Brother Claude has been helping me build the Deepest Turtle website, which accompanies my book "An Engineer's Search for Meaning".

For example, it helped me create an interactive explorer for the book, which gives you a quick tour of the main ideas.

Here is the link: Interactive Book Explorer.

Most of the visual design and code is by Claude (with many prompts and course corrections from me). It also wrote the first draft of the text after reading the entire book in a few seconds. I had to edit it quite a lot though, not because it was "wrong" per se, but more because some important ideas were omitted, some of the emphasis was wrong, and some of the wording was not right. Still, the first draft was a major help.

Just to give you a quick intro, the book is about taking an engineering approach to probably the most badly needed "product / service" in the world, helping people find meaning, purpose and hope in life. (It's a little shame that scientists and engineers have shied away from this important topic. It's time we took up the challenge.)
