When we click a website link sent on our WhatsApp by tarsinvitations.com, we are directed to another conversation page. The user on the other side greets us with 'Hey there' and goes on to say, 'We, Gaurav and Lavani, are getting engaged and want you to be part of the celebrations'. The next post is a cute selfie of the couple, after which, we are asked to click on either of the two options: 'When is the engagement' or 'Want to see more pics of you guys'. We click the former. What follows is a conversation where we receive the time, venue and dress code of the event, while we send in our RSVP with name and contact number. When we send a nine-digit mobile number by mistake, the reply is: please send a valid number. This may sound like a real-life conversation with the couple, but it's actually a chatbot doing all the work.
