The world's first voice-activated recipe book giving budding chefs access to millions of online recipes has been created.

The purpose-built smart tablet dubbed 'Nana' has a huge bank of more than 360,000 in-built dishes with nutritional analysis, estimated shopping costs and health scores.

Its inventors were inspired by their own grandmother to create the £185 tool which uses Artificial Intelligence (AI) to find recipes, create shopping lists and even put together diet plans.
