What is Zero?

zero is a macOS agent that intelligently filters your Gmail inbox each morning, keeping only threads that genuinely need your attention while reversibly archiving the rest. It uses three simple questions - Is anyone waiting on you? Is there a live consequence if you miss this? Would you regret not seeing this today? - to decide what stays. Running locally on your Mac with your own keys and no server access, zero eliminates inbox anxiety by creating a system you can trust to look for you.

Frequently Asked Questions about Zero

Does zero permanently delete emails, or can I get them back?

Nothing is ever deleted. Zero archives emails it decides don't need immediate attention, and you can recover any of them with a single search using the dated recovery labels it creates. If you want to undo an entire morning's filtering run, you can do that too.

What happens if zero archives something important by mistake?

Zero decides what stays using three specific questions: Is anyone waiting on you? Is there a live consequence if you miss this? Would you regret not seeing this today? You can read the plain language rule files that drive these decisions and modify them if the defaults don't match your needs. Any archived email is one search away from your inbox.

Does zero work on Windows or Linux?

No, zero runs only on macOS. It operates as a local agent on your Mac with no server component, which is why the platform is currently limited to Apple's operating system.

What credentials and API keys does zero need?

Zero requires your own Google account credentials to access Gmail and a Claude API key to power its filtering logic. Both keys stay on your Mac; zero has no server access and does not store them anywhere else.
