Google has started rolling out its AI chatbot Bard, but it is only available to certain users and they have to be over the age of 18.

Unlike its viral rival ChatGPT, it can access up-to-date information from the internet and has a “Google it” button which accesses search.

It also namechecks its sources for facts, such as Wikipedia.

But Google warned Bard would have “limitations” and said it might share misinformation and display bias.

This is because it “learns” from real-world information, in which those biases currently exist – meaning it is possible for stereotypes and false information to show up in its responses.
