"AI story generator" covers very different tools. Some help novelists draft and revise. Some let you play a story as it's generated. Some are general chatbots you can ask for a story. This guide compares six options by what they're built for, using each company's own published descriptions, so you can pick the right kind of tool before you pick a brand.
Product descriptions reviewed October 9, 2026, from the linked official pages. Features and prices change, so check the current page before you sign up. This is a summary of published information, not a hands-on test.

AI story generators for writing
Sudowrite
Sudowrite describes itself as an AI writing partner built for novelists. Its homepage lists tools including Write (suggests the next few hundred words in your voice), Describe, Expand, Rewrite, Feedback, Brainstorm, a Story Bible that takes a project from idea to outline to chapters, and Canvas for plotting. It names its own fiction-focused model, Muse.
- Free option: a free trial, then $10/month according to its homepage.
- Best for: novelists who want help drafting and revising a long manuscript.
Squibler
Squibler presents itself as an AI book and novel writer. You chat with AI to write books, novels and screenplays. Its homepage describes generating a chaptered first draft from a concept and genre, outlining structure and pacing, tracking characters and settings, revising text with an "AI Smart Writer," and generating visuals from passages.
- Free option: a free limited tier, with paid Plus and Pro plans.
- Best for: writers who want a fast first draft or a structured outline.
AI story generators for playing a story
AI Dungeon
AI Dungeon describes itself as a free AI text adventure game. You choose a scenario (fantasy, post-apocalyptic, custom or community-made) and type what you do; the AI writes what happens next. According to Wikipedia, it was created by Nick Walton in 2019 and is developed by Latitude, with premium tiers offering more advanced models.
- Free option: free to play, on the web and in an app.
- Best for: open-ended adventures where anything can happen.
Character.AI Stories
Character.AI is best known for character chat, but in November 2025 it announced Stories, a format where you choose characters, set a genre and premise, and guide a branching story through choices. Note that Character.AI announced in October 2025 that it would stop users under 18 from chatting with characters. Read our Character.AI safety guide for details.
- Best for: people who already use Character.AI and want something more structured than chat.
General AI chatbots as story generators
ChatGPT (OpenAI), Claude (Anthropic) and Gemini (Google) are general-purpose AI assistants. None is built specifically for fiction, but each can write a story, suggest plot ideas, outline chapters or continue a scene when you ask. Check each one's site for current free and paid options.
- Best for: quick stories, brainstorming and outlines, if you don't mind writing your own instructions.
- Tip: the more specific your request, the better the story. Give the genre, the characters, the setting, the tone and the length.
Where Be My Story fits
Be My Story isn't a blank-page generator. It's a mobile app with ten curated romance and drama story experiences. You choose one, write your character's dialogue or actions in your own words, and read AI-generated scene replies. With an account you can save separate stories. If you'd rather step into a story than build one from scratch, it's made for that. It's available on Google Play and the App Store.
Free AI story generators: what "free" usually means
- Free trial: full features for a limited time, then a subscription.
- Free tier: a permanent free plan with limits on usage, model quality or features.
- Ad-supported: free, with ads.
Before you commit a long project to any tool, check its terms on who owns what you write, how your text is stored, and whether it's used to train models.
How to get better stories from any AI story generator
- Start with a situation, not a topic. "A story about a dragon" is a topic. "A dragon applies for a job as a museum exhibit" is a situation. Our 120 writing prompts and story ideas are full of them.
- Name what the main character wants. AI writes more focused scenes when the goal is clear.
- Set the tone and length. "Wry, 500 words, ends on a twist" beats "write a story."
- Edit, don't just accept. Keep the lines you like, rewrite the rest, and ask for alternatives.
- For interactive tools, give your character one intention per turn. See our guide to AI roleplay.
