Example
The Second Letter
The letter came on a Tuesday, in the supply boat's canvas bag, between the paraffin order and a seed catalogue nobody had asked for. Agnes knew the handwriting before she knew she knew it. Ten years had not changed the way Ellen crossed her sevens.
She did not open it on the jetty. She carried it up the hundred and twelve steps to the lamp room, set it on the brass rail, and trimmed the wick first, because that was the job, and because her hands needed something to do.
Paste it into a page in Feldar, free with 500 credits and no card, and the plan, the cast and the rest of the book sit beside it.
How the AI story writer works.
1. You give it an idea
A sentence or two about who the story is about and what happens. The more specific, the better the story.
2. It plans and writes
It gives the main character a name and a want, builds to a turn, and finishes with an ending that resolves or lingers on purpose.
3. You make it yours
Read it, keep what surprises you, and rewrite the rest. Try again for a different take on the same idea.
How to write a story with AI, step by step.
- Write the idea as a person and a problem. "A lighthouse keeper receives a letter from her sister, who drowned ten years ago" works because it has someone, something that shouldn't happen, and a question.
- Pick a genre and a tone. Genre sets the furniture (a mystery wants a clue, a romance an obstacle between two people). Tone sets the weather: eerie, cozy, bittersweet. Leave them on Any to let the writer choose.
- Choose the point of view. Third person gives you a little distance and is easiest to edit. First person gives you a voice.
- Start short. About 500 words is a scene with a turn. Ask for 1,000 when you want room for a middle.
- Read it twice. Once as a reader, for what grabbed you. Once as a writer, for what you would change.
- Try again, or change one thing. The same idea with a different tone often shows you what the story is really about.
- Make it yours. Copy it into your own document and rewrite it in your words. The ending is usually the first thing to rework.
A worked example: from an idea to a story you can keep.
An illustration of how a writer might use the tool, written for this page.
Sam has an image and nothing else: a ferry bell that someone rings every night for nobody. He types "A woman rings a ferry bell every night for a brother who never came back", chooses Literary and Bittersweet, and asks for about 500 words.
The first story gives the woman a name, Maren, and builds to a stranger who tells her she has been ringing the bell wrong all these years. The premise turns supernatural. Sam doesn't want a ghost story, but one line catches him: the rope worn smooth by her hands.
He tries again with the tone set to Hopeful. This time a child is waiting on the slipway, and the story ends with the woman ringing the bell for someone else. That is the turn Sam was missing: the ritual stops being about grief when it serves another person.
He keeps neither story. He writes his own, about 300 words, with the worn rope from the first draft and the child from the second, and an ending that is his alone. You can read a version of that story, taken apart beat by beat, in our story writing guide.

What each genre asks of a short story.
Use these when you choose a genre, or when you rewrite the story yourself.
| Genre | The story needs | Watch out for |
|---|---|---|
| Mystery | A question, a clue the reader can see, and an answer that was possible all along | A solution that comes from nowhere |
| Fantasy | One rule of magic or the world that costs something | Explaining the whole world |
| Science fiction | One change to how people live, followed to its human cost | Technology without people |
| Romance | Two people, a reason they can't simply be together, and a turn toward each other | An obstacle that one conversation would fix |
| Horror | A safe place that stops being safe, and a reason the character stays | Showing the monster too early |
| Literary | A small, specific change in how someone sees their life | Nothing happening on the page |
| Fairy tale | A clear rule, a test, and a reward or punishment that fits | Modern irony that breaks the spell |
How to get a better story.
Name the want
"A diver who wants to find her father's boat" gives the story a spine. "A story about the sea" does not.
Add one strange detail
A letter in a freezer, a clock that runs backwards. Specific details give the AI something to build on.
Choose the tone on purpose
The same idea reads very differently as eerie, funny or bittersweet. Try two and compare.
Keep it short first
About 500 words is a scene with a turn. Ask for 1,000 when you want more room for a middle.
Rewrite the ending
AI endings are often the weakest part. Treat yours as a draft and finish the story yourself.
Use it to unstick, not to replace
It is best as a sketch to argue with: what it gets wrong often shows you what your story is.
Honest limits.
Short stories only
It writes one story of up to about 1,000 words. For a book, plan it with the AI book writer.
A general audience
No explicit or hateful content and nothing about real private people. A safety check screens each idea.
Not for contests
Many magazines and contests do not accept AI-written stories. Use it to practise and plan, then write your own.
AI story writer or story generator?
Feldar has both, and they do different jobs.
Use the AI story writer
When you want a whole story to read, written in prose by an AI model from your idea.
Use the story generator
When you want a story start to write yourself: a protagonist, three turns and an ending, made from hand-written parts with no AI. Story generator
When a story wants to be a book.
In Feldar you plan each chapter as scenes, keep your characters and places on a Canvas beside the page, and write with AI help that waits for your OK. See Feldar as novel writing software, or plan the whole book with the AI book writer.
Questions about the AI story writer
Is the AI story writer free?
Yes. You can write 10 stories a day with no sign-up and no card.
Do you keep my ideas or stories?
No. Your idea is sent to the AI model to write the story and is not saved or logged by Feldar. The story exists only on your screen until you copy it.
Which AI writes the stories?
Kimi K2.6, an open model by Moonshot AI, running on Cloudflare Workers AI, with Google's Gemma taking over on very busy days.
Can I publish a story it writes?
You can use it, but most magazines and contests have rules about AI-written work, and many do not accept it. Use it as a draft and make the final story your own.
Can it write for children?
Yes. Choose Bedtime story or Fairy tale. Every story is kept suitable for a general audience, and a safety check screens each idea.
Why did it change my idea?
If an idea asks for explicit or harmful content, the writer turns it into a suitable story on a nearby theme, or declines.
Is this the same as an AI story generator?
Yes, it generates a complete story from your idea. If you want ingredients to write the story yourself instead, the free story generator gives you a protagonist, three turns and an ending with no AI.
How long can the story be?
About 500 or about 1,000 words. For anything longer, plan it as a book.
