AI Novelist (AIのべりすと) has long been the go-to AI for continuing Japanese fiction. People still look for a replacement, mostly for three reasons: free members hit an output cap and then have to wait, each output is short, and the shared servers get crowded at night and on holidays. But "an alternative" means different things to different people. Do you want something to continue your writing, something to build a story with from a setting, or would you rather play a story than write one? This guide sorts eight options by what you actually want. Loreon is our product; we judge it by the same standard and say plainly what it is not for.
The short version
- Continue my own writing → AI BunCho, NovelAI.
- Build from a setting or a plot → AI BunCho, Claude, ChatGPT.
- Polish the text in conversation → Claude, ChatGPT, Gemini.
- Play a story instead of writing one → Loreon (in Japanese, no sign-up), AI Dungeon (English).
- Just lose the waiting → an AI Novelist paid plan. Not switching is a fine answer too.
Where AI Novelist's free plan stops
According to the official help pages, you can try short texts without an account; writing longer ones needs a free account (an email address is enough). The main limits for free members:
- Outputs: a cap per hour that moves with server load. Hit it and you can't generate for a while.
- Length: about 250 to 390 characters per output on the free models; paid plans go much further.
- Servers and ads: free members share a server that gets busy at night and on holidays, and see ads.
There are three paid plans: Voyager (¥1,199 a month), Bungo (¥1,980) and Platinum (¥3,465), tax included, per the fan wiki (the official pricing page needs a login). Paid plans get priority output on a dedicated server, so the waits mostly go. If waiting is your only complaint, Voyager is the least effort fix.

AI BunCho — the closest substitute, built for Japanese fiction
AI BunCho is a writing service built for Japanese novels and stories. Give it a setting and it generates a title, synopsis, plot and text, and it has playful formats such as AI relay novels. The free course needs no card and runs on a monthly allowance of AI credits. Paid courses start at ¥550 a month, tax included, and the higher ones add manga generation.
- For: people who, like AI Novelist users, want to write fiction in Japanese.
- Weak spot: saving your work needs a login, and the free tier is credit-based, so writing a lot means paying.
NovelAI — a continue-writing editor, plus images
NovelAI is a subscription service whose continue-writing workflow feels close to AI Novelist. It has a Lorebook for settings the AI should remember, and a text adventure mode. Its newer text model is said to handle Japanese well, but the service and its interface are English-first. Free use is 50 text generations on an email-verified account; paid starts with the Tablet plan at $10 a month.
- For: people who want to manage their world in detail with a Lorebook, or make their own illustrations.
- Weak spot: the trial ends fast, and some find its Japanese less natural than AI Novelist's. More in NovelAI vs AI Dungeon.
Write in conversation
Claude, ChatGPT, Gemini — writing with a general AI
A general AI chat writes when you ask, as in "continue this scene from the hero's point of view, 800 characters". There's no continue button, but you can talk a setting through, revise and rephrase all in one conversation. All three have free plans with usage limits, and they take instructions in plain Japanese.
- Claude: known for reading long context and handling emotion and rewrite notes well. Paid from $20 a month.
- ChatGPT: an all-rounder, from brainstorming to chapter outlines. Paid from Go at $8 a month.
- Gemini: ready to use with a Google account. Paid from Google AI Plus at ¥1,200 a month.
- Weak spot: none of them is a fiction editor, so long works mean pasting earlier material back in again and again.
Play a story instead of writing one
Loreon — AI stories in Japanese, with goals and endings
Loreon is ours, so read this entry with that in mind. Loreon is not a writing tool; it's a story game where the AI is the narrator. Inside an authored story, you type an action in your own words or pick a choice, and the AI tells what happens next. The game tracks your map, items and goals automatically, so nothing you did drops out of the story. You can also write a few lines of setting and get a playable story of your own. Stories and interface are available in Japanese.
You can play as a guest without signing up, or sign in with Google or Telegram. A guest's progress is saved on our servers too, but the guest is recognised only on that device. A new account gets 250 actions and 3 story keys, a turn costs 1 or 2 actions, and a daily reward tops actions back up. We worked out how far the free part goes in free AI story games.
- For: people who were really using AI Novelist to play a story starring themselves.
- Weak spot: it won't help you write your own manuscript. If you want to write a novel, the tools above fit better.
AI Dungeon — the original open AI adventure
AI Dungeon lets you type anything into a blank scenario. Its free plan has unlimited turns, but memory is short and Japanese isn't officially supported. If you're happy playing in English, it's an option. We broke down the free plan in what AI Dungeon's free tier really includes.
How to pick
Start by remembering what you used AI Novelist for. If you were writing your own novel, AI BunCho (strong Japanese) or NovelAI (strong world management) is the closest substitute. If it was a sounding board, Claude or ChatGPT may suit you better. If you were adventuring with the AI, a story game is easier to enjoy than a writing tool; try Loreon. And if waiting is the only problem, switching to an AI Novelist paid plan is the surest fix.
