quincy.wtf

An AI assistant that runs on your Mac — privately, securely, and under your control.

Made for Mac users by a Mac user.

# Your data stays on your machine

Quincy can run AI models directly on your Mac — no internet connection required, no data sent anywhere. If a task needs more horsepower, you can connect a cloud provider for faster, more accurate responses. You choose what stays local and what goes to the cloud.

# The AI only does what you allow

Most AI assistants have open-ended access to your computer. Ask one to “clean up my inbox” and it might delete emails you wanted to keep.

Quincy works differently. Each task is handled by a specialist agent with a specific set of tools and permissions. An email agent might read your inbox and suggest calendar appointments — but it literally cannot reply, delete, or take any action you haven’t allowed. These aren’t suggestions; they’re hard limits enforced before any action is taken.

# Use it everywhere

Start a conversation on your Mac, pick it up on your iPhone. The server runs on your Mac (or a dedicated machine); the command line, macOS app, and iOS app are lightweight clients that connect to it. Your agents, models, and conversation history stay in one place.

# Extend with any tool

Quincy comes with built-in tools, but you can connect it to almost anything — task managers, calendars, email, smart home devices, databases. Ask Quincy to set up a connection and it walks you through it. You control which tools each agent can see and what actions require your approval.

# Under the Hood

For developers and tinkerers

llama.cpp + GGUF

Local inference via llama-server in router mode. Each agent can target a different model.

Anthropic Claude

First-class cloud provider. Use locally, in the cloud, or both — per agent.

MCP Protocol

Connect any MCP server. Bridge external tools with approval policies and scoped access.

HMAC-Signed Configs

Every config is cryptographically signed. Keychain-backed root key with HKDF derivation.

macOS Keychain

All secrets stored in the Keychain. The LLM never sees your credentials.
