Help for AICheck's on-device image evidence, provenance markers, and text-pattern reviews.

How accurate is AICheck?

There is no single accuracy percentage we can honestly promise. The text tool is a hand-built, English-focused pattern heuristic and has not been validated as an authorship detector. Its 0–100 pattern signal is not a probability.

The bundled image model was trained on the older CIFAKE dataset. Its source model card warns that performance can drop on newer generators, heavy compression, small images, and unfamiliar content. AICheck therefore uses only a conservative high-signal warning band and never labels a low score “authentic.”

These limits are not unique to AICheck. OpenAI withdrew its own text classifier for low accuracy and warned against primary-decision use. Research has also documented detector evasion and fundamental limits and bias against non-native English writing. That is why AICheck asks you to check drafts, source history, and context instead of accusing someone from a score.

Do you store my uploads?

Text and image checks run on your device by default. See Privacy for details.

What does writing assist do?

The optional writing workspace suggests clearer, shorter, or plainer wording with deterministic rules on your device. You can edit the suggestion before using it, and your draft is not uploaded. It does not identify authorship, establish originality, disguise AI use, or guarantee a result from AICheck or another detector.

Can I start AICheck from Siri, a shortcut, or another app?

Yes, with deliberate foreground actions. On iOS 16 or later, say “Open AICheck scanner,” “Check a photo with AICheck,” or “Check text with AICheck.” In Shortcuts you can connect Take Screenshot, Select Photos, selected text, the Action Button, Back Tap, or a Share Sheet Shortcut to the matching AICheck action. A content action opens AICheck and checks that one item locally because you invoked it; it never watches the other app. A single-image HEIC/HEIF photo is converted locally to a bounded JPEG for the visual model, and the result warns that original Content Credentials and metadata were not evaluated. Android includes an Open Scanner launcher shortcut and can receive plain text or one supported image that you explicitly share to AICheck. A normal Android share is staged for review before checking. This release does not run an accessibility service, overlay other apps, or monitor the screen in the background.

What are Content Credentials?

Content Credentials can carry signed provenance claims about how media was created or changed. For supported embedded image and video credentials, AICheck locally checks the manifest, signature, connection to the file, validation state, and signer trust with the official Content Authenticity Initiative SDK and a bundled checksum-pinned official trust-list snapshot. Remote-manifest fetching is disabled. A “valid” result means the signer was not established as trusted against that snapshot; “trusted” means the trust check also passed. If the validator, local runtime, or trust list cannot complete the check, AICheck reports “unavailable,” not “invalid.” The C2PA's own guidance explains why even a valid manifest does not make content true, and missing credentials do not make content untrustworthy.

What does a video check cover?

AICheck first checks supported embedded Content Credentials locally, then requests eight still frames across at most the first ten minutes. Only confirmed seeks that the image model successfully scores contribute to the median and maximum; failed or timed-out seeks are labeled instead of being counted. Audio and motion over time are not analyzed, so this is not a complete deepfake or full-video analysis.

Why did cloud analysis say metadata only?

Cloud analysis is optional and available only to a server-verified AICheck Pro web subscription after an upload opt-in. When a trained cloud detector is not available, AICheck labels the response as metadata context and keeps the on-device model score unchanged. Native app checks stay on-device in this release.

How do I manage a subscription?

For an active web subscription, open the detector and choose Manage Pro to enter Stripe's secure billing portal. The Stripe receipt email and support are fallback options. iOS subscriptions are managed in App Store account settings; Android subscriptions are managed in Google Play. AICheck never receives your full card number.
