What Chato.pro is (and is not)
Chato.pro is a web-based WhatsApp inbox. It is designed for teams that need many WhatsApp numbers, or one number used by several people, without setting up the Meta Cloud API. It is not an official WhatsApp Business API product. Linking works like WhatsApp Web: a QR code, then a live session tied to the phone.
1. Sign in to Chato.pro
Open chato.pro in a browser and sign in with Google. That Chato account is the workspace. To let someone else reply, share a session to their Google email. There is no roles matrix and no per-chat assignment.
2. Connect a WhatsApp number with a QR code
Chato shows a QR code for a new session. On the phone that owns that WhatsApp number, open WhatsApp and use Linked devices (the same flow as WhatsApp Web). Scan the code. The phone must stay online, as with WhatsApp Web.
3. Read and reply in the web inbox
Chats for that number appear in the Chato dashboard. You can search, send messages, and keep several numbers in one sidebar if you added more than one session.
4. Either add more numbers, or share the same login
One person can connect extra WhatsApp numbers (each is a paid session after trial). The owner can also share one session to other Google emails, with view-only or view-and-send access. The customer still messages a single WhatsApp line.
5. Optional: turn on the AI chatbot for a session
On the Standard plan, each connected account can use the included AI chatbot. You train it with your own knowledge so common questions get a first reply without a human on every message.
Trial limits
The free trial lasts 7 days, needs no card, and includes 1 WhatsApp session. To keep that number after the trial, or to add more numbers, you subscribe. Extra numbers are €5 per account per month.
