About Inbox Zero

What the tool does and who it's for

Inbox Zero is an open-source AI email assistant designed to automate the path to an empty inbox. It leverages large language models to categorize incoming mail, generate draft replies in the user's specific tone, and provide automated rules written in plain English. Beyond simple filtering, it offers tools for bulk unsubscribing from newsletters, blocking cold emails, and generating pre-meeting briefings by scanning relevant email threads and calendar events. The tool is built with a focus on privacy, offering a self-hosted version for users who want complete control over their data, while the hosted version integrates directly with Gmail and Outlook.
