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.
| Feature | Collie | Hermes |
|---|---|---|
| Hardware needed | Your existing PC | Requires buying a device |
| Tool connections | Unlimited connectors | Limited built-in tools |
| Persistent agents | Yes — permanent memory | Session-based only |
| Approvals & control | Full approval workflow | Minimal control |
| Model choice | Any API provider | Locked to onboard model |
| Cost | Free & open source | Hardware purchase + subscription |
| Open source | MIT licensed | Proprietary hardware |
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.
