Best AI Story Writer

Updated 8 November 2026

Best AI story writer

The best AI story writer depends on what you want from it: help writing your own story, or a story written for you. For your own stories, our pick is Feldar, which we make; it drafts from your scene plan and every suggestion waits for your yes. For a story written for you, try NovelAI or a free chatbot.

Two kinds of AI story writer

Before comparing tools, decide which of these you want. Most disappointment with AI story writers comes from picking the wrong kind.

Writing partners

You write the story. The AI suggests, continues a paragraph or rewrites a passage when you ask, and you decide what stays. The story is yours, and so is the work. Feldar, Sudowrite and Novelcrafter are built this way.

Story generators

You write a prompt and the AI writes the story. Quick and often fun. Without strong direction, the stories drift toward familiar shapes and phrases. NovelAI, Squibler, ChatGPT and Claude work best this way.

How to brief an AI story writer

Whatever tool you use, a story is only as specific as its brief. Ask for "a mystery story" and you get the most likely mystery story. Give the AI the things a story is made of instead. Here is a brief we wrote, with the working parts marked:

Write the opening scene of a literary mystery, about 1,200 words, in close third person, past tense. Nell, 34, a schoolteacher, has come home to her father's orchard in Herefordshire in the winter of 1958 for his funeral. She wants to sell the farm and be gone by Sunday. Her flaw: she would rather not know things. In the bottom drawer of his bureau she finds a ledger with the initials M.P. and a payment of two pounds every month for twenty years. End on her deciding not to tell her brother. Avoid opening on the weather.

  • Genre and length set the shape and the pace.
  • Point of view and tense stop the AI choosing for you halfway through.
  • A character with a want and a flaw gives the scene something to push against.
  • A specific place and time is the quickest cure for generic prose.
  • The discovery or turn is the event the scene exists for.
  • An ending beat keeps the scene from wandering or wrapping up too neatly.
  • What to avoid removes the habits you are tired of reading.

In a writing app with story memory you set most of this up once instead of retyping it. In Feldar, Nell and the orchard go on Canvas cards, the beats go in the chapter's scene list, and a sample of your prose sets the style, so each request can be short.

Feldar with an empty chapter called Hard Frost and a Scenes panel listing generated scenes, each with a title and a short description.

Scenes generated for an empty chapter in Feldar. You edit the plan, then write from it yourself or ask Feldar to draft it.

Each story writer, reviewed

What it is like to write a story with each one, and the catch.

01Feldar Ours

Best for writing your own stories from a scene plan, with AI you approve

Feldar is the writing app we make. A story starts as a plan: describe what happens next and Feldar suggests a list of scenes, which you rewrite, reorder or delete. Then you write, with help where you want it. Continue from here adds text at your cursor in blue, with Accept, Revise and Dismiss beside it. Draft Page writes a chapter from its scenes at the length you set. Select any passage to tighten it, deepen it or raise the tension, and see each change marked before you apply it.

Characters, places and objects live on Canvas cards beside the story, so the AI knows them every time you ask. When the draft is done, Lens personas read it and react, and five Checks look for slips in grammar, clarity, word choice, dialogue and point of view.

Good
The story stays yours: AI text is marked until you accept it. Planning and story memory you can see and edit. GPT-6 and Claude 5.5 models. Feldar does not train AI models on your writing.
Watch out
It will not write a whole story from one prompt for you; it is built for writers. Web and Mac only, no offline mode, no phone app. English only. AI uses credits.
Price
Starter free with 500 credits, no card. Core $20 a month or $180 a year. Pro $40 or $400. Ultra $200 or $2,220.

Try Feldar freeStarter plan: 500 credits, no card needed

02NovelAI

Best for generating stories you steer as they go

NovelAI is the most enjoyable pure story generator here. Write an opening, let it continue, nudge it, let it continue again. A Lorebook keeps world details in play, a text adventure mode turns the story into a game, and image generation is included. Story generation runs on GLM 4.6, with NovelAI's own models on the top tier.

Good
Stories are encrypted end to end and NovelAI says it cannot read them. Unlimited text generation on paid tiers.
Watch out
No chapters, outlining or book export. The biggest context, which helps long stories, is on the top tier.
Price
Tablet $10, Scroll $15, Opus $25, each for 30 days. 50 free text generations.

Official site: novelai.net

03Sudowrite

Best for drafting fiction fast with fiction-tuned models

Sudowrite sits between partner and generator: it works on your draft, but it is happy to write a lot of it. Write, Rewrite, Describe, Expand and Brainstorm cover most of what a story needs, its Story Bible keeps characters and outline in view, and its own models, Muse and Ballad, are tuned for fiction.

Good
Fiction-first tools and models. iOS and Android apps. A large community. It says it does not train on your writing.
Watch out
Credits run down with heavy use. The pricing page defaults to yearly billing.
Price
From $10 a month billed yearly, or $19 monthly. Free trial, no card.

