What is Inbox Zero?
Inbox Zero is an open-source AI email assistant and email app for Gmail and Outlook. The assistant works in the background: it sorts and labels mail, pre-drafts replies in your tone, follows plain-English rules you write, tracks what needs a reply, blocks cold email, bulk-unsubscribes and archives, files attachments to Google Drive or OneDrive, and sends briefings before meetings.
You can chat with it from Slack or Telegram to manage your inbox on the go. The separate email client offers a split inbox, multiple accounts and team comments, and is free on web, desktop and iPhone. The code can be self-hosted, and the hosted service has paid plans with a 7-day free trial.
