WhatSync connects WhatsApp to ChatGPT, Claude, and other AI agents, using personal numbers or the WhatsApp Business API. It offers two connection methods—personal WhatsApp linked via device screen, and the official WhatsApp Business API with Meta‑approved templates. Users can filter chats, control data sharing, and the service respects privacy, not selling message contents. Built by Appstronauts, it integrates AI assistants to read, search, and draft replies, with optional voice note transcription on Pro plans.
