I had an idea for a fun little side project about a year and a half ago, thought it would take me a few weeks to a month using AI to get done... Needless to say, it didn't go as planned and 6 months later ended up finishing a full book. Since then I have two books half written and just finished a Novella back in October.
Big thanks to and his vids on writing with AI and reviews and suggestions about the best tools to use.
