How to continue a story where you left off
Reread the last scene or two before you add a word, and read the dialogue aloud. In a 2010 Guardian feature of writers' rules, the novelist Helen Dunmore advised: "Listen to what you have written1." A dud rhythm in dialogue, she added, may show you don't yet understand a character well enough to write in their voice. Then check what the next page must respect: who is in the room, what each character knows and what the reader hasn't learned yet. A story bible keeps those facts in one place.
To decide what happens next, look at how your last page ended. Dwight Swain's scene-and-sequel pattern2, as the writing teacher Randy Ingermanson explains it, gives you the next beat. After a setback, the character reacts, weighs a dilemma and decides; after a decision, they pursue the new goal and hit obstacles. If you ask an AI for ideas, treat them as a starting list, not the answer. In a 2024 Science Advances experiment3, eight-sentence stories written with AI-suggested ideas were rated more creative, but they were also more similar to one another.
If AI drafts the next page, give it your last pages, not a summary, and take a few hundred words at a time. In a 2025 Salesforce AI Research study, 18 writers with formal creative-writing training edited 1,057 AI-written paragraphs. Edit yours for what they fixed most4: awkward wording, clumsy sentences, needless explanation and clichés. If you publish through Amazon KDP, its content guidelines5 require you to disclose AI-generated text, even after substantial edits. Text you wrote yourself, even with AI ideas or edits, counts as AI-assisted, which KDP doesn't ask you to disclose.
How it works
How do I continue my story with AI?
To continue your story with AI, paste the last few paragraphs you wrote, or attach the chapter or whole manuscript. River writes about 500 words in the same voice, tense and point of view, starting mid-scene if you stopped mid-scene. The new words land in a doc right after your own lines, under a divider marked River continues, so you always know which words are yours. Your file stays untouched; River reads it for names and facts and picks up from its last line.
The optional directions help when you know the feeling you want but not the words; with none picked, River takes the most natural next beat. Raise the stakes adds a cost, a threat or a deadline, and Bring in a surprise adds one turn that fits everything you've set up. Finish this scene runs until the scene closes, usually 600 to 1,500 words, and Write the next chapter drafts a full chapter that ends on a hook. For a bigger turn, the plot twist generator offers five that fit.
Voice lives in the habits, so River copies them: your sentence length, dialogue punctuation, UK or US spelling and the quirks a polishing tool would sand off. Names, facts and relationships stay as you wrote them, and River won't solve your mystery or reveal what you're holding back. Under the new words, three short notes say what it kept the same. Tap Keep going for more, or Steer what happens next to choose where the story goes.

First person · past tense · your voice
The casserole dish was still warm when Nana handed it to me, which meant she'd made it this morning, which meant Dad had called her. Of course he had.
I went up the stairs the long way, which in Nana's house means looking at the carpet. Michael's door still had the dent from 2009, which meant nobody had fixed it, which meant nobody had wanted to.
"Is the radiator on up there?" she called. It wasn't. I said it was.
Kept: first person, past tense, the "which meant" chains, and what happened to Michael, still unsaid.
What you'll get
The next page of your story, in your own voice
- The next page, scene or chapter, from where you stopped
- Your voice, tense and point of view, kept the same
- Your words and River's clearly marked in one doc
Before and after
Your last lines in. The next page out, in your voice.
The casserole dish was still warm when Nana handed it to me, which meant she'd made it this morning, which meant she'd known since this morning that I was coming, which meant Dad had called her. Of course he had. "You look thin," she said, the way other people say hello. I said I'd been eating. She said eating what. I said food, Nana, and she made the noise, the little click at the back of her throat that has ended more arguments in this family than any lawyer. "Go and put your bag in Michael's room," she said. Michael's room. Like he'd be back for it.
I went up the stairs the long way, which in Nana's house means looking at the carpet. Michael's door still had the dent from 2009, which meant nobody had fixed it, which meant nobody had wanted to. The bed was made with the green blanket. Of course it was. I put my bag on the floor instead, like a guest, and stood there long enough to hear her downstairs not moving. She does that. She stops whatever she's doing so she can listen to you. "Is the radiator on up there?" she called. It wasn't. I said it was.
Same chains, same flat jokes, same thing left unsaid.
What lands in your doc
Your story, continued
- Your own lines, a clear divider, then new words that pick up mid-scene if you stopped mid-scene
- About 500 new words by default, or the rest of the scene, or a full next chapter
- Your tense, point of view, spelling and dialogue style matched, including the odd habits
- Three plain notes on what River kept the same, so you can check the voice yourself
- An ending on dialogue, action or new information, never a tidy reflection, so the next move is yours
- Dark scenes kept dark, and romance at the heat you ask for or your pages already set
Questions authors ask
Common questions
What is an AI story continuer?
An AI story continuer reads the pages you've already written and writes what comes next, in the same voice, tense and point of view. A story generator starts from an idea, and an AI chapter writer from your outline beats; a continuer starts from your last line. Use one when you're stuck on the next page, or want a draft of it to react to.
How do I continue my story with River?
Paste the last few paragraphs you wrote into the box at the top of this page. If earlier chapters hold names, facts or secrets that matter, attach the chapter or the whole manuscript instead. Pick a direction if you like, and River writes the continuation into your free River workspace, under your own lines. Tap Keep going for the next page.
Will the AI story continuer sound like me?
It's built to: River matches your tense, point of view, sentence length and dialogue style from the pages you give it, odd habits included. It doesn't smooth them into polished prose. A short list under the new words names what it kept the same, so you can judge the match yourself. If a line sounds wrong, fix it in the doc, and Keep going follows your version.
Can it write the next chapter of my story?
Yes. Choose Write the next chapter, and River drafts a full chapter under a heading in your style, such as Chapter 8 after your Chapter 7. It runs 2,000 to 3,000 words, or close to the length of your own chapters. It moves the story on with a clear turn and ends on a hook, leaving the book's central conflict open.
Will it keep my story's darkness and heat?
Yes, River keeps the tone you set, so a grim scene stays grim and a horror story stays frightening. Romance stays at the heat you ask for, or the level your own pages set. It never writes sexual content involving anyone under 18 or any real person, and bedtime stories stay gentle.
Can I use it to continue fan fiction?
Yes, if the words you paste are your own, including fan fiction you wrote. To continue another writer's unfinished fic, ask them first, and never post their words as yours. River won't copy passages from published books; it continues in new words. For a brand-new one-shot in a fandom you love, try the fanfiction generator.
Is the AI story continuer free?
Yes, it is free to start, and you don't need a card. Your continuation opens in a River workspace, where you can edit it, share it or ask River to change it. Paid plans add more AI use and access to the most advanced models.
