Everything in the lessons comes from a source. Here they all are in one place, so you can check them yourself.
How we choose sources. For how AI works: courses from universities, research and the documentation of the makers. For tools: the maker's own site, on the date shown. For rules and safety: the government and organisations such as the fraud helpline. Tools change fast, so we check every source again within six months, and within three months for tools.
