By creative form
- Literary fiction: Claude Sonnet 4.6. Best at restrained, character-led prose. Specific instruction-following on POV and tense.
- Genre fiction (thriller, romance, sci-fi): Sudowrite. Novelist-tuned UX with Story Bible, Beat Sheet, Brainstorm tools.
- Screenwriting: ChatGPT Plus or Claude. Both follow industry-format constraints reliably with a system prompt example.
- Poetry: Claude. Less prone to greeting-card cadences; better at formal constraint following.
- Worldbuilding / D&D campaigns: Claude (1M context fits a whole setting bible) + custom GPT for in-character interaction.
- Game writing / interactive fiction: Inkle’s tools or Claude with a state-tracking system prompt.
- Children’s books / picture books: ChatGPT (text) + DALL-E or Midjourney (illustrations).
The fiction-specific tools
- Sudowrite ($10-29/mo) — fiction-specific, includes story bible, canvas, and beat-sheet workflows. The most-used novelist tool in 2026.
- NovelCrafter ($14/mo) — codex + chapter view + AI assistance. Strong for plotters.
- Plottr — outlining and structure, with AI-assisted scene cards.
- Lex — distraction-free writing with AI in the margin.
What to avoid
- Letting the AI write whole scenes from a one-line prompt. Outputs are competent but generic.
- Skipping the human voice pass. AI prose is fluent but rhythmically predictable.
- Using AI for the climax. Save the most emotionally loaded scenes for your own pen.
The two pricing paths
- $20/mo: Claude Pro alone. Sufficient for most literary writing.
- $30-50/mo: Claude Pro + Sudowrite. Sudowrite’s UX adds enough novelist-specific value to justify both.
