Questions business owners ask
How do I install it?
One line of code before the end of your page. Two minutes, no technical skill: this page shows where to paste it for your tool. To remove it, delete the line.
Which languages does Emma answer in?
The visitor’s language: French, German, English, Italian and others. Your website stays in the language you chose.
Where does the data go?
Conversations are hosted in Switzerland and kept only as long as the service needs them, with no advertising. Nothing is sold. Details on our Privacy page.
Is WhatsApp required?
Yes: that is where Emma talks to you, and where your customers continue the conversation from their phone. On a computer they can also chat directly in the page.
What happens beyond 100 messages?
On Light, beyond 100 customer messages in a month, Emma tells the customer how to reach you directly. On Pro, messages are unlimited (owner and customers).

Can Emma get it wrong?
