What WhatSync does
WhatsApp for the AI agents you already use.
Your WhatsApp in your AI apps
Link your number and ask ChatGPT, Claude, Cursor or Codex about your chats: who is waiting on you, what a group decided, what a customer asked for. Your AI can draft and send replies you approve.
The WhatsApp Business API
Connect a number through Meta to send templates and campaigns to customers who opted in, from your AI app or your own code.
A CLI and an API for builders
Agents that run terminal commands use npx whatsync. Your own code uses the REST API and webhooks.
Free WhatsApp tools
Link and QR code generators, a text formatter, a template builder, cost calculators and more. They run in your browser with no account.
