Which? study of ChatGPT, Copilot and others uncovers incorrect and misleading tips on investments, tax and insurance

Artificial intelligence chatbots are giving inaccurate money tips, offering British consumers misleading tax advice and suggesting they buy unnecessary travel insurance, research has revealed.

Tests on the most popular chatbots found Microsoft’s Copilot and ChatGPT advised breaking HMRC investment limits on Isas; ChatGPT wrongly said it was mandatory to have travel insurance to visit most EU countries; and Meta’s AI gave incorrect information about how to claim compensation for delayed flights.

Google’s Gemini advised withholding money from a builder if a job went wrong, a move that the consumer organisation Which? said risked exposing the consumer to a claim of breach of contract.

Which? said its research, conducted by putting 40 questions to the rival AI tools, “uncovered far too many inaccuracies and misleading statements for comfort, especially when leaning on AI for important issues like financial or legal queries”.
