MailMind is a native iOS email client that uses AI to triage, summarize, and translate your inbox — so you spend less time reading and more time responding to what actually matters. WHY MAILMIND Your inbox is noisy. Bank alerts, subscription renewals, package deliveries, security codes, promotions, and the occasional real message from a human all compete for attention. MailMind reads each email on your device and gives you a clear, color-coded picture of what's happening and what needs action. AI-POWERED SMART INBOX • Urgency detection — every message is tagged high / medium / low so you know what to open first • Plain-language summaries — a one-sentence explanation of what each email means • Suggested actions — "Act now", "Act this week", "Review only", or "Archive" — based on the message content • Entity extraction — amounts, currencies, organizations, and deadlines pulled out automatically • Smart categories — security, billing, transactions, promotions — filter your inbox with one tap MULTIPLE PROTOCOLS, MULTIPLE PROVIDERS • IMAP and POP3 support for virtually any mail provider • Region presets for iCloud, Outlook, Yahoo, Zoho, Proton Mail, QQ, NetEase 163/126, Sina, Yahoo! Japan, DOCOMO, OCN, and more • Custom IMAP setup for self-hosted or enterprise servers • Full send support with attachments, drafts, and threading MULTILINGUAL AI MailMind understands email in English, Chinese, and Japanese — and generates AI summaries in whichever language you prefer. Perfect for anyone who sends and receives mail across languages. PRIVACY-FIRST DESIGN • No developer-operated server stores your email • All messages live on your device; credentials are stored in the iOS Keychain • AI processing is user-initiated only — a message goes to our AI gateway just for that one request and is never retained, logged, or used for training • No trackers, no ads, no analytics SDKs NATIVE iOS Built from scratch with SwiftUI. Dark mode, dynamic type, haptics, multi-account, swipe actions, pull-to-refresh, and a bottom tab bar that feels at home on iOS 17 and later. TRY DEMO MODE Not ready to connect your email? Tap "Try Demo" on the add-account screen to explore MailMind with sample messages, pre-baked AI analyses, and all categories — no credentials required. REQUIREMENTS • iOS 17 or later • Compatible with iPhone and iPad • Optional: an email account with IMAP/POP3 access MailMind does not require a subscription. There are no in-app purchases, no ads, and no account signup with the developer.
