Erotica Apps With Custom Stories

A custom story is one written to your own specification: a prompt, a cast of characters, a set of preferences. The services below do this on demand, and almost all of them use AI. That makes this feature the one where content rules matter most, because the limits come from the model and its filters, not from the app wrapped around it. It is one of the erotica app features we track, and it overlaps with our pages on AI-generated stories and character customisation.

What "custom stories" means, and how it differs from AI-generated

We define custom stories as stories generated to the reader's own prompt, characters or preferences. The caveat that goes with the feature is plain: it is nearly always an AI feature, so the limits on explicit content follow the model, not the app. Ten of the eleven say they use AI. Smuthie's listings never say it, though it generates stories from your choices without saying how.

The difference from AI-generated stories is about who starts it. In an AI-generated library the service decides what to write and you read it. In a custom story you decide, and the service writes. Satinaire sits across the line: its library is AI-written, and its site says If a trope you crave doesn't exist yet, the app can spin one for you.

How we grouped the 11

We grouped on how central the custom story is to each service, using each one's own description. A service not listed has published no answer on custom stories, which is not the same as no.

Custom is the product (8)

For these the prompt is the way in. They differ in what you supply: a form, a scenario, or your own writing.

Service	What you supply	What the free tier gives
Erota	A homepage form: sex acts, themes, perspective, written style, length, language and AI model, with up to four characters	15 daily credits that expire at the end of the day; Apprentice model only
NovelX	A story idea, then character development and chapters; a separate Story Chat	10 generation tokens; what a token buys is not defined
StoryLoom	A genre and a detail, or your own path at each chapter	Two short stories (bobbins) a month, six in total per account
DreamPress AI	Guided wizards for stories and chats, personas, and writing or rewriting on the page	15 daily credits once email is verified, plus 50 bonus credits for verifying
DreamGen	A scenario of its own or one you create, with AI characters	200 monthly credits and 25 daily credits
AI Dungeon	A custom scenario, or a community adventure	A free tier with 4k tokens of context on most models and no monthly credits
NovelAI	You write in a document editor and the model continues; a Text Adventure mode	No free plan; a one-time trial of 50 text generations
Pirr	Genre, vibe, location, plot, character names and pronouns, and your own tags	20 Standard AI actions a day, one character per story, three saved

Custom is an extra on a library (3)

Service	What you supply	What the free tier gives
Satinaire	Characters, names and setting; a trope the library lacks	Free Android app with ads; how much of the custom feature is free is not stated
Smuthie	Tone, setting and characters in "create your own adventure"	None described; both stores show a last update in July 2025
Outfox Stories	AI chats and AI text adventures beside reader-written stories	Free AI use is capped; the Premium page implies about 10 text generations a day

Which of them allow explicit content

This is the part of the feature that decides whether a service is any use to you, and the records sort the eleven into four buckets:

• Explicit is the product: Erota (Custom Explicit Erotic stories written by AI) and NovelX, whose home page title is "AI Erotic NSFW Story Generator".
• Allowed for adults, behind a gate: AI Dungeon through an account-wide Mature setting, Pirr through an opt-in NSFW mode in Advanced Settings that is off by default, DreamPress AI behind an 18+ entry gate with a "Sexual and Erotic Content" section in its policy, Satinaire for content at "spice level 4" or higher, and Outfox Stories for Mature (18+) content under its guidelines.
• Not confirmed: NovelAI and DreamGen, whose terms neither ban nor permit adult content in so many words, and Smuthie, whose adult intent is clear but whose explicitness is not stated.
• Excluded: StoryLoom, whose acceptable use policy says pornographic content is not permitted although its App Store rating is 18+.

"Allowed" is not the same as unrestricted. Every service that allows explicit content also bans sexual content involving people under 18, and AI Dungeon runs a filter for it even on the Mature setting. Our guide to whether AI story apps allow NSFW covers the rules service by service.

Free or paid access, and what a story costs

Nine of the 11 are in the record's free column: Pirr, Satinaire, StoryLoom, AI Dungeon, DreamGen, DreamPress AI, Erota, NovelX and Outfox Stories. Smuthie and NovelAI are not. The free tiers are samplers. They cap you by the day, the month or the account, and some limit the model: Erota's free credits cover only its Apprentice model. See free AI erotica stories for the free options in more depth.

Two services publish enough to work out what a story costs.

• StoryLoom. A full-length story of seven chapters is one spool, $5.99 bought singly. A story you only read costs half a spool, about $3. The Standard plan, $9.99 a month, gives two spools: four read-only stories, about $2.50 each. Plus gives eight for $17.99, about $2.25 each, and Premium twelve for $24.99, about $2.08. Narration changes the sum: a narrated story costs a whole spool, so the same plans give half as many. The choices inside a story are not priced.
• Erota. Its FAQ prices a story at 1 credit on the Apprentice model, 2 paid credits on Artisan and 4 on Master, and listening at 8 credits at Standard quality. Premium is $9.90 a month for 200 monthly credits, so a credit is about 5 cents: roughly 10 cents for an Artisan story and 20 cents for a Master story, before listening. The homepage model picker labels the models "Artisan (3x)" and "Master (4x)", which does not match the FAQ. We record both and do not reconcile them.

For the rest, the cost of one story is not published. DreamPress AI prints credit top-ups, from 400 for $4.99 (1.25 cents each) to 12,000 for $99.99 (0.83 cents each), but not the credit cost of a chapter. NovelX does not define a token, Pirr does not print the credits in its packs, and DreamGen publishes pack prices but not what a generation costs. NovelAI sells unlimited text generation on every paid tier from $10 a month, so there is no per-story sum to do. Our guide to how story app credits work explains why the unit price matters.

What you type, and where it goes

A custom story means typing your own fantasies into a service. The records say little about this, and what they say is worth knowing:

• Pirr's FAQ says stories you create remain private until you decide to publish them yourself.
• DreamGen's terms-and-privacy FAQ says private stories are not used to train models unless you opt in, which is off by default, and that automated moderation scans private content.
• AI Dungeon says private and unlisted adventures are not subject to its community guidelines, though a separate rule against sexual content involving people under 18 applies to them.
• Satinaire's account-deletion page lists custom story drafts and custom characters among the data it deletes.

For the others, the records do not say. See how reading apps use your data for the wider picture.

Limits to know about

• Quality is untested. We have not used any of these services, and a store listing says nothing about how coherent a long story stays. AI Dungeon's published context window runs from 4k tokens free to larger sizes on paid tiers.
• Credits run out. Erota's free credits expire at the end of each day, DreamPress AI's monthly Pro credits do not roll over, and its bought packs never expire. The rules differ by service.
• A stale app. Smuthie has not been updated since July 2025.

Which service suits which reader

These match a need to what the records show. They are not rankings.

• An explicit story from a form, paid by the story: Erota, which publishes its credit costs.
• A playable scenario to steer: AI Dungeon or DreamGen, both with free tiers.
• Writing with the model rather than reading its output: NovelAI, which has no free plan but unlimited text generation once you subscribe.
• Romance with characters you name: Pirr or DreamPress AI.
• A known price per story, and no explicit content: StoryLoom.
• A library first, custom second: Satinaire on Android, or Outfox Stories on the web.
