Itch.io Adds a “No AI” Filter, and the Disclosure Question Gets Harder

Itch.io has added a “No AI” filter that lets visitors hide games containing generative AI content from search results and other browsing areas. Engadget reports that applying the filter cut the number of projects shown from more than 1.77 million to fewer than 425,000.

The filter sits on top of a disclosure system the platform already runs. Itch.io asks creators to disclose their use of generative AI when appropriate, and it earlier added a “Generative AI disclosure” field to project edit pages, asking whether a project contains generative AI output. The filter can only act on what creators declare, so its coverage depends on how accurate those self-reported tags are.

Volume is the other half of the picture. Itch.io prohibits uploading excessive amounts of automatically generated or AI-generated content and treats such uploads as spam, according to the same report. The platform's rules therefore draw two lines: disclosure for ordinary use, and a spam classification for mass output.

The pressure behind those rules has been growing. On Oct. 31, Itch.io said via Bluesky that the number of game pages created per day had doubled since August 2026, a figure Polygon reported on Nov. 1. A doubling of daily submissions strains discovery. A browse page, the grid of listings a visitor scrolls through, works reasonably well for a catalogue of a few hundred thousand entries. At 1.77 million, it becomes much harder to scan.

Other storefronts are handling the question differently. Steam has disclosure rules for generative AI use, but it does not currently offer a store filter that excludes such games. Itch.io's filter therefore gives its users a control that the larger storefront does not presently provide.

The broader context here is a familiar one for anyone who has watched digital storefronts scale. Discovery systems built for a smaller library tend to fail first at the margins, and a filter is a blunt instrument. It removes disclosed content from view without judging its quality, and it works only as well as the disclosures behind it. Creators who use generative tools for placeholder art, prototyping or other production tasks may find that a label affects visibility regardless of how the final work was made.

In my view, the more useful question is whether disclosure becomes a norm that developers accept as routine, rather than a stigma they try to avoid. Consistent tagging makes a filter meaningful for players who want human-made projects. Selective tagging turns the filter into a measure of who is willing to disclose. Itch.io's combination of a disclosure field, a spam rule and a browse-level filter gives it levers it can adjust as submission numbers change. What those numbers do over the coming months will show whether the levers are enough.

For players, the immediate effect is simple. Those who do not want generative AI content in their results can remove it with a single setting, and the catalogue they see shrinks from more than 1.77 million listings to fewer than 425,000. For developers, the filter gives the disclosure field a visible consequence, which is a new reason to tag accurately.
