In a Which? Money podcast episode, senior data journalist Josh Wilson shared findings from his investigation into how accurately chatbots answer personal finance questions. He tested five chatbots—ChatGPT, Google Gemini, Google’s AI Overviews in standard Google searches, Microsoft Copilot and Perplexity—by asking them 15 common personal finance questions based on search trends. The questions covered pensions, debt, investing, saving, insurance, equity release, tax and mortgages. Which? money experts rated and reviewed every response, and the episode also offered advice on using chatbots and warned about the risks of relying on them. The podcast is part of Which?'s always-on output, with Which? Money episodes released on Fridays.
