ChatInbox organizes your inbox by people. Each person you email gets one conversation that holds everything you've exchanged: every subject, every reply, every attachment. When a new email arrives, its person moves to the top, with your whole history right there. Newsletters, receipts and alerts file themselves into Feeds, so mail from people is never buried. ORGANIZED BY PEOPLE Your list shows people, not a pile of messages. Tap a person to see every email between you, across every subject, in one place. Read it as cards by thread or as a chat with your replies on the right. Put a company or a team together in one row. Many people use ChatInbox as a simple CRM: every client's emails, files and follow-ups in one place. PEOPLE FIRST, FEEDS SEPARATE Newsletters, receipts and notifications go to Feeds automatically. Clear a sender in one go: Mark All as Read, Archive All, or Unsubscribe & Delete All. TODAY'S INBOX, DONE FAST Triage sorts today's mail into a plan: what needs a reply, what can be archived, codes you no longer need. Apply it at once, with Undo. AI THAT STAYS ON YOUR DEVICE With Apple Intelligence, ChatInbox shows what people are waiting on you for, lists the questions in an email and drafts your answer, catches you up on what's new from people, and answers questions about your mail with the email it came from. Translate an email in place, on your device. FIND ANYTHING Search reads the words inside your emails and even inside PDFs and other attachments. Or open a person, and everything with them is already there. YOUR ACCOUNTS, YOUR DEVICES Gmail, Outlook, iCloud, Yahoo and any IMAP account. Type your address and ChatInbox finds the settings. Works on iPhone, iPad and Mac, and one purchase covers all three. CALENDAR, TO-DOS AND TAGS See your week beside your mail, turn an email into an event or a to-do, and tag conversations to track them on a board.
