Your personal Mac assistant. Built-in apps. Voice messages. Secure by default. No setup headaches.
Your Mac is already set up. Why should an AI make you do it again with OAuth and gateways?
Son of Simon is an AI assistant for macOS that works directly with your Apple apps — Mail, Calendar, Reminders, Notes, Safari, Contacts, Messages, and Things3. It runs with cloud providers (Anthropic, OpenAI, Google Gemini, OpenRouter) or fully offline on your Mac using Pico AI Server — no API key needed for local models. Add your account in Apple Mail/Calendar and the agent can use it. You do not need to code. Download the app, sign in, and start asking.

The setup wizard will guide you through:
- Connecting your AI provider (Anthropic, OpenAI, Google Gemini, OpenRouter, or Pico for local models)
- Choosing a model (Claude, GPT-5, DeepSeek, Gemini, Llama, or any model running locally)
- Granting macOS permissions
- Optional Telegram setup
First success (safe demo prompts):
- "What's on my calendar today? (Read-only.)"
- "Summarize my unread emails and highlight anything urgent. Don't reply or send anything."
- "Search my Notes for anything about <keyword> and summarize what you find."
Son of Simon comes with built-in skills for Mail, Calendar, Reminders, Notes, Safari, Contacts, Messages, Things3, System Controls, Scheduled Tasks, Browser Automation, Downloads Organizer, Image Generation, and Data App Creator. Skills use the AgentSkills standard — community skills from ClawHub work out of the box. See docs/SKILLS.md for custom skills, CLI commands, and ClawHub install instructions.
Works with cloud providers — Anthropic, OpenAI, Google Gemini, and OpenRouter — or run models locally on your Mac with Pico AI Server. No API key needed for local models. Gemini models support native image generation. Pick a provider during setup or switch any time. See docs/AI_PROVIDERS.md for the full model table.
Son of Simon remembers context between conversations — preferences, habits, and patterns — in a local memory file (~/.macbot/memory.yaml). You can read, edit, or delete it at any time. The heartbeat (~/.macbot/heartbeat.md) runs a prompt periodically while the service is active, useful for recurring checks like scanning for urgent emails or upcoming meetings. All data stays on your Mac under ~/.macbot/.
- macOS
- Apple apps configured (Mail, Calendar, Reminders)
- An AI provider: cloud API key or Pico AI Server for fully offline local inference
- Optional: Telegram bot for remote access
No stored passwords — macOS Keychain handles authentication. No local gateway required — AppleScript talks to your apps directly. Your prompts go to your chosen LLM provider; nothing else leaves your Mac. See docs/SECURITY.md for the full security model and privacy details.
Create recurring or one-shot scheduled tasks through natural language or the dashboard GUI. Uses cron expressions with timezone support. Useful for daily email summaries, meeting prep, or periodic reminders.
- Microsoft Teams — Ask the agent to "set up Teams". The Azure CLI (
brew install azure-cli) handles the Azure AD app registration so you never need to navigate the Azure Portal. Supports multiple accounts (e.g., work + personal tenant). See Teams setup guide for details. - Mindwtr GTD — Full GTD task management via direct file sync (set
