The Problem

Your inbox is running you

You're managing client relationships, tracking opportunities, and running your business — all while drowning in newsletters, GitHub notifications, and automated alerts.

Important client messages get buried. Opportunities slip through. Your inbox controls you instead of helping you. Most email AI apps fix this by sending your emails to a cloud server — your most sensitive business conversations processed on someone else's machine.

“You're managing client relationships, tracking opportunities, and running your business — all while drowning in newsletters, GitHub notifications, and automated alerts.”

Eight categories. Zero guesswork.

The moment your email arrives, Sorto reads it and decides what matters — not with a server somewhere in a data centre, but on your device, in seconds. Every message is classified into one of eight smart categories.

→Needs Our Reply: emails waiting on you
→Opportunity: investor intros, partnerships, new business
→Active Client: ongoing conversations that matter
→Waiting on Reply: threads you've sent and are tracking

Sorto inbox categories — eight smart classifications

Command Center

The home screen answers one question: what matters right now? Reply queue at the top. Opportunities below. Active clients. Then everything else. No chronological flood. No scrolling past 40 unread newsletters to find the email you've been waiting for.

→Reply queue surfaced at the top — always
→Opportunities and active clients grouped for instant access
→Live category counts in the sidebar on iPad and Mac
→Built for one-handed iPhone use with a fast tab-based layout

Focus Mode

One thread. Full attention. Focus Mode walks you through every email waiting on your reply, one at a time. Draft an AI-assisted reply, snooze it to tomorrow, or mark it done. Clear the queue. Get back to work.

→One-at-a-time queue — no distraction, no skipping
→AI-assisted reply drafting powered by Apple Intelligence
→Snooze to tomorrow or mark done in one tap
→Clear your reply queue systematically, not randomly

Sorto Focus Mode — one thread, full attention

Sorto privacy architecture — all processing stays on your device

Privacy is the architecture

Apple's Foundation Model runs entirely on your device. We never see your email. We can't — there's no server to send it to. Your most sensitive business conversations, client details, and financial updates stay exactly where they belong: with you.

→Email content stays on your device. Always.
→OAuth tokens never leave your device
→No analytics containing personal data
→No cloud AI. No exceptions.

Frequently asked questions

Never. All classification and AI inference runs entirely on your device using Apple's Foundation Model. We have no server that receives your email content — it is architecturally impossible for us to read your messages.

Sorto connects to Gmail via full OAuth 2.0, iCloud Mail via secure app-specific password, and any IMAP-compatible account including Fastmail, Hey, and ProtonMail Bridge.

Yes. Sorto is built for iPhone, iPad, and Mac. On iPad and Mac you get a full sidebar with live category counts so you can navigate your entire inbox at a glance.

Focus Mode surfaces every email waiting on your reply, one at a time. You can draft an AI-assisted reply, snooze to tomorrow, or mark it done — clearing your queue systematically without distraction.

Sorto uses Apple's Foundation Model for deep semantic understanding of each message. Eight purpose-built categories mean it knows the difference between an active client thread and a newsletter from that client.
