The 10 best AI story generators
1. Sudowrite: Best for fiction writers
- Starting price: $10/month billed yearly, $19 monthly (Hobby and Student)
- Free plan: Trial credits
- Best for: Novels, short stories, serial fiction
Sudowrite is built for fiction. Its Story Engine helps you move from a premise to an outline, chapters and scenes, and tools like Describe, Rewrite and Brainstorm help with sensory detail, alternate phrasing and plot twists. Plans scale from Hobby and Student (225,000 credits a month) to Professional ($29 monthly, $22 yearly, 1 million credits) and Max ($59 monthly, $44 yearly). Prices here come from a third-party tracker, so confirm on Sudowrite’s site.
2. ChatGPT: Best all-rounder
- Starting price: Free; Plus $20/month
- Free plan: Yes
- Best for: Any genre, plus illustrations with ChatGPT Images
ChatGPT can brainstorm premises, build characters, outline, draft scenes and then illustrate them with ChatGPT Images 2.5, which keeps characters more consistent across edits. Use Projects to keep your story bible (characters, places, rules) in one place so every chapter stays consistent. See how to use ChatGPT.
3. Claude: Best for natural prose
- Starting price: Free; Pro $20/month
- Free plan: Yes
- Best for: Literary fiction, editing and long manuscripts
Claude’s writing tends to sound the most human, and its large context window lets you paste whole chapters for feedback on pacing, voice and continuity. Many authors use Claude as an editor rather than a ghostwriter. Our Claude writing prompts include story editing templates.
4. Gemini Storybook: Best for kids’ illustrated stories
- Starting price: Free in the Gemini app
- Free plan: Yes
- Best for: Parents, teachers, bedtime stories
Gemini’s Storybook experiment creates a 10-page illustrated story from your idea, with art styles such as claymation or anime, or even your child’s own drawing style, and it can read the story aloud. It works in all languages Gemini supports, which makes it great for Hindi or regional language stories. It launched as a Gem in 2025; with Gems moving to Skills, look for it in the Gemini app’s tools. See Gemini Skills explained.
5. NovelAI: Best for long interactive fiction
- Starting price: Tablet $10/month; Scroll $15; Opus $25
- Free plan: Paper trial with 50 text generations
- Best for: Adult writers who want a flexible co-writer
NovelAI continues your story in your style and remembers more of it on higher tiers; Opus has the largest context, up to 28,672 tokens, plus image generation allowances. It is aimed at adults and allows mature fiction, so it is not suitable for children.
6. Novelcrafter: Best for planning big projects
- Starting price: Low-cost monthly plans
- Free plan: Trial
- Best for: Plotters who want a codex and outline
Novelcrafter is a writing workspace with a codex for characters and locations, a scene-by-scene outline and AI help that can use models you connect with your own API key. It suits writers who like to control their tools and costs.
7. Squibler: Best for fast first drafts
- Starting price: Monthly plans
- Free plan: Limited
- Best for: Quick drafts, screenplays and short stories
Squibler generates whole story drafts from a short prompt and offers templates for novels and scripts. It is useful when you want a rough draft quickly and plan to rewrite heavily.
8. AI Dungeon: Best for story games
- Starting price: Free
- Free plan: Yes
- Best for: Choose-your-own-adventure play (adults)
AI Dungeon turns stories into games where you type what your character does and the AI narrates what happens. It is fun for brainstorming plots, but content can be mature, so it is for adults.
9. Canva: Best for designing story books
- Starting price: Free; Canva Pro for more AI
- Free plan: Yes
- Best for: Picture books, classroom stories, posters
Canva’s Magic Studio can draft text and generate images, and its book templates make it easy to lay out a finished picture book to print or share. Pair it with ChatGPT or Gemini for the writing. Read our Canva Magic Studio review.
10. Microsoft Copilot: Best free option on Windows
- Starting price: Free
- Free plan: Yes
- Best for: Quick stories and pictures without signing up for another tool
Free Copilot can write short stories and create matching images with daily limits, and it is built into Windows and Edge. It is a simple starting point for students and families.

AI story generators for kids: safety tips for parents and teachers
- Use tools designed for general audiences, such as Gemini Storybook or ChatGPT, and avoid adult fiction tools like NovelAI and AI Dungeon.
- Check each service’s minimum age; many require users to be 13 or older, and some 18.
- Read stories before sharing them with young children, and adjust anything scary or confusing.
- Use AI to spark creativity: let kids invent the characters and choose what happens next.
Teachers can find classroom ideas in AI for teachers, and students in our list of AI tools for students.
Can you publish AI-generated stories?
You can publish stories you wrote with AI help, but rules vary. In the US, the Copyright Office does not protect purely AI-generated material; your human contributions such as selection, arrangement and substantial rewriting can be protected. Some publishers and platforms ask you to disclose AI use. The safest path is to use AI for brainstorming and drafts, then rewrite substantially in your own voice. Our guide Can you copyright AI content? explains the rules in the US and India.
Tip: keep a short log of how you used AI on each project. It helps if a publisher asks, and it shows how much of the work is yours.
How to choose an AI story generator

Frequently asked questions
What is the best AI story generator?
Sudowrite is the best dedicated tool for fiction writers. For most people, ChatGPT and Claude are the best all-round choices because they are free to start and handle any genre. For illustrated children’s stories, Gemini Storybook is the easiest option.
Is there a free AI story generator?
Yes. ChatGPT, Claude, Gemini (including Storybook), Microsoft Copilot and AI Dungeon all have free versions. Sudowrite and NovelAI offer limited trials. Free plans have daily limits, which are usually enough for short stories.
Can AI write a whole book?
AI can draft a whole book, but the result usually needs heavy editing for voice, consistency and originality. The best results come from using AI to outline, draft scenes and give feedback, while you make the creative decisions and rewrite in your own style.
Which AI is best for kids’ stories?
Gemini Storybook creates 10-page illustrated stories with read-aloud audio in many languages, which makes it ideal for children. ChatGPT also writes good kids’ stories and can illustrate them. Avoid adult fiction tools like NovelAI and AI Dungeon for children.
Can I sell a story written with AI?
Generally yes, as long as you follow the platform’s rules and the AI tool’s terms. Purely AI-generated text may not be protected by copyright, so add substantial human writing and editing, and disclose AI use where a publisher or platform requires it.
Our recommendation
Start with a free tool you already have, such as ChatGPT, Claude or Gemini, and try the prompts above on a short story. If you are writing seriously, test Sudowrite’s trial; if you are making stories for children, try Gemini Storybook.
