Rachel Duffy was so good at tricking fellow contestants on The Traitors that she has inspired an AI alter ego which phones pubs to check the price of their pints.
A US engineer, who is a fan of the TV show, has used artificial intelligence to create a "voice agent" with a Northern Ireland accent, which he named 'Rachel'.
On St Patrick's Day weekend AI Rachel called more than 3,000 bars across the island of Ireland asking how much they charge for a Guinness.
Matt Cortland said the cost "varies wildly" from pub to pub and he wanted to create an online price comparison site to promote good value.
He explained he needed an AI voice agent which could interact naturally with pub staff and convince them to answer questions.
