Despite the realistic chance that seanblue will immediately tell me how useless my tool is , I’d like to mention that I once wrote a generator script for book club threads (and I’m using it ever since for all my book clubs except the most recent very exotic ones like Flesh&Blood and 糞尿èš): Book Club Weekly Thread Forum Post Generator(TM)
Disclaimer: The github repo is not exactly up-to-date, and I recently caved in and converted the code to TypeScript which means that running one more command is necessary in the setup process. If you are interested, I can update the repo to the latest version.
