Fazm vs Perplexity Personal Computer
A free AI agent on your own Mac vs a $200/month cloud Mac Mini. Two fundamentally different approaches to AI computer control - here's how they compare.
Your desktop vs a cloud machine. Completely different.
Perplexity Personal Computer gives AI a separate Mac Mini in the cloud to work on. Fazm gives AI control of the Mac you're already using - your real screen, your real apps, your real files.

Perplexity gives AI its own computer. Fazm gives AI control of your computer.
If you want an AI working on a separate machine in the background, Perplexity Personal Computer delivers. But if you want an AI that controls the desktop right in front of you - for free - that's Fazm.

How Fazm and Perplexity Personal Computer stack up across every dimension.
