This app gets the top HackerNews article (from https://news.ycombinator.com/best) once a day and writes a 500-word blog post about it using ChatGPT. The articles are stored in S3 and published on this Python web app.
It has been entirely built by me chatting to ChatGPT (GPT-4) and copying and pasting responses into text files. I did not write a single line of Python or HTML.
It's running at https://chatgpt-chronicles.herokuapp.com. Records of the chats used to create it can be downloaded at https://chatgpt-chronicles.herokuapp.com/about.