Official site: sudowrite.com

04Claude

Best free option for short stories and ideas

Anthropic's Claude writes a decent short story from a good brief, and it is better still as a reader: paste in your scene and ask what is not working. For anything long you will be copying and pasting, and it only knows what is in the current conversation.

Good
Free plan. Thoughtful feedback. Apps on desktop and mobile.
Watch out
No story structure or memory between chats. Anthropic uses consumer chats for training if you allow it, if a chat is flagged for safety review, or if you opt in.
Price
Free. Pro $20 a month, or $17 billed yearly.

Official site: claude.com

05ChatGPT

Best free option for quick stories, prompts and ideas

OpenAI's ChatGPT will write a bedtime story, a ghost story or ten story ideas in seconds. It is the easiest place to start, and the brief above works well in it.

Good
Fast, free, everywhere. A low-cost Go plan.
Watch out
Outside any manuscript, so long stories are hard to keep consistent. On individual plans OpenAI may train on your conversations unless you opt out.
Price
Free. Go $8 a month, Plus $20.

Official site: openai.com

06Squibler

Best for generating a book-length draft

Squibler generates books and screenplays, and its site advertises a full 200 to 300 page book from your idea, with an editor to work on the result. It is the right tool if you want the most automation; you will still have a long revision ahead.

Good
A free plan with 500 AI credits every month. Unlimited AI credits on Pro. You keep ownership of what you create.
Watch out
Export needs a paid plan. We found no training statement in the pages we read.
Price
Plus $29.99 a month or $15.83 billed yearly. Pro $89.99 or $49.17 billed yearly.

Official site: squibler.io

07Novelcrafter

Best for story writing with any AI model you connect

Novelcrafter is a story workspace where you plug in the AI yourself, through OpenRouter, another provider or a local model. Turn scene beats into prose, chat with a scene, and keep your world in a Codex. Setup takes longer than anything else here, and you get more control for it.

Good
Any model, including local models. Editable, visible prompts. A deep Codex.
Watch out
AI is billed separately by your provider. Not for a quick story.
Price
$8, $14 or $20 a month with AI through your own provider; $4 without AI. 21-day trial.

Official site: novelcrafter.com

08Type.ai

Best for a simple AI editor for long stories

Type is a clean document editor with AI built in, made for long-form writing including novels and screenplays. There is no scene planning or story bible, which keeps it simple.

Good
Free credits that never expire. Documents up to 150,000 words. It says it does not train on your data.
Watch out
No story planning tools. Paid credits reset monthly.
Price
Basic $8 a month billed yearly, Pro $16, Max $64.

Official site: type.ai

After the story is written

Three things to check before you share or sell a story written with AI.

  • The tool's terms. Feldar says you own what you write. Sudowrite claims no rights over your input or what it generates for you. Squibler says you keep full ownership. Check any other tool before you publish.
  • The store's rules. Amazon's Kindle Direct Publishing asks you to disclose AI-generated text, images or translations when you publish. AI-assisted work, such as editing or brainstorming on text you wrote, does not need disclosing.
  • Your evidence. If a contest or publisher asks how the story was written, a record of your process answers better than a detector score. Feldar's Writing record keeps one automatically for work written in Feldar.

Questions

What is the best free AI story writer?

For a quick story from a prompt, the free plans of ChatGPT and Claude. For writing your own story with AI help inside a real writing app, Feldar's Starter plan, with 500 credits and no card. Squibler's free plan gives 500 AI credits every month, and NovelAI gives 50 free generations to try.

Can an AI story writer write a whole book?

Some will. Squibler advertises a full-length book from your idea, and NovelAI will keep going as long as you do. Feldar can draft a whole chapter from a scene list. A generated book still needs a writer's revision before most people would want to read it.

Is there an AI story writer with no limits?

NovelAI offers unlimited text generation on all of its paid tiers, and Squibler Pro has unlimited AI credits. Every free plan has limits.

Why do AI stories sound generic?

Usually because the brief is general, so the AI fills the gaps with the most likely choices. Specific names, a real place and time, a character's want and flaw, and an ending beat make the biggest difference. Story memory helps too: tools with character and world notes keep those specifics in every request.

Can I sell a story an AI helped me write?

Often yes, but read the tool's terms and the store's rules. Amazon KDP asks you to disclose AI-generated text when you publish, though not AI-assisted editing or brainstorming. Copyright rules for AI-generated text differ by country.

Will the AI use my story to train its models?

Feldar, Sudowrite, Novelcrafter and Type.ai say they do not, and NovelAI encrypts stories end to end. On consumer plans, OpenAI may train on ChatGPT conversations unless you opt out, and Anthropic trains on Claude chats if you allow it. We found no statement from Squibler.
