In a unique exercise combining artificial intelligence and pub culture, an AI voice agent named Rachel made phone calls to over 3,000 pubs across Ireland during Paddy’s weekend in 2026. This initiative, led by Matt Cortland, aimed to gather data on the cost of a pint of Guinness, uncovering varying price points across the country. The project highlights the intersection of AI technology and everyday aspects of life, emphasizing the potential benefits of data collection in pricing transparency. Notably, the use of an AI voice agent in this context raises questions about the evolving role of technology in traditional settings.
Back in the 2000s, Ireland’s Central Statistics Office had provided regular updates on pint prices, but this ceased in 2011. Over a decade later, Cortland’s Guinndex project seeks to fill this void. Historically, Guinness prices have seen substantial hikes, with prices climbing nearly 50% in the absence of official tracking. The contrasting past and present scenarios spotlight the significance of the Guinndex in bridging this information gap and underscoring the effects of inflation on consumer purchases.
How did Matt Cortland develop this unique project?
Matt Cortland, an AI engineer based in London, architected the Guinndex project. With a background involving pub ownership and AI development, Cortland brings a distinctive perspective to the table. His hands-on experience in both fields equipped him with the understanding needed to design Rachel, an AI agent capable of engaging pub staff convincingly. The project’s development also drew upon technologies such as ElevenLabs’ conversational AI platform and Twilio for effective voice synthesis and telephony, respectively.
What was the response from pub staff?
During the phone calls, most pub staff interacted with Rachel without realizing she was an AI. The exchanges ranged from playful banter to incredulous curiosity, reflecting both the novelty of the technology and its ability to blend into everyday interactions seamlessly. Notably, many bar staff appreciated the transparency once they were aware of the project’s intent. According to Cortland, balancing Rachel’s human-like qualities against the AI’s purpose was key, demonstrating the delicate line between technological innovation and public acceptance.
Pubs around Ireland featured a spectrum of reactions, with a few memorable quotes showcasing both humor and warmth. At one pub, bartenders laughed off the AI with offers of free pints, highlighting the friendly spirit that pervades traditional Irish hospitality, even in interactions with machines. Reflecting on these conversations, Cortland acknowledged the cultural adaptations required to optimize Rachel for this particular market, emphasizing the unique challenge of incorporating banter into an AI agent’s capabilities.
For Cortland, the ultimate goal remains data-driven. The Guinndex serves primarily as a repository of pint prices across Ireland, contributing to transparency and potential pricing normalization. This initiative encourages public involvement through a crowdsourced reporting mechanism. By contributing pint prices via the Guinndex website, individuals can actively participate in the data collection process, effectively expanding the reach and accuracy of the dataset. The crowdsourcing aspect not only democratizes data collection but also fosters community engagement.
The Guinndex project signifies a novel application of AI, underscoring its capability to intersect with societal and economic dimensions in tangible ways. As AI technology becomes increasingly pervasive in traditional industries, it accentuates both opportunities for enhancing operational transparency and challenges related to human interaction. For consumers, obtaining a comprehensive dataset of Guinness prices across Ireland offers valuable insights into geographical price disparities and encourages informed purchasing decisions.
