|---|---|---|
| Built for | A general agent you need to continually maintain, secure, and fix. | A personal assistant that knows you and your life, for everyday jobs. |
| You open | Chat apps, a terminal, or a desktop window. | A Mac app. |
| From your phone | Tailscale, then Telegram. You send a text and cannot tell what it is doing, or when it finished. | The same app on your phone. Encrypted remote access. |
| Mail and calendar | MCP round trip, 2 to 8 seconds. | Local full corpus search, ~20-50ms. |
| Your brain | Whatever the agent dumps on disk. | An organized wiki. Use your Obsidian vault, or grow pages from mail and files in minutes. |
| Your data | Local. You hold it. | Local. You hold it. |
| The model | The slowest, most expensive frontier models. | Faster, cheaper models are often enough. Save hundreds a month. |
| Security | The agent gets a shell and marketplace skills. One bad skill can leak keys or run code on the machine. You are the security team. | No shell. Fixed tools. Secrets in the Keychain. |
