How to Tag AI-Assisted Fan Art: Rules Across Three Major Platforms

Start with the platform's definition of AI-assisted art

The first question is whether the service considers the final artwork AI-generated, AI-assisted, or conventionally edited. These descriptions are not interchangeable. Generating a complete character portrait, creating a background that forms a substantial part of an illustration, and using automated sharpening on a hand-drawn image represent different levels of involvement. A labeling decision should follow the platform's published definition, not an assumption that every use of an AI-enabled feature has the same status.

A useful distinction is between generative contributions and ordinary image processing. For example, an artist might draw an entire character manually, use an automated tool to reduce noise, and adjust the colors. Another artist might generate the character and background, then repaint several details. The second example has a substantial generative contribution even though the final image contains manual editing. DeviantArt and ArtStation both publish guidance that makes this distinction relevant. Policy information below is current as of October 30, 2026.

• Identify whether AI created visual content or only modified existing content.
• Check whether the platform considers partial generation sufficient for labeling.
• Read separate rules for public posts, portfolio projects, and items offered for sale.

DeviantArt uses a specific AI disclosure label

DeviantArt's Help Center explains that its Created using AI tools label applies when a deviation is made entirely with AI tools or consists primarily of AI-generated components. Its guidance gives an AI-generated portrait that has been touched up as an example requiring the label. It also says that a hand-created illustration based on a description from an AI tool does not automatically require the label. A small, insignificant generated element in an otherwise self-created image is another example that may fall outside the definition.

The submission interface includes a setting for declaring whether artwork was created using AI tools. Metadata indicating AI generation can also trigger automatic labeling. The platform recommends disclosing AI use in the description even when an artist is uncertain whether the formal label applies. For multi-image deviations, all relevant labels should be applied to the submission, even if only one image requires a particular disclosure.

Selling work adds another consideration. DeviantArt says artwork offered for sale must be correctly labeled when it meets the platform's AI definition. Its published guidance warns that incorrectly labeled AI-generated or partially AI-generated sales work may result in refunds or disciplinary action. The separate NoAI label concerns whether other parties may use artwork in AI training datasets; it is not a declaration that the artist did not use AI.

ArtStation separates portfolio disclosure from Marketplace requirements

ArtStation's Terms of Service, Section 46, addresses generative AI in detail. It defines relevant content broadly enough to include characters, environments, backgrounds, objects, textures, and other material creative elements. Work is not automatically treated as AI-created simply because an artist uses tools for noise reduction, upscaling, sharpening, color correction, or similar editing without introducing material generative elements into the final result.

A particularly important distinction concerns distribution. ArtStation requires its CreatedWithAI tag for content distributed through the Marketplace when that content was created using generative AI programs. The platform's September 2, 2026 Help Center explanation confirms that AI artwork is not generally prohibited from portfolios under its content guidelines, provided the creator has the necessary rights to publish it.

The NoAI designation serves a different purpose. ArtStation's terms describe it as a way to identify content that must not be used in generative AI datasets, development, or as inputs to generative AI programs. In September 2026, the platform also announced expanded default NoAI protections for projects. Artists should avoid confusing this protection with the CreatedWithAI disclosure used for generated work.

AO3 provides optional tags for AI-related fan art

Archive of Our Own takes a different approach. The Organization for Transformative Works states that fully or partly AI-generated fanworks may be posted when they otherwise qualify as fanworks. Its July 2024 board explanation identifies optional tags including Created Using Generative AI, AI-Generated Images, and AI-Generated Text. These are additional descriptive tags, not mandatory Archive Warnings.

The distinction matters because Archive Warnings have a specific function in the archive's tagging system. The OTW has explained that it cannot reliably determine whether a fanwork was created with AI, making mandatory AI warnings difficult to enforce. Optional tags allow creators to disclose their process and allow readers to filter or avoid work according to their preferences.

An artist posting a generated illustration as part of a fanwork can use AI-Generated Images to describe that element. If the work also contains AI-generated prose, the text tag may be appropriate. A hand-drawn image made with an AI-generated color palette presents a different situation, and the artist should describe the actual contribution accurately in the notes.

Choose a label that describes the actual contribution

A useful disclosure should explain what the tool contributed, not simply announce that AI was involved. Consider an illustration with a manually drawn character, a generated architectural background, and extensive hand-painted finishing. A caption such as 'Character drawn and painted by the artist; architectural background generated with AI and subsequently repainted' communicates more than a generic AI-assisted label.

Keep platform requirements separate from additional voluntary information. A description cannot replace a required submission label, and an optional tag should not be presented as a compulsory platform rule. The same image may need different disclosures when uploaded to several services because each service defines its own thresholds and submission categories.

• Use the required platform label where one applies.
• Describe substantial generated elements in the caption.
• Disclose AI-assisted text or imagery separately when both appear.
• Keep screenshots or notes describing the creative process when a platform requests supporting information.

The practical differences at a glance

The three services illustrate why a single AI art tag cannot be treated as a universal standard. DeviantArt provides a submission-level disclosure framework, ArtStation distinguishes portfolio rules from Marketplace obligations, and AO3 relies on optional additional tags. Their enforcement mechanisms and purposes are different.

These policies also do not settle every question about ownership, copyright, or whether a particular character design can be commercially reproduced. Platform acceptance is not the same as permission from a rights holder. Before offering fan art for sale, creators should review the relevant rights, event restrictions, and marketplace conditions independently.

• DeviantArt: use Created using AI tools for qualifying deviations.
• ArtStation: use CreatedWithAI for qualifying Marketplace products.
• AO3: consider Created Using Generative AI or AI-Generated Images as additional tags.
