Inbox OCD

One inbox for Gmail and Outlook.
Governed by you, reversibly.

Inbox OCD is a desktop email app for macOS and Windows. It pulls your Gmail and Outlook accounts into a single inbox and gives you one set of sender rules that spans both — file, mute, VIP, or unsubscribe a sender once, everywhere. Supported mail actions can be reviewed and reversed through the action journal.

Download Inbox OCD

Download for Mac

Apple silicon Macs (M1 or newer), macOS 11+

Download for Windows

Windows 10 or 11, 64-bit

Outlook: free to try, no card needed. Connect your Outlook or Microsoft 365 account and go.

Gmail: invite-only for now. Google is still reviewing Inbox OCD, and until it finishes Google only lets a limited number of Gmail accounts connect. Founder Licenses get those spots first. Request a Gmail invite.

On your phone: a companion app for mobile is coming soon.

If Windows says “Windows protected your PC”, click More info, then Run anyway. Already have Inbox OCD? Updates arrive inside the app as usual.

Truly cross-provider

Gmail and Microsoft Outlook in one view, with label rules and per-sender policies that apply across both accounts at once — something neither provider offers.

Reversible by design

Filing, trashing, and snoozing are visual first; nothing touches your real mailbox unless you opt in. An action journal records every batch — supported actions can be undone. Calendar deletion requires confirmation and cannot be undone inside Inbox OCD.

Local-first & private

Desktop mail sync runs directly between your computer and Google or Microsoft, with rules and sign-in tokens stored on your device. Details are in our privacy policy.

No cloud AI

Inbox OCD does not send your email to any AI service. Your messages stay between your device and your mail provider.

How Inbox OCD uses your Google and Microsoft data

Inbox OCD is a desktop email client. With your permission, it connects to your Gmail account (read, label, and send mail; read your calendar) and your Outlook account (read and send mail) to display your messages, file them according to rules you create, and send email you compose. Desktop mail sync is direct to your device. Google access also supports filter import, Other Contacts email matching and confirmed calendar-event deletion. Inbox OCD does not send message content to any AI service.

Inbox OCD's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Details in our privacy policy.
