Inbox Zero Mail is live!
Introducing Inbox Zero Mail.
The open-source Superhuman alternative.
- Fast and keyboard-first
- Unified inbox across Gmail and Outlook
- Split inboxes
- AI categorization and drafts
- Bulk unsubscribe
- Team collaboration
Runs on web, desktop, and native iOS.
Free to use. AI is $20/mo, half Superhuman’s price. Open source, so you can self-host for free too.
This isn't an overnight vibe-coded project. I've been running Inbox Zero for 3 years: 12k GitHub stars, 25k+ sign-ups, and enterprise customers.
Until today, Inbox Zero was an AI assistant for Gmail and Outlook. It still is. But now we have our own email app too.
We're SOC 2 compliant, and have undergone multiple pentests, including recent ones from OpenAI and Snyk using unreleased cyber models.
Try it: getinboxzero.com
An assistant you brief once. Tell Inbox Zero how you want email handled, and the AI runs your inbox on its own: sorting, labeling, drafting replies. You set the rules. It does the work while you're elsewhere.

Imagine running your inbox by just saying what you want. "Archive every newsletter older than a week." "Label anything from a customer as urgent." With Inbox Zero's AI chat, plain English is the only setting screen you need.
Most emails don't need a reply. The few that do get buried under the ones that don't. Reply Zero surfaces only the threads actually waiting on you, so nothing important slips and you stop scrolling past it.
Contracts and invoices buried in email threads, never where you need them. Inbox Zero auto-files attachments straight to Google Drive or OneDrive as they arrive. Findable later, no digging.
21,000+ people have signed up for Inbox Zero. Open source, self-hostable, works on Gmail and Outlook. The AI email assistant that actually does the boring parts for you.
Spend 10 minutes a day deciding where each email goes? Inbox Zero auto-labels and files everything the moment it lands. You open Gmail to a sorted inbox, not a pile of decisions.
You don't always want to open Gmail to clear email. Inbox Zero lets you read and reply right from Slack or Telegram. Triage between meetings without opening the inbox at all.
Sales reps: a prospect asks for a demo, and 4 emails later you still haven't booked it. Inbox Zero checks your calendar and drafts the reply with 3 open slots. Reply once, done.
An AI assistant touching your email should clear your security team first. Inbox Zero is SOC 2 Type 2 certified and fully open source, so there's nothing hidden to trust.
Cold outreach is fine. A cold pitch landing on top of your real work is not. Inbox Zero spots cold emails and keeps them out of your way, so the inbox you open is the one that matters.
Gmail search queries worth saving:
is:important is:unread
has:attachment larger:10M

Our free Chrome extension turns any of these into a permanent tab in Gmail.
Build-in-public update: Inbox Zero now runs on Outlook, not just Gmail. It was rough at first, but we've ironed out the bugs. Same AI organizing, drafting, and calendar replies, wherever you live.
Email rules used to mean clicking through fiddly filter menus. Now you just write it in plain English: "label anything from a customer as Important and draft a reply." Inbox Zero does the rest.
Your inbox isn't messy because you're lazy. It's 200 newsletters you never agreed to read. Inbox Zero bulk unsubscribes and archives them in a few minutes.
AI that writes emails for you usually sounds like AI. Inbox Zero learns your voice and drafts replies that read like you wrote them. You review and send. The blank reply box dies.
Our Chrome extension brings Superhuman-style split-inbox tabs to plain Gmail. To Reply, Newsletters, Receipts, each its own tab. Free, no signup, 100% client-side.
Most AI email tools are a black box you have to trust with your inbox. Inbox Zero is open source. 11k stars, self-hostable, every line public. Read the code, then decide.
