| Long coherent fiction | Claude |
| Brainstorming and plotting | ChatGPT |

Bottom line
AI is a co-writer, not a ghostwriter. Use Claude for deep drafting, ChatGPT to break through blank-page moments, and Jasper when a story has to move product. Keep your own voice in the driver's seat and edit heavily — the best AI-assisted stories still read as unmistakably human.
