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.
Why it works
How do I continue my story with AI?
To continue your story with AI, paste the last few paragraphs you wrote, and River writes the next 500 words in the same voice, tense and point of view. They land in a doc right after your own lines, under a clear divider, so you always know which words are yours. Want more than a page? Tap Finish this scene or Write the next chapter, and River keeps going until the scene closes or a full chapter is done.
Voice lives in the habits, so River copies the habits. It matches your sentence length, your dialogue punctuation, your UK or US spelling and the quirks a polishing tool would sand off. Every name, fact and relationship stays exactly as you wrote it. It won't resolve your mystery or spill a secret you're saving for later, and it stops on a live moment instead of a tidy reflection. Under the new words, a short note lists what it kept the same, so you can check rather than trust.
The last lines you paste matter most, because that's where River picks up. If earlier chapters hold facts that matter, drop in the whole chapter or manuscript instead, and River continues from its final line. If what you have for the next scene is a list of beats rather than prose, turn your scene beats into prose instead. To keep names and places straight across a long book, build a story bible from your chapters and keep it in the same space.

Keeping your voice when AI writes the next page
The usual worry with AI continuations is drift. The first paragraph sounds close, then the prose turns smooth, emotionally flat and oddly formal. Characters start agreeing with each other, and a sharp, funny narrator becomes a wise one. River works against that slide by reading your exact lines rather than a summary of them, then writing about 500 words at a time unless you ask for more. Short runs keep the voice close to yours, and you can steer between them or fix a line before it goes on.
The optional directions are there for when you know the feeling you want but not the words. Keep the scene going follows the most natural next beat. Raise the stakes adds a cost, a threat or a deadline. Bring in a surprise adds one turn that still fits everything you've set up. Finish this scene carries on until the scene closes on a live moment. Write the next chapter drafts a full chapter that ends on a hook. For a bigger turn, the plot twist generator finds five that fit.
Work in short loops. Read each run the way a reader would, cut anything you'd never write and fix any line that sounds off. When you tap Keep going, River rereads the page with your edits and follows them. Stuck on what happens next rather than how to say it? Pick Bring in a surprise and keep only the turn you like. If you self-publish, Amazon KDP's content guidelines ask you to disclose text an AI tool generated, even after you edit it.
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; a continuer starts from your last line. This one writes about 500 words by default, or finishes the scene, or drafts the whole next chapter.
Will the AI story continuer sound like me?
That's the whole job. River matches your tense, point of view, sentence length and dialogue style, odd habits included, and lists what it kept the same so you can check. It doesn't smooth your style into something more polished. If a line sounds off, change it in the doc; River treats your edit as the voice to follow.
How much of my story should I paste?
A few paragraphs is enough, because River picks up from your very last line. If earlier pages hold names, facts or secrets that matter, drop in the chapter or manuscript as a Word, PDF or text file. River reads it and works in a new doc; your file stays as it is.
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 level you choose, which River reads from your own pages. It never writes sexual content involving anyone under 18 or any real person, and bedtime stories stay gentle.
Can I continue someone else's story or fan fiction?
Paste your own writing. Continuing your own fan fiction is fine. For someone else's abandoned fic, fan communities generally expect you to ask the author first, and you shouldn't post their words as yours. River won't reproduce long passages from published books. For a brand-new one-shot in a fandom you love, try the fanfiction generator.
Can it write the whole next chapter?
Yes. Tap Write the next chapter and River drafts a full chapter, usually 2,000 to 3,000 words, picking up from what happened last and ending on a hook. It follows your chapter headings and chapter length when it can see them. After any run, tap Keep going and River continues from its last line, or from your edits.
