inbox-zero

Inbox Zero is an open source AI assistant for email, designed to help people spend less time managing their inbox. It connects to Gmail and can also work through Slack or Telegram, so you can deal with email without opening your mail app directly.

The core feature is an AI assistant that reads your inbox, organizes it, and pre-drafts replies in your tone and writing style. You describe how you want your email handled in plain English, and the AI follows those instructions as rules. For example, you could tell it to archive all newsletters, or to draft a reply whenever a client asks about pricing. Beyond drafting, it tracks which emails still need a reply and which are waiting on someone else, so nothing slips through.

Several additional features help with inbox maintenance. A bulk unsubscriber lets you leave mailing lists in one click and archive all past messages from them. A cold email blocker automatically removes unsolicited sales outreach. An attachments feature saves email attachments to Google Drive or OneDrive. Meeting briefs pull context from your email and calendar to give you a summary before each meeting. There is also basic email analytics to show your activity patterns over time.

A hosted version is available at getinboxzero.com for people who want to get started without any setup. For those who want to run it themselves, the README provides a self-hosted path using a command-line tool that automates the setup, or a manual local development path for contributors. Both require Docker. The app is built with Next.js, uses PostgreSQL for storage, and integrates with Upstash for background job handling.

The project is open source and the team welcomes contributions through GitHub issues and a Discord community.
