Setup
Three things, then it answers.
There is no training, no flow builder, and no decision tree to draw. If you can write down what you already tell people, you can set this up.
Connect a channel
Telegram takes about two minutes and needs no approval. WhatsApp goes through Meta's official connection, which keeps your number working as a normal phone and in your WhatsApp Business app.
Paste in what you already say
Opening hours, prices, where to park, your cancellation policy, the five questions you answer every day. Paste text, upload a document, or point it at a page on your site. It only ever answers from this. Add your services and how long each takes, and it can book them too.
Watch the first few, then stop watching
Everything it sends is in your console. Anything it was unsure about is flagged for you rather than guessed at. Most people stop checking after a week.
What happens to a message
It waits a moment, on purpose.
If you reply yourself from your own phone, it notices and stays quiet. It will not talk over you.
