Sorto: AI email client

Private AI email client that classifies and ranks emails on-device using Apple Intelligence, with no cloud processing.

Introduction

Sorto is the first email intelligence app built entirely on Apple Intelligence — the on-device Foundation Model. Every email is read, classified, and ranked on your device. Nothing you write or receive ever leaves your iPhone, iPad, or Mac.

Key Features:

  • On-Device AI: Uses Apple's on-device Foundation Model for email classification, ensuring privacy.
  • Smart Categories: Automatically sorts emails into 8 categories: Needs Our Reply, Opportunity, Active Client, Waiting on Reply, Important Ops, Platform Update, Noise.
  • Command Center: Home screen prioritizes what matters: reply queue, opportunities, active clients.
  • Focus Mode: Walks through emails waiting for reply one at a time, with AI-assisted drafting, snooze, or mark done.
  • Privacy: Email content stays on device; OAuth tokens never leave; no cloud AI; no analytics with personal data.
  • Account Support: Gmail (OAuth 2.0), iCloud Mail (app-specific password), any IMAP account (Fastmail, Hey, ProtonMail Bridge, etc.).
  • Cross-Platform: Optimized for iPhone, iPad, and Mac with adaptive layouts.

Use Cases:

  • Professionals managing high-volume email who need prioritization.
  • Privacy-conscious users wanting AI email assistance without cloud exposure.
  • Teams tracking client communications and opportunities.
