The Honest Truth About AI + Fiction

After 30 days of testing, here's the reality: AI is a brilliant assistant and a mediocre author.

It shines at the planning โ€” worldbuilding, character profiles, chapter outlines, plot structure. And it's excellent at dialogue and short scenes with the right prompts.

But full-chapter AI prose reads flat after a while. The writers getting the most value use AI to scaffold, then write or heavily rewrite the prose themselves. The best results came from feeding the AI your own writing as a voice reference.

How to Use AI for Your Novel (Workflow)

  1. Worldbuild with AI: Generate premises, magic systems, factions, and lore
  2. Build characters: Core desire, fatal flaw, backstory, voice
  3. Outline scenes: Entering emotion, inciting moment, turning point, exit hook
  4. Draft with AI as scaffolding: Generate a rough scene, then rewrite it in your voice
  5. Edit aggressively: The final voice must be yours โ€” AI output is a starting point, not the finish

Voice โ€” The Hardest Part

The #1 complaint writers have is "AI prose all sounds the same." Our fix: paste 2-3 paragraphs of your own writing into the prompt as a style reference. It outperforms describing your tone with adjectives. Combined with heavy editing, this keeps your voice intact.
