itch.io’s No AI filter includes projects whose creators explicitly mark them as not using generative AI. It does not catch pages without a completed AI disclosure, according to itch.io administrator leafo. On November 3, 2026, itch.io announced that it was adding generative-AI disclosure filtering to more parts of the site, including search results (announcement; leafo’s clarification).
What the No AI filter catches
The filter follows a creator’s disclosure. A page must be explicitly tagged No AI to appear under that exclusion; a page with no completed AI disclosure is not filtered out. So the option reflects what creators have declared, rather than automatically detecting AI use across listings.
How itch.io’s guidelines define generative AI
itch.io’s creator guidelines describe generative AI as systems that create new material, such as text, images, or music, from large datasets. They ask creators to disclose generative-AI content and ensure it adds substantial value to the user experience. The guidelines also identify minimally curated, predominantly algorithm- or AI-generated projects, lightly curated random content, and repeated versions of essentially the same content as spam (creator quality guidelines).
The policy distinguishes generative content from self-contained game algorithms. Examples that do not require generative-AI disclosure include NPC pathfinding, enemy behavior, procedural level generation, fuzzy logic, and dynamic difficulty adjustment.
itch.io says disclosure is strictly enforced for game-asset, soundtrack, physical-game, comic, and book pages. Failing to tag those pages may result in delisting.
