AI Reply Assistant connects your WhatsApp, Telegram, Instagram and Messenger accounts on iPhone and iPad and drafts replies from the actual conversation. Smart Reply gives three drafts you edit and send; nothing goes out without your tap. Summary sorts unread chats into replies needed and FYI. It runs on Apple Intelligence on-device, or Claude with your own key or pay-as-you-go credit, and adds scheduled messages, translation and Apple Shortcuts actions.
