Relationships are hard to read from inside the conversation. If-Reply turns LINE, Instagram, WhatsApp , WeChat, and KakaoTalk chat history into practical next steps: see conversation patterns and turning points, get three next-message options with example replies, rewrite a past message with If Reply to explore an AI-predicted alternative, and talk with Ifre(AI-character) for supportive coaching. Basic analysis runs in your browser; chat history and results stay off If-Reply servers.
