One app. Any AI. Total command over your Mac.

Agent! wires 17 LLM providers — Claude, GPT, Gemini, Grok, Mistral, DeepSeek, Qwen, Z.ai, BigModel, Hugging Face, Ollama (cloud and local), vLLM, LM Studio, Codestral, Mistral Vibe, and on-device Apple Intelligence — into a native macOS app that doesn't just talk about doing things. It does them.

Watch it read your codebase, fix the bug, build the Xcode project, and commit the diff while you make coffee. Tell it to open Safari and text you the price of flights to Tokyo. Say "Agent!" from across the room and have it run your test suite by voice. Text your Mac from iMessage and get a polished answer before you reach your car.

It edits files with surgical string-replace diffs — every change one-click undoable from a Time-Machine-style rollback. It drives any Mac app through the Accessibility API — no AppleScript required. It remembers your preferences across sessions. It spawns parallel sub-agents for work that fans out. It indexes entire codebases into a portable JSONL repo-map that any LLM can consume. It runs shell commands as you, or as root via a Launch Daemon you approve exactly once.

Bring your own API key. Run it fully local on Ollama, vLLM, or LM Studio. Or run it free, forever, on Apple Intelligence. No subscription. No telemetry. No vendor lock-in. Your keys, your machine, your data.

Download it. Say what you need. Watch it happen.

Quick Start (Download)

1. Download Agent! and drag to Applications
2. Open Agent! -- it sets up everything automatically
3. Pick your AI -- Settings → choose a provider → enter API key

Quick Start (Build from Source)

1. Clone the repository:

   git clone https://github.com/toddbruss/Agent.git
   cd Agent
   

Option A: Build with Xcode (Apple Developer account)

2. Open Agent.xcodeproj in Xcode.
3. Build and Run the Agent target.
4. Approve the Helper Tool: When prompted, authorize the privileged daemon to allow root-level command execution.

Option B: Build without an Apple Developer account

2. Run the build script (requires only Xcode Command Line Tools):

   ./build.sh              # Debug build
   ./build.sh Release      # Release build
   

3. The app lands in build/DerivedData/Build/Products/Debug/Agent!.app
4. Run it: open "build/DerivedData/Build/Products/Debug/Agent!.app"

⚠️ Without a developer account the app is ad-hoc signed. The Launch Agent/Daemon helpers won't register (SMAppService needs a team ID), but the LLM loop, all tools, accessibility, AppleScript, shell, and MCP all work.

Then:

5. Configure your AI Provider: Go to Settings and enter your API key or select a local provider like Ollama.

💡 Cheapest cloud path? GLM-5.1 (the latest) is now available on all four of the cheap cloud providers — Ollama, Hugging Face, Z.ai, and BigModel. Pennies per million tokens vs Claude/GPT pricing. Pick whichever you already have an account with; pricing is competitive across all of them.

💡 Z.ai is still the recommended starting point if you don't have an account anywhere yet — fastest signup, GLM-5.1 is the default model, no infrastructure to provision.

⚠️ Running GLM locally? Only GLM-4.7-Turbo (32B) runs well on consumer hardware — M2/M3/M4 Mac with 64-128GB unified memory via Ollama. GLM-5 (744B MoE) and GLM-5.1 (754B MoE) are too large to run locally (~1.6TB full weight) — use them via Z.ai, BigModel, Hugging Face cloud, or Ollama cloud.

What Can It Do?

"Play my Workout playlist in Music" "Build the Xcode project and fix any errors" "Take a photo with Photo Booth" "Send an iMessage to Mom saying I'll be home at 6" "Open Safari and search for flights to Tokyo" "Refactor this class into smaller files" "What calendar events do I have today?"

Just type what you want. Agent! figures out how and makes it happen.

Key Features

🧠 Agentic AI Framework

Built-in autonomous task loop that reasons, executes, and self-corrects. Agent! doesn't just run code; it observes the results, debugs errors, and iterates until the task is complete.

🛠 Agentic Coding

Full coding environment built in. Reads codebases, edits files with precision, runs shell commands, builds Xcode projects, manages git, and auto-enables coding mode to focus the AI on development tools. Replaces Claude Code, Cursor, and Cline -- no terminal, no IDE plugins, no monthly fee. Features Time Machine-style backups for every file change, letting you revert any edit instantly.

🔍 Dynamic Tool Discovery

Automatically detects and uses available tools (Xcode, Playwright, Shell, etc.) based on your prompt. No manual configuration required for core tools.

🛡 Privileged Execution

Securely runs root-level commands via a dedicated macOS Launch Daemon. The user approves the daemon once, then the agent can execute commands autonomously via XPC.

🖥 Desktop Automation (AXorcist)

Control any Mac app through the Accessibility API. Click buttons, type into fields, navigate menus, scroll, drag -- all programmatically. Powered by AXorcist for reliable, fuzzy-matched element finding.

🤖 17 AI Providers

The provider picker (LLM Settings, toolbar button #7) shows 16 providers; Apple Intelligence is reached via the separate brain icon (#8). Source of truth: AgentTools.APIProvider.

💡 Self-hosted "free" providers (Local Ollama, vLLM, LM Studio) are only free in the API-fee sense. Running a 30B+ model with usable speed needs an M2/M3/M4 Ultra Mac Studio (64-128GB unified
