The NovelAI alternative built for a long, chaptered novel is KudoNovel: you write beat by beat, the story bible and a running summary of the whole book update themselves as you go, and nobody maintains a Lorebook to keep chapter 30 true to chapter 1. There's no subscription, either. You buy a one-off pack when you're writing and nothing bills you in the months you're not.
Here's why that matters. NovelAI's top tier, Opus, costs $25 a month and gives its text models up to 28,672 tokens of context (checked October 2026). That's a generous window for a scene. For a novel, it's roughly the last several chapters. Everything further back reaches the AI only through the Memory box, the Author's Note and the Lorebook entries you write and keep current. At 80,000 words, that upkeep is usually the reason you typed "NovelAI alternative" in the first place.
Checked October 2026: every NovelAI price and limit on this page is from NovelAI's own subscription docs, linked where it's quoted. Check them for current plans before you decide.
Coming from the other direction? AI Dungeon's context limits in words are set out in the same way.
What NovelAI costs right now
NovelAI is a subscription, in US dollars, and if your card won't go through, why a NovelAI payment gets declined covers the causes NovelAI itself names. From its subscription docs, checked October 2026:
| Tier | Price | What you get |
|---|---|---|
| Paper (free trial) | $0 | 50 text generations, 30 image generations and 100 text-to-speech generations, with a verified email |
| Tablet | $10 a month | Unlimited text generation and text-to-speech, plus 1,000 Anlas a month for images |
| Scroll | $15 a month | Everything in Tablet with a larger context size |
| Opus | $25 a month | The largest context (up to 28,672 tokens), Xialong plus the older Krake and Llama 3 Erato, and 10,000 Anlas a month |
NovelAI's homepage says story generation is "powered by GLM 4.6", so check which model you'd actually be writing with.
The word to notice is unlimited. On every paid tier, text generation doesn't run down a meter, and if you reroll a paragraph thirty times that's a real convenience. What the meter-free generation can't do is see past the context window. Unlimited continues of the last few chapters are still continues of the last few chapters. For a long book, the limit that costs you is memory, not generations.
How a NovelAI alternative handles memory
In KudoNovel, there's no Lorebook to keep and no activation keys to set. You write in beats, a paragraph each, inside chapters, and the story bible (characters, places, items and events, each with aliases) and the summary of the whole book keep up as you write; instead of waiting for a keyword to fire, an entry goes to the AI when the engine judges the passage needs it. When a character changes sides in chapter 19, the bible says so by chapter 20 because the bible read chapter 19, not because you remembered to edit an entry. Both sit in the sidebar, readable and editable.
In NovelAI, the AI sees the recent text of your story up to your tier's context limit. Everything else comes from three things you write. The Memory box holds broad facts about the setting and characters. The Author's Note sits close to the end of the context and nudges where the scene goes. And the Lorebook holds entries for characters, places and objects; an entry is inserted when one of its activation keys shows up in the recent text, or always, if you set it that way. Keeping them accurate as the plot moves is your job, and the Lorebook keeps saying she's loyal until you go and fix it.
That system is powerful, and it gives you exact control over what goes into context and when. KudoNovel gives you the same control at the moment it counts: your steer outranks everything else the engine planned, and you can correct any bible entry by hand. The difference is who does the bookkeeping between those moments. In KudoNovel, the app does.
What NovelAI does well
- Flat price, unlimited text. Retry a paragraph thirty times and it costs the same as once.
- Fine control over generation. Generation settings, a keyword-driven Lorebook, the Memory and Author's Note boxes.
- Images and voice in one subscription. Anime-style image generation and text-to-speech come with the same plans.
- Browser-side encryption. NovelAI's FAQ says stories are encrypted in your browser before they're stored.
- A permissive stance. Its homepage promises "No restrictions. No compromises." for its image tool, its storytelling models are tuned for fiction, and its FAQ describes moderation for images only.
If what you want is a co-writing scroll where the AI continues your text and you steer it line by line, NovelAI is a fine way to write. A finished novel that stays consistent across thirty chapters is a different job. And if you only want a short piece without paying, each free AI story generator has limits of its own, checked.
Is a NovelAI alternative cheaper? Pricing side by side
| NovelAI | KudoNovel | |
|---|---|---|
| Model | Subscription, $10, $15 or $25 a month (checked October 2026) | No subscription. One-off packs: $3.50 for 100 credits (about a short novel), $7.50 for 500 (about a full book), $12.50 for 1,000 |
| Trying it | 50 text generations on the NovelAI free trial | 1 free credit on sign-up, after email confirmation, no card |
| Your own AI key | Not offered | Not needed: runs its own built-in model, no key to set up |
| What the price buys | Text, images and voice | The writing only |
The shape is the difference. A subscription bills you in the months you don't write; a pack sits there until you do. A beat (expand and the bible upkeep that comes with it) is roughly one credit, and a simple Expand about a fifth of one, so $7.50 is in the region of a full book.
NovelAI vs KudoNovel at a glance
| NovelAI | KudoNovel | |
|---|---|---|
| Writing style | A co-writing editor that continues your text | Beat by beat, a paragraph each on the chapter's page, with three Expand levels and a one-line steer |
| Long-range memory | Memory, Author's Note and a keyword-triggered Lorebook you maintain | A story bible and a whole-book summary that keep up as you write |
| Price | Monthly subscription, unlimited text | One-off credit packs, AI included |
| Images and voice | Included | KudoNovel is writing only: the price buys prose |
| Content | Moderation described for images only | No filter of KudoNovel's own; romance, horror, dark and explicit themes are your call within the law, and the model's own behaviour still applies |
| Where your book lives | Encrypted in the browser | Saved to your account automatically and continuously, on every device you open; AI requests on the built-in credits go only to zero-data-retention hosts that don't train on prompts |
| Getting it out | .story and .scenario files, or plain text | Plain text, Markdown, HTML, EPUB or PDF, and finished chapters can be published to Community Books |
| Getting it in | Its own formats | .docx, .epub, .odt, Markdown, Scrivener, NovelAI .story and more; a NovelAI lorebook imports as bible entries |
When KudoNovel is the better NovelAI alternative
Once keeping the Lorebook true has become a second job. That's also when unlimited generations stop helping: thirty rerolls of a scene that has forgotten who betrayed whom are thirty rerolls of the same mistake. KudoNovel meters per request instead, and the meter moves only while you write: a $7.50 pack is about a full book, nothing bills in a quiet month, and the price buys prose rather than an image and voice allowance you may never touch. The freedom you came to NovelAI for carries over too. KudoNovel has no filter of its own, and its built-in model is picked partly because it rarely refuses.
Moving a NovelAI story over
NovelAI lets you export a story as a .story file or as plain text. Either one imports into KudoNovel (My Books → Import), and the lorebook you've been maintaining comes in as story-bible entries, so the upkeep you've already done carries over and the bible keeps them current from there. The free detector finds chapters and scene breaks; when a file gives it nothing to go on, an optional AI split does the job at a price shown before you click.
Or try it on a side piece first: start a book in KudoNovel on the one free credit you get after confirming your email, and watch the bible fill in from what you write.
If the real issue is that every AI you use loses the plot past a certain point, read why AI forgets your story. If you write the kind of fiction mainstream chatbots refuse, this explainer on writing with no content filter is worth your time. For NovelAI against Sudowrite, there's a separate comparison.
