Money Saving Expert is a well-known service for, well, saving money. They have now developed an AI system that will answer your questions by searching the whole MSE database. It’s currently available on the MSE app for Android and iOS.

Go to the speech bubble at the bottom-right and type your question. The AI will respond and you can ask follow-up questions. It doesn’t give product recommendations, so go for ‘How do I’ sort of questions.
