What can AI do for writers?
AI for writers means using a language model as a writing partner: it brainstorms ideas, outlines plots, drafts scenes in a voice you describe, checks continuity across chapters and gives line-level feedback. You stay the author; the model suggests and you choose. On NanoGPT you can use a different model for each of those jobs.
How it works
- Step 1
Paste your scene or outline
Start with what you have: a chapter, a premise or a list of plot points.
- Step 2
Ask two models for notes
Send the same request to several models side by side and compare their ideas.
- Step 3
Keep what works
Take the lines you like and write the rest yourself. Your drafts stay on your device.
Which model for which writing task
Picked from NanoGPT’s rankings; each row says which one. The picks change when a better model ships.
| Task | Model | Why |
|---|---|---|
| Brainstorming |  GLM 5.3 | The highest-ranked writer that costs $5 or less per 1M output tokens, so 50 ideas at a time stay cheap. |
| Outlining and structure |  Claude Opus 5.5 | Highest-ranked on NanoGPT in the combined benchmark, which rewards reasoning and planning. |
| Drafting fiction | Claude Opus 5.5 | Highest-ranked on NanoGPT in the creative writing blend (LMArena and EQ-Bench). |
| Dialogue | Claude Opus 5 | Highest-ranked on NanoGPT in the roleplay benchmark, which rewards distinct voices and emotional intelligence. |
| Editing and line polish |  GPT 6 Astra | #4 in creative writing, from a different lab than the drafting pick: a second ear for your prose. |
| Whole-manuscript feedback | GPT 6 Astra | Reads 1.05M tokens, about 790,000 words, in one go. |
| Dark themes |  Abliterated Model Large V2 | Uncensored, so crime, horror and mature scenes get written instead of refused. |

Work with the whole manuscript
Long-context models can read a full chapter, or a whole book, in one message. Paste it in and ask for a continuity check: names, timelines, who knows what when, and threads you dropped.
| Model | Context | Roughly |
|---|---|---|
| Claude Opus 5.5 | 1M tokens | about 750,000 words |
| Claude Fable 5.1 | 1M tokens | about 750,000 words |
| GPT 6 Astra | 1.05M tokens | about 790,000 words |
| GPT 6 Sol | 1.05M tokens | about 790,000 words |
| Gemini 4 Argon | 1.05M tokens | about 790,000 words |
Dark themes without the refusals
Crime, horror, war and morally gray characters trip the filters of mainstream models. Switch to an uncensored model for those scenes and back again for the rest, in the same chat.
Prompt starters
Copy one into the chat and paste your text after it.
Critique this scene’s pacing
“Here is a scene from my novel. Tell me where the pacing drags or rushes, quote the exact lines, and suggest one fix for each. Don’t rewrite the whole scene.”
Rewrite in a voice
“Rewrite this paragraph in the voice of a hard-boiled 1940s detective narrator. Keep every plot detail; change only the voice.”
Find plot holes
“Here is my chapter outline. List every plot hole, unexplained motive or timeline problem you can find, most serious first.”
Give me 10 titles
“Here is my book’s premise. Give me 10 title ideas in different styles, from literary to commercial, with one line on why each works.”

Frequently asked questions
Which AI is best for fiction?
Right now Claude Opus 5.5 is the highest-ranked model on NanoGPT in its creative writing ranking, a blend of LMArena Creative Writing and EQ-Bench’s creative and long-form writing tests. Taste matters, so send the same scene to two or three models and keep the voice you like. See the writing ranking.
Will AI write my book for me?
It can draft, but the books that work still come from a writer making the choices. Most authors use AI to brainstorm, outline, unblock a scene, check continuity and polish lines, and write the parts that matter themselves.
Who owns the text I write with it?
You do. NanoGPT’s terms say you keep ownership of what you put in and own what the model writes for you, subject to the law where you live. Read the terms.
Are my drafts private?
Your chats, and the drafts in them, are stored on your device, and NanoGPT doesn’t log your prompts or replies. The model provider sees what you send to answer it; turn on Zero Data Retention routing in Settings to use only providers that say they keep no copy. What is stored where.
Can I use it for mature fiction?
Yes. Adults can use uncensored models for crime, horror, violence and mature themes that mainstream models refuse. Illegal content is never allowed. Uncensored models.
How much does a novel draft cost?
A 90,000-word draft written chapter by chapter is roughly 120,000 tokens written and 600,000 tokens of context sent. At today’s prices that’s about $4.80 on Claude Opus 5.5 or $0.49 on GLM 5.3, with no subscription. Pro ($12 a month) covers open models within its weekly allowance.
