IMG Performer vs. Disclosio
IMG Performer vs. Disclosio compared: both detect AI images automatically via C2PA and IPTC. IMG Performer also brings image optimization and accessibility alt text.
In short: Disclosio is one of the few competitors that, like IMG Performer, detects AI images automatically via Content Credentials (C2PA) and IPTC metadata. The difference is scope: Disclosio remains a pure labelling tool, while IMG Performer brings image optimization and alt text along.
What Disclosio does well
Disclosio reads Content Credentials (C2PA), IPTC metadata and known generator signatures, and distinguishes AI-generated from AI-modified images. For display there is a floating disclosure button with an accessible popup, and optionally badges directly on the images. An “everything is AI” mode suits sites on which all content is AI-generated. Full WPML/Polylang support for multilingual sites, plus a dashboard with classification statistics. Completely free, no Pro version.
Where it ends
Disclosio is purely a labelling tool. Image optimization (WebP/AVIF) and alt text generation for accessibility are not included – anyone who needs both installs further plugins.
How IMG Performer solves this
IMG Performer also detects AI images automatically from existing C2PA manifests and additionally writes its own XMP/IPTC DigitalSourceType metadata. For images without usable provenance data, manual classification is available as a fallback. The difference to Disclosio is not the detection itself but the overall package: WebP conversion (Free) and AVIF (Pro) as well as AI-assisted alt text for accessibility (Pro, your own API key) run in the same plugin – no second or third installation needed.
