Inbox OCD
Your machine. Your inboxes. Your rules.
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.

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.
