Quick answer
- Unlimited text at a flat price: NovelAI is $10, $15 or $25 a month with unlimited text generation and a memory of 8,192, 12,288 or 28,672 tokens. AI Dungeon's paid tiers start at $14.99 for 8k of context.
- Free: DreamGen gives 200 monthly and 25 daily credits free, and AI Dungeon's own free tier has 4k of context on most models. NovelAI has no free plan, only a one-time trial of 50 text generations.
- Stated adult rules: AI Dungeon has a Mature level you confirm as 18+. DreamPress AI and Outfox Stories state that adult content is allowed. NovelAI and DreamGen state neither a permission nor a ban for adult content.
- On a phone: AI Dungeon, DreamPress AI (iPhone) and Pirr (iPhone and Android) have store apps. NovelAI and DreamGen are web only.
- Not like for like: Pirr and NovelX are story apps, not typed adventures, and model quality is something we cannot judge.
Why look for an AI Dungeon alternative
AI Dungeon is an open-ended text adventure from Latitude, Inc. where you type actions and speech and the model continues the scene. Our AI Dungeon review has the record. The reasons to compare are about the model, the context window and the rules:
- Context rises with price, steeply. The pricing page gives the free tier 4k tokens on most models, 2k on Madness, Hearthfire and Harbinger and 3k on DeepSeek V4 Flash. Journey, $14.99 a month, gets 8k, Legend at $29.99 gets 16k, Mythic at $49.99 gets 32k and Ultimate at $99.99 gets 64k. The help page still says Mythic and Ultimate get 32k; two official pages disagree.
- More context can be bought with credits. Paid tiers include monthly credits (760 on Journey), and some models spend them on extra context, for example 4k tokens more per credit on Dynamic Large. Extra credits "can be bought separately" and their price was not recorded.
- Three more tiers sit above that. Web-only "Shadow Tiers" are listed at $246.66, $496.66 and $996.66 a month, monthly only, and not sold in the apps.
- The adult setting has conditions. A Safety Setting runs Safe, Moderate, Mature, and Mature needs you to confirm you are 18+. An in-play filter still blocks sexual content involving people under 18, fictional characters included, even on Mature. Public content must be rated and has its own bans, while Private and Unlisted adventures are not moderated beyond what AI Dungeon calls its Walls Approach. Whether Mature works on the free tier is not stated.
- Billing is hard to read. The iOS list is truncated to ten items, mixes legacy names such as Champion and Adventurer, and shows no period. Refunds are at the company's sole discretion, with no refund for partially used periods, and Apple subscribers must go through Apple.
Every tier is laid out on what AI Dungeon costs, and the service's live pricing page carries the current figures.
The best AI Dungeon alternatives, by what you want to change
We picked six and ordered them from the closest typed-story experience to the furthest. Each pick says what it changes on model, context, price or rules. The NovelAI page asks the mirror question, and the alternatives hub lists both.

NovelAI
Best for unlimited text at a flat price, and for privacy
$10.00/mo
- Type
- Subscription AI storyteller and anime image generator (web app)
- Free tier
- No

NovelAI is a subscription AI storyteller from Anlatan Inc. with a document editor where the model continues your text, a Text Adventure mode with Do and Say commands, and unlimited text generation on every paid tier. Tablet is $10 a month with a memory of about 32,768 characters (8,192 tokens), Scroll $15 with 12,288 tokens and Opus $25 with 28,672 tokens plus Opus-only models. The homepage says story generation is "powered by GLM 4.6", and the tier table names Llama 3 Erato 70b as an Opus model. Its privacy policy summary says "your stories are end-to-end encrypted and we cannot read them, and we do not store the prompts you send for generation", which is the company's statement and not something we tested.
What it drops: there is no free plan, only a one-time Paper trial of 50 text generations, and no native app (it installs as a web app). Its terms require users to be 18 or older, but we found no sentence permitting adult content, none banning it, and no published rule on sexual content involving people under 18, which describes the pages we read and not a policy it lacks. Refunds are only if the company grants them. AI Dungeon against NovelAI compares them.

DreamGen
Best free tier, with role-play and credits
$7.83/mofree tier
- Type
- AI story writer and role-play platform (web)
- Free tier
- Yes
- Library
- Not confirmed
- Explicit content
- Not confirmed: the Terms do not ban adult content but no sentence states that explicit content is permitted
- Creator program

- Web version
- Yes
DreamGen is an AI story writer and role-play platform where you define a scenario and play with AI characters. The free product has 200 monthly credits and 25 daily credits. Starter lists at $7.83 a month with a 5,000-token context, Advanced at $19.35 with 15,000 and Pro at $48.30 with 30,000, with credit packs of 750 for $5.39 up to 9,000 for $51.79. The first-party default model is described as GLM 5.2, free of credits for Pro users, and third-party models cost credits.
The price is not as flat as it looks. The "unlimited" on paid tiers carries an asterisk and monthly token caps, and the free tier's context window is not stated. It is web only, with no store app found. The Terms bar sexual content involving fictional people under 18, but no sentence permits or bans adult content between adults, and the Terms and Privacy FAQ say private stories are not used for training unless you opt in while automated moderation scans private content.

