Indie game website itch.io expands its AI disclosure filter as ‘AI slop’ continues to overwhelm Steam and other storefronts

Indie game storefront itch.io has taken decisive action against the flood of AI-generated content on its platform, removing approximately “a couple terabytes of AI slop” and implementing new filtering tools for users.

The platform has expanded its generative AI disclosure filters, adding a “No AI” checkbox to search results and other key areas where the filtering was previously lacking. Users can now easily exclude games with AI disclosures from their browsing experience.

The action comes as itch.io faces a significant influx of low-quality AI content. The platform revealed that the number of new game pages created daily has doubled over the past two months, from 3,000 to 6,000, with many submissions being bulk uploads of poorly optimized AI-generated games. Going forward, itch.io plans to de-index spam created through mass uploads.

This mirrors a broader industry problem: 54.6% of titles added to Steam in October 2026 included an AI disclosure label—the first month where AI games outnumbered non-AI titles—compared to just 18.3% in 2025. Unlike itch.io, Valve has not announced similar moderation measures for its platform.

itch.io’s approach emphasizes user choice, allowing those who wish to avoid AI content to do so while maintaining the platform’s openness to creators. The storefront requires mandatory AI disclosures for any game featuring generative AI technology, though creators are not required to specify the extent of AI involvement.
