The ChatGPT macOS Desktop App Is Great - Until You Need Cross-App Automation
The ChatGPT macOS desktop app gets one thing very right - the floating window you summon with Option+Space. It's fast, it stays on top, and it makes asking questions while working feel natural. As a chat interface on your desktop, it's genuinely good.
But the moment you need it to do something beyond answering questions, the limitations become obvious.
What It Can't Do
The ChatGPT desktop app can read your screen (if you let it) and answer questions about what's visible. That's useful. What it cannot do is take action. It can't click buttons in other apps. It can't fill out a form in your browser. It can't move files, update a spreadsheet, or chain together steps across multiple applications.
This means every workflow still requires you to be the middleman. The AI gives you an answer, and then you manually go execute it. For quick questions, that's fine. For anything involving multiple steps across apps, you're doing all the actual work yourself.
The Gap Desktop Agents Fill
A desktop agent like Fazm works differently. It uses macOS accessibility APIs to actually control your applications - clicking, typing, navigating, and automating multi-step workflows across any app on your Mac.
The difference isn't about intelligence. ChatGPT is plenty smart. The difference is about agency. One answers questions while you work. The other does the work while you supervise.
If your workflow is "ask a question, get an answer, go do the thing yourself" - the ChatGPT desktop app is great. If your workflow is "tell the computer what to do and let it handle the steps" - you need something that can actually control your Mac.
Fazm is an open source macOS AI agent. Open source on GitHub.