Outfox Stories
Best for an adults-only site with human-written stories beside the AI
$8.00/mofree tier
- Type
- community fiction site with an AI layer (web)
- Free tier
- Yes
- Library
- Not confirmed
- Explicit content
- Yes
- Creator program
- Yes
- Web version
- Yes
Outfox Stories is for people 18 and over only. Its readers write branching stories, and it has AI chats and AI-generated text adventures, with a free tier and Basic at $8 a month, or $6 on an annual subscription, which gives 100 text generations a day, ten times the free tier. Plus is $20 with 500 a day and Patron $100 with virtually unlimited generations. The Premium page says "The AI will write mature content", and the Content Guidelines welcome explicit fiction under written rules. The site meta promises no ads and no account required.
No context size, model name or token count is published in the pages we read, so it cannot be compared on those terms. AI images and videos are always SFW, a one-time age verification applies in some regions, and it is a website. It suits a reader who wants community fiction as well as an AI adventure.

DreamPress AI
Best for chaptered stories with narration and a stated adult rule
$9.99/mofree tier
- Type
- AI story generator for spicy and general fiction (web and iOS)
- Free tier
- Yes
- Library
- Not confirmed
- Explicit content
- Yes
- Creator program
- Not confirmed
- Web version
- Yes
DreamPress AI writes chaptered stories with choices, roleplay chat and AI narration. A free account gets 15 credits a day once its email is verified, 50 bonus credits for verifying, and 20 a day from day 7 of a writing streak. Pro is $9.99 a month or $71.99 a year on the web, with 1,000 credits a month, and the iPhone app charges more: $12.99 for the same tier. It has an 18+ entry gate, an adult content policy that says all characters must be over 18, and an iOS app.
It drops typed freedom for structure, and context sizes and the cost of a chapter in credits are not published. There is no Android app that we found. Terms and policies were last updated August 13, 2026.

Pirr
Best for a romance app on iPhone and Android
$12.99/mofree tier
- Type
- Interactive romance fiction app (iOS, Android, web beta)
- Free tier
- Yes
- Audio stories
- No
- Interactive stories
- Yes
- AI stories
- Yes
- iPhone app
- Yes
- Android app
- Yes
Pirr is an interactive romance fiction app: you choose the genre, characters and setting and the story adapts line by line, in text only. The free tier gives 20 daily Standard AI actions, and Premium is $12.99 a month or $99.99 a year on the App Store. It has iPhone and Android apps and a web beta, and Mature themes are off by default for users who confirm they are 18 or older. Its Code of Conduct says all characters in sexual content must be 18 or older.
It is not a typed adventure and publishes no model or context size. It is the pick if you want the AI-adapted story in an app.

NovelX
Best for listening to AI stories, with a policy gap to check
$18.99/mofree tier
- Type
- AI erotic and romance story writer (web and iOS)
- Free tier
- Start Free: 10 generation tokens
- Library
- 89,000+ stories written
- Explicit content
- Yes
- Creator program
- Not confirmed
- Web version
- Yes
NovelX is an AI erotic and romance story writer on the web and iPhone from Sub Zero Labs OÜ of Tallinn. You describe an idea, build characters, generate chaptered stories and listen to supported chapters as audio. A free plan gives 10 generation tokens, Premium is $18.99 a month on the web and the App Store, and a homepage counter claims 89,000+ stories written.
The gap is on its own pages. Its Acceptable Use Policy and homepage FAQ ban incest and non-consensual sexual content, while on October 27, 2026 its public library listed tags for both, which we record as a fact about the service and not a finding about any story. What a free "token" buys is not defined, and context and model are not published.
Context and price, as published
Context windows decide how much of your story the model can see at once. This table sets out what each service publishes. The last column is our arithmetic, price divided by thousands of tokens, treating AI Dungeon's "k" as 1,000. It says nothing about how good the writing is, because the models differ.
| Service and plan | Price a month | Context as published | Price per 1,000 tokens |
|---|---|---|---|
| AI Dungeon, free | $0 | 4k on most models | Not applicable |
| AI Dungeon, Journey | $14.99 | 8k | $1.87 |
| AI Dungeon, Legend | $29.99 | 16k | $1.87 |
| AI Dungeon, Mythic | $49.99 | 32k | $1.56 |
| AI Dungeon, Ultimate | $99.99 | 64k (the help page says 32k) | $1.56, or $3.12 on the help-page figure |
| NovelAI, Tablet | $10 | 8,192 tokens | $1.22 |
| NovelAI, Scroll | $15 | 12,288 tokens | $1.22 |
| NovelAI, Opus | $25 | 28,672 tokens | $0.87 |
| DreamGen, free | $0 | Not stated | Not applicable |
| DreamGen, Starter | $7.83 list | 5,000 tokens | $1.57 |
| DreamGen, Advanced | $19.35 list | 15,000 tokens | $1.29 |
| DreamGen, Pro | $48.30 list | 30,000 tokens | $1.61 |
NovelAI's three plans are the cheapest per 1,000 tokens in the table, and they include unlimited text. AI Dungeon offers what NovelAI does not: a free tier, store apps and a published safety system. DreamGen's prices are struck-through list prices, with a first-month discount that applies once, and its paid tiers carry monthly token caps behind the word unlimited. The other four services, Outfox Stories, DreamPress AI, Pirr and NovelX, publish no context size in the pages we read.
AI Dungeon and its alternatives side by side
AI Dungeon is first. The Explicit content column quotes each service's own stance, and cells that read Not confirmed mean the pages are silent.
