Settings any time — which models, and how they score.

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. Even the thumbs-up/down feedback you leave on answers stays local — it's yours, for tuning, and no visiting agent can read or write it. The optional web-search tool is off by default and clearly toggled.
Three brains, all local: Mini for instant answers, Lil — the fast brain that fronts the conversation — and Big, delegated the deep work. Switch in Settings any time; the models behind each name, and their scores, live on /brains.
Only if you ask it to. The Heartbeat is an ambient pulse — every two hours, a short narrative about your machine and your day, composed from facts the code gathered, respecting quiet hours. Off by default, one-tap Clear, never enters your chat transcript. There's also a native screensaver — the pixel M in ambient rain — installable from Settings.
That's Brain at Home: your Mac serves its brain to your own devices over the local network — Bonjour discovery, one-time QR pairing, TLS-PSK encryption, and a scoped read-only tool set for paired devices. Off by default; nothing ever crosses the internet.
Apple Silicon Macs on macOS 26 Tahoe. M1K3 is a native SwiftUI app with Metal-accelerated inference — not an Electron wrapper.
Ollama is a local model server; ChatGPT is a cloud service. M1K3 is a complete on-device AI app: 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.
Yes. M1K3 ships an MCP server with 16 tools — search_knowledge, ask_m1k3, memory recall, documents, even speak — over local HTTP at 127.0.0.1:4242. Long asks get an async job API. Claude and other MCP clients query your local knowledge base, locally.
Free for humans, forever — and open source under Apache-2.0, made by Round Tower in Ireland. No account, no subscription, no telemetry. Download the signed & notarized 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.
M1K3 for Mac is ready to download. Free for humans, forever — run it on your own Mac, or build it from source.
Free, and staying that way. If it earns a place on your Mac, you can sponsor its development — optional, never nagged.
