How it works
A chatbot writes words that sound right, and it is good at sounding sure. It picks words that fit, using patterns from lots of writing.
When it does not know, it may still fill the gap with good-sounding words. It is not lying on purpose, it just does not always know what is true.
It can make up facts, make up sources such as a book or an expert, and give a different answer each time.
So check a fact in a second source, a place your family trusts. When two good places agree, you can feel more sure.
