Everything you need to run a calm inbox
One unified workspace for Gmail and Office 365, powered by AI that runs on your Mac.
AI that files your email the way you would
Every message is analysed and assigned to the right category automatically. When you recategorise, InboxZebra learns — accuracy improves the more you use it.
- Automatic categorisation across all accounts
- Learning system that adapts to your corrections
- Per-account instructions and global rules
- Natural-language AI search
Your email backlog, as a GTD workflow
Actionable emails become tracked tasks that move through clear stages, with reply detection so you always know what you're waiting on.
- Inbox → Next → Waiting → Someday → Done
- Automatic reply detection for waiting items
- Create tasks from any email in one click
- Priorities and due dates
A cleaner inbox without the unsubscribe chore
InboxZebra detects newsletters, surfaces the ones you never open, and lets you unsubscribe in a click — while protecting senders you care about.
- Smart unsubscribe detection
- Low-engagement subscriptions flagged for review
- Preferred-sender lists that never get filtered
Process hundreds of emails at once
Select across accounts and archive, delete, or recategorise in bulk. Clear a backlog of thousands in minutes, with real-time progress.
- Multi-select with keyboard shortcuts
- Bulk archive, delete, and recategorise
- Date-range processing with automatic pagination

Your data stays on your Mac
Privacy isn't a setting — it's the default.
We never train on your data
Your emails are never used to train models or improve results for anyone else. Learning examples stay on your Mac.
Local AI by default
BusinessCategorisation runs locally via Ollama on every tier. Business tier optionally adds cloud AI (Gemini) with your own API key.
Encrypted storage
Email bodies are encrypted with AES-256-GCM in Core Data. OAuth tokens are stored only in the macOS Keychain.
