You can post AI-assisted stories on AO3 (fanworks only), on Royal Road (with its AI tag) and on Amazon KDP (with a disclosure if the text is AI-generated), but not on Tapas, which has banned AI-generated content since January 2023. If the story is explicit as well, the list gets shorter: AO3 and Literotica take explicit sex scenes, Wattpad takes them only when they "support the story", and KDP doesn't sell pornography at all. Wattpad's rule is the one that changed most recently, on 10 August 2026, and US searches for "wattpad ban" ran about four times higher in the last three months than the three before (720 last month, Google Keyword Planner, October 2026).
Below, each site's AI rule sits next to its explicit-content rule, quoted from the site's own page with the date it was read. Where a page blocked us or says nothing, the table says so instead of guessing.
Where can I post AI-generated stories? The two rules side by side
Checked October 2026: every rule below was read on the platform's own page on 27 October 2026, except Royal Road, whose site refused our requests; its AI tags are quoted from a third-party copy dated 5 October 2026. Rules change; read the linked page on the day you post.
| Platform | AI-written text | Explicit sex scenes | What it hosts |
|---|---|---|---|
| AO3 | Allowed if it's a fanwork; mass posting can break spam rules | Allowed under the Explicit rating | Fanworks only |
| Wattpad | No AI rule in its content guidelines (AI deepfakes of real people are banned) | Mature rating, consenting adults, must "support the story" | Original fiction, fanfic |
| Royal Road | Allowed with an AI-Assisted or AI-Generated tag | Couldn't read its guidelines; check before posting | Web serials |
| Literotica | Its FAQ has no AI rule | It's an erotica site; characters must be over 18 | Erotic stories and poems |
| Tapas | Not allowed (since 23 Jan 2023) | Not checked: AI is ruled out first | Webnovels, webcomics |
| Amazon KDP | Allowed; AI-generated text must be disclosed | Doesn't sell pornography | Books for sale |
| KudoNovel Community Books | Part of an AI writing app | Allowed under the Explicit rating, behind an 18+ notice | Books from a KudoNovel account |
The rest of this page is the fine print for each row, because the summary hides the parts that get stories removed.
Wattpad after the August 2026 guidelines
Wattpad's Content Guidelines carry "Last Revised: August 10, 2026". The sexual-content section now allows, under a Mature rating, "Explicit sexual scenes between consenting adults" and "Sexual content that supports the story, not the main purpose." Content "created primarily for sexual arousal" is in the removed list, and the page adds: "A mature rating is not an exception to our Content Guidelines."
Readers called it a smut ban. Wattpad's line, as Kotaku reported on 18 August 2026, is that its stance on explicit content hasn't changed. Storywatch's explainer (same date) puts it plainly: explicit scenes can stay "when they are part of a broader narrative." The practical reading for a romance writer: a sex scene inside a plot is fine on a Mature story; a story that exists for the scene is the thing the rule removes. Porn-without-plot one-shots belong elsewhere.
On AI, the guidelines are quiet. The one mention is under real person fiction, where stories are removed for "non-consensual AI/deepfakes". We found no sentence about AI-assisted prose, so if you build an audience there, keep an eye on that page.
Can you post AI stories on AO3?
Yes, if the story is a fanwork. The Organization for Transformative Works said in its May 2023 statement: "there is nothing in our Terms of Service that prohibits fanworks that are fully or partly generated with AI tools from being posted to the AO3, if they otherwise qualify as fanworks." The same statement warns that AI works "could violate our anti-spam policies (e.g. if a creator posts a significant number in a short time)," and that the policy is "under discussion internally."
Explicit content is AO3's home ground. Its Terms of Service FAQ defines the Explicit rating as content that "may contain explicit adult themes, such as detailed sex scenes, graphic violence, etc." Two limits matter here: original fiction doesn't qualify, and "all forms of commercial promotion and activities are prohibited," so no links to your paid books. The FAQ also bans "scraping AO3 for the purposes of obtaining material for commercial generative AI", which is about training data, not about your story.
The rules allow AI fanworks; plenty of readers don't. Expect comments, and tag honestly.
Royal Road's AI tags
Royal Road's own pages refused our requests, so this comes from PlotWrite's copy of the rules (checked 5 October 2026), which quotes Royal Road's AI-text policy and its content-guidelines article. AI-Generated means "the story was generated using an AI tool; the author prompted and directed the process, and edited the result." AI-Assisted covers AI used "for editing or proofreading", and a story with a negligible amount of AI-written snippets may use that tag if the author adds "a warning in the author notes on the chapter with the AI-Generated content."
We couldn't read Royal Road's rule on sexual content, so we're not stating one. Read its content guidelines before you post a spicy serial there.
Literotica, Tapas and Amazon KDP
Literotica is the obvious home for erotica, and its footer says "Characters in all stories are over 18." Its FAQ has no rule on AI that we could find on 27 October 2026. No rule isn't the same as a welcome, so read the submission notes when you upload.
Tapas is the clear no. Its announcement of 23 January 2023 says "AI generated content is not allowed to be posted on Tapas. This includes comic and novel episodes, covers and banners."
Amazon KDP draws the line between generated and assisted on its content guidelines page. Text "created by an AI-based tool" is AI-generated "even if you applied substantial edits afterwards", and you must tell Amazon when you publish. If you wrote it and used AI to "edit, refine, error-check, or otherwise improve" it, that's AI-assisted, and "You are not required to disclose AI-assisted content." Separately, the store doesn't sell content that "contains pornography", so explicit erotica on KDP lives in a grey zone this page can't settle for you.
Where this falls short
- Royal Road's rules are quoted from a third-party page because the site blocked us. We say so in the table rather than fill the gap.
- Literotica's and Wattpad's silence on AI could end with one update. Neither page promises anything.
- "Allowed" is the rule, not the reception. AO3 and Royal Road readers can be blunt about AI work, and a tag is no shield against comments.
- None of this is legal advice, and we left out sites whose rules we couldn't read at all (Inkitt and Scribble Hub among them).
A home for the explicit version: KudoNovel Community Books
KudoNovel has its own public library at /library. A writer publishes a book chapter by chapter and can withdraw any of it. Every book carries a rating (General, Teen and up, Mature, Explicit, or Not rated), and Explicit books are allowed: Mature, Explicit and Not rated books show an "I'm 18 or older" notice before reading, and explicit covers stay blurred in listings until then. Readers read free, comment, leave kudos and download an EPUB.
It's a new library, smaller than Wattpad or AO3, and its rule is the plainest on this page: Explicit is a rating, not a reason to take a book down. The book has to be in the app first (written there, or imported from a .docx, .epub or similar file), and publishing is per chapter, so you can withdraw any of it. KudoNovel applies no content filter of its own, so heat level is your call within the law, though the AI model's own behaviour still applies. If you're drafting the explicit cut anyway, start a book in KudoNovel with the free credit and publish the chapters you're happy with.
For the general question of which free site suits a novel, see where to publish your novel online for free. For the writing itself, how to write smut covers heat levels, and which AI tools write explicit scenes covers the drafting.
Before you post
Pick the site by the harder of your two constraints. If the story is explicit and plot-light, Wattpad is out and AO3 (fanfic) or Literotica (original) is in. If AI wrote much of the text, Tapas is out and Royal Road wants a tag. Then open the linked rule page, read it that day, and put a plain line about your process in the author's note.
