That's a really interesting question! I think one key to making AI text sound natural is avoiding overly formal language. People often use contractions, slang, and idioms in everyday conversation, and AI often struggles with these. Also, injecting a bit of personality and humor can go a long way. It reminds me of some of the characters in Poptropica – they were so memorable because they felt genuinely quirky. Thinking about how human writers create distinct voices could be a great strategy for AI too!
