Mind if I ask how you’re doing this? I have uploaded short stories of <40,000 words in .txt format and when I ask questions like “How many chapters are there?” or “What is the last sentence in the story?” it gets it wrong. If I paste a chapter or two at a time then ask, it works better, but that’s tedious…
