Talk to the people who build WhatSync

Setup, billing, privacy or a feature you need. You reach the builders directly.

Email

Best for setup, billing, privacy and anything that needs a written answer.

Please leave out passwords, QR codes, sign-in codes, API keys and the contents of customer chats. The page you were on, roughly when it happened, and a phone number with some digits hidden are usually enough.

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.
