Execution Model

Fully local agent vs cloud-to-desktop hybrid

Both Fazm and Manus now have desktop apps, but they work very differently under the hood. Fazm runs entirely on your Mac - screen analysis, task execution, and control logic all happen locally. Manus My Computer installs a desktop app that can access your local files and apps, but the AI reasoning still happens in Meta's cloud. You send instructions, they go to Meta's servers for processing, and the results come back to execute on your machine.

F
Fazm
  • AI processing runs on your Mac
  • Real-time interactive control
  • No cloud round-trip for execution
  • Works offline for core functions
M
Manus AI
  • Desktop app connects to Meta's cloud AI
  • Local file access but cloud reasoning
  • Can trigger tasks remotely from phone
  • Requires internet connection
App Coverage

Accessibility API control vs CLI and app launching

Fazm uses macOS accessibility APIs to deeply control any native app - clicking buttons, reading UI elements, navigating menus in Xcode, Final Cut Pro, Slack, and thousands more. Manus My Computer interacts with your desktop primarily through terminal commands and app launching. It can open applications and run CLI instructions, but does not use accessibility APIs for fine-grained UI control the way Fazm does.

F
Fazm
  • Deep accessibility API integration
  • Click, type, navigate any app's UI
  • System preferences and settings
  • Fine-grained control of any interface element
M
Manus AI
  • CLI command execution on your machine
  • Can launch and interact with apps
  • File reading, editing, and organization
  • Uses terminal as primary interface to your system
Voice Input

Voice-first interaction vs text-only input

Fazm treats voice as the primary interface. Press a keyboard shortcut, speak your task, and execution begins immediately on your desktop. Manus My Computer, like the cloud version, still relies on text input - you type your instructions in the desktop app or web interface. For fast-moving workflows and hands-free use cases, Fazm's voice-first design is a clear differentiator.

F
Fazm
  • Push-to-talk starts execution instantly
  • Natural language voice commands
  • No typing required
  • Works hands-free
M
Manus AI
  • Text input in desktop app or web UI
  • No voice input of any kind
  • Must type instructions
  • Not suitable for hands-free use
Privacy

Fully local vs cloud-dependent processing

When Fazm analyzes your screen, that processing happens on your Mac. With Manus My Computer, file operations happen locally, but every instruction is sent to Meta's cloud for AI processing. While Manus says file data stays local unless you ask for cloud summaries, the AI reasoning about your tasks still runs on Meta's servers. For confidential work, Fazm's fully local architecture avoids this concern entirely.

F
Fazm
  • Screen analysis is fully local
  • Files stay on your machine
  • No cloud dependency for core use
  • Suitable for confidential workflows
M
Manus AI
  • File ops local, AI reasoning in cloud
  • Instructions processed on Meta servers
  • Data subject to Meta's privacy policy
  • Requires trust in cloud handling of task context

About each product

M

Manus AI

by Meta

General-purpose AI agent acquired by Meta that handles multi-step tasks across web browsing, code execution, file management, and data analysis. In March 2026, Manus launched My Computer - a desktop app for macOS and Windows that brings its cloud agent to your local machine. My Computer can access local files, launch apps, and run terminal commands, but the AI reasoning still processes through Meta's cloud. Paid plans start at $20/month for full My Computer access.
