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.

// built native

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?

Google Gemma locally via MLX-Swift on Apple Silicon, with Apple Foundation Models handling fast turns. Hot-swap runtimes in Settings, mid-conversation.

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. 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.


// now in open beta

Own your AI.

M1K3 for Mac is on TestFlight now. Free for humans, forever — run it on your own Mac, or build it from source.

Join the TestFlight beta Build from source

Free, and staying that way. If it earns a place on your Mac, you can sponsor its development — optional, never nagged.
