# Pairfob — AI Coding Tool Review & Pricing

> Pairfob is a tool that allows you to continue AI agent sessions running on your macOS or Linux computer from your phone, tablet, or another computer. It securely attaches to your existing live sessions rather than mirroring your desktop, ensuring that you can interact with agents like Claude, Codex, or Grok without needing to sync or tear down sessions when switching devices.
