What Chuck is
Chuck is an iOS email client for reading, replying, composing, and managing accounts in one place. It supports Gmail, Outlook, Yahoo, iCloud, AOL, and any IMAP provider. Messages can be grouped by sender, date, size, and other criteria so users can delete, archive, or move many at once. On-device AI surfaces messages likely to be deleted to assist inbox triage. Chuck says processing happens on the device and that it does not store email content or message metadata on its servers. Its backend is hosted on IBM Cloud, with TLS encryption in transit and encryption at rest. Google, Microsoft, and Yahoo accounts use OAuth2, while iCloud uses an Apple app-specific password. The free plan supports one email account, up to 10,000 messages, a monthly processing quota, batch cleanup, and per-message unsubscribe. Chuck Pro costs $5.99 a month and adds unlimited accounts and processing, global unsubscribe, AI cleanup suggestions, custom signatures, sender blocking, folder cleanup, advanced filters, and smart notifications.
