So, I tried using Google ~~Bard~~ Gemini to help write one-line Character Background descriptions for a 5e supplement I'm trying to write. I specifically feed it the longform descriptions and features I've already written and ask it to summarize. The output I get is so foreign and detached from my "voice," it's totally unusable.
Even when giving it more than you want to get out, it can't produce acceptable results. I can only imagine the drek this lady is being inundated with, and it makes me sad.
The only success I've had so far is telling it, "pluralize X in this paragraph," in places where I wrote something like, "A Painter paints for a living," and want it to be, "Painters paint for a living." (I'm pretty sure Microsoft Word could do this shit in the 90s.)
