Inbox Zero Mail: an open-source alternative to Superhuman
Inbox Zero, an AI email assistant that's been around for three years, launched its own email client and was the top Product Hunt launch on 18 October. It puts several Gmail and Outlook accounts in one fast, keyboard-first inbox on web, Mac, Windows and iPhone, with split inbox, bulk unsubscribe and private team comments. The client is free; the AI that sorts every email and drafts replies in your voice is $20 a month, and you can self-host it.
Why it mattersA cheaper way to get Superhuman-style email speed with AI drafts, and the open source code means you're not locked in.
