How much time will I actually save with Fazm?

Most users report saving 45-90 minutes per day on repetitive tasks. The biggest time savings come from email management (drafting replies, sorting, archiving), form filling (expense reports, CRM updates, applications), research (comparing products, gathering data from multiple sites), and social media (cross-posting, scheduling, replying). For example, booking a flight that normally takes 10 minutes of clicking through airline sites takes a single voice command with Fazm. Filing an expense report that requires opening a PDF, extracting numbers, and entering them into a spreadsheet becomes one spoken sentence. The more repetitive and multi-step your daily work is, the more time you get back.

What exactly can Fazm control?

Fazm controls everything you can do manually on your Mac. That includes mouse movements and clicks, keyboard typing, browser navigation and form filling, app switching, file management in Finder, and system-level actions. It uses direct browser DOM control for web interactions - meaning it reads and manipulates the actual page structure rather than taking screenshots and guessing where to click. For native macOS apps, Fazm uses accessibility APIs to interact with buttons, menus, text fields, and other UI elements. This works across any application: Chrome, Safari, VS Code, Slack, Figma, Terminal, Mail, Calendar, and more.

How is Fazm different from ChatGPT or Claude?

Chatbots like ChatGPT and Claude give you answers in a conversation window. Fazm takes action directly on your computer. When you say 'reply to Sarah's email,' Fazm opens your email app, finds Sarah's message, writes a contextual reply, and sends it. A chatbot would tell you what to write, but you still have to do all the clicking and typing yourself. Fazm moves your mouse, types on your keyboard, clicks buttons, and navigates between apps. It is a computer agent, not a chat assistant.

How does the memory layer work?

Fazm builds a personal knowledge graph by extracting information from your files, browsing history, conversations, and daily activity. Over time, it learns your contacts (names, emails, relationships), accounts and credentials, preferences (formatting, tone, scheduling habits), and frequently used workflows. In your first week, you might say 'Reply to Sarah's email, she's my cofounder, her email is sarah@acme.com.' By week four, you just say 'Reply to Sarah' because Fazm already knows who she is. By week eight, Fazm can draft the reply before you even ask. All of this data stays locally on your Mac - your knowledge graph never leaves your machine or gets sent to any cloud service.

Is Fazm safe? Can it mess up my computer?

Safety is built into every layer of Fazm. You watch every action in real-time on your screen - Fazm moves your mouse and types visibly, so there is nothing hidden. You can stop any action at any point by pressing a keyboard shortcut. Fazm also shows you what it plans to do before executing destructive actions like deleting files or sending emails, giving you a chance to confirm or cancel. Because Fazm is open source, the code is fully auditable on GitHub. There is no hidden behavior, no background processes making changes you cannot see, and no actions that bypass your screen.

What platforms does Fazm support?

Fazm currently supports macOS, running natively on both Apple Silicon (M1, M2, M3, M4) and Intel Macs. It is built with Swift and uses macOS-specific frameworks like ScreenCaptureKit for screen analysis and Accessibility APIs for app control, which is why macOS is the primary platform. Windows and Linux support are on the roadmap but do not have release dates yet. You can also control your Mac remotely from your phone using Fazm Remote, which gives you voice access to your desktop while you are away from your computer.

How does Fazm voice input work?

One keyboard shortcut activates push-to-talk. Hold the key, speak naturally about what you need done, and release. Fazm transcribes your speech locally using on-device models, so there is no network latency for the voice recognition step. You do not need wake words like 'Hey Siri' or 'OK Google' - just press and talk. You can also type commands into the floating toolbar if you prefer text input. Fazm understands natural language, so you do not need to memorize specific commands. Say 'book me a flight to Tokyo next Thursday' or 'find the cheapest AirPods on Amazon' and Fazm figures out the steps.

Is my data sent to the cloud?

Fazm processes screen analysis and memory entirely on your machine. The personal knowledge graph, file indexing, and screen capture all run locally. The only data that leaves your Mac is the intent - a text description of what you want to accomplish, which is sent to the AI model (Claude or GPT) for action planning. Your actual screen content, file contents, browsing history, and personal knowledge graph never leave your computer. Fazm is also open source, so you can verify exactly what data is transmitted by reading the code on GitHub. For users who need complete air-gapped operation, local model support is planned.

Why Uptime Percentages Are Misleading for AI Agent Deployments

Uptime Lies

Your AI agent system reports 99.9% uptime. That sounds great until you realize that the 0.1% downtime happened all at once, across every agent, during the one hour your customer needed it most.

Uptime percentages hide the thing that actually matters - co-failure. When multiple agents or services fail simultaneously, the impact is catastrophic. When they fail independently, the system degrades gracefully. Same uptime number, completely different user experience.

What Co-Failure Looks Like

Co-failure happens when your agents share dependencies:

Same LLM provider. All five agents call Claude API. When Anthropic has an outage, all five agents go down at once. Your uptime dashboard shows a brief dip. Your users experienced total system failure.
Same rate limits. Multiple agents sharing one API key hit rate limits together. They do not fail one at a time - they all start failing at the same moment.
Same infrastructure. Agents running on the same machine, same network, same cloud region. A single hardware failure takes everything down.
Same context dependency. If all agents depend on the same upstream data source and that source returns bad data, every agent produces wrong results simultaneously.

Why the Metric Misleads

Traditional uptime treats all downtime as equal. Five minutes spread across five days is the same percentage as five minutes in one block. But operationally, these are completely different:

Distributed failure - one agent down at a time, others compensate. Users barely notice.
Correlated failure - everything down at once. Users see a total outage.

The uptime number cannot tell you which one you have.

What to Track Instead

Mean time between correlated failures. How often do multiple agents fail at the same time?
Blast radius. When one component fails, how many agents are affected?
Independence score. What percentage of your agents can keep running if any single dependency goes down?
Recovery spread. After a failure, do all agents recover at once or do they stagger?

Build for independent failure. Use multiple LLM providers. Run agents on separate infrastructure where possible. Make your agents able to degrade gracefully instead of failing together.

Fazm is an open source macOS AI agent. Open source on GitHub.
