Collie vs Hermes

Collie runs on your existing PC. Hermes is a dedicated hardware device. Different approaches to the same problem.

What is Hermes?

Hermes is a physical AI assistant device — a small box you plug in that provides AI-powered voice and text interactions. It's hardware-locked, less extensible, and requires purchasing dedicated equipment.

The bottom line

Hermes is convenient if you want a dedicated AI hardware device. But Collie gives you more flexibility, connects to your actual tools (calendar, files, email), and lets you switch models anytime. Plus it's free — no hardware to buy.
