Check image source evidence locally, free and unlimited without registration. Choose optional CommFor analysis only when you want an additional AI-generated score and accept uploading the image for 1 credit.
Check evidence before interpreting a score
- Choose the closest available original. Phase 1 reads the file in your browser without uploading it.
- Review Technical, Provenance and AI traces, including the status of layers that could not finish.
- Only click the optional CommFor action if you accept its image upload and 1 credit cost. An inconclusive local check never starts it automatically.
Read the local evidence
Technical checks inspect file structure and ordinary EXIF. Provenance checks inspect embedded Content Credentials and their available validation states. AI traces include IPTC/XMP source fields, domestic AIGC labels and generation parameters from both Automatic1111 and ComfyUI. A readable issuer or application name is a stored claim, not proof of its author.
Supported public SDXL-compatible pixel watermarks are checked locally. SDXL, SD3 and FLUX names can also be mapped from stored labels; a name match is not a verified pixel watermark. GPS and prompts stay hidden until you choose to reveal them. Expand details for conflicting, unsupported, failed or skipped layers.
Two stages, separate meanings
Based on established AI image detection research. Local evidence and a pixel model answer different questions.
| Stage | What it reports | Processing and price |
|---|---|---|
| Phase 1: local inspection | Technical, Provenance and AI traces; AI evidence score summarizes supported evidence | Browser-only, no image upload, unlimited and free |
| Phase 2: optional CommFor | An AI-generated score from image pixels; no deepfake or generator classification | Explicit user upload; 1 credit for a completed result |
AI evidence score is not a probability
The local AI evidence score describes rule-based evidence strength. It is not a calibrated probability that an image is AI-generated. Repeated labels from the same source do not become independent evidence. Missing metadata neither proves human authorship nor makes every other detection layer ineffective.
Not calculated means no score was produced. Unavailable means a layer could not complete; neither means zero. The optional CommFor score is a separate model output, not an authenticity certificate. Compression, editing and unfamiliar images can affect it. No site-specific fine-tuning or representative accuracy benchmark is claimed.
Historical examples and their limits
Our September 15, 2026 integration examples used OpenAI and Hive. Those integrations are now paused, and those scores are not CommFor results. The cases demonstrate why a changed file, missing credential and unavailable check must remain distinguishable; they do not validate the current model.
Try optional analysis
Visitors receive 1 credit once. Registration grants 3 credits once, and the first sign-in each day grants 3 credits. The registration and daily sign-in gifts are separate, including on the registration day. Gift credits expire after 7 days and eligibility is subject to abuse prevention. Local inspection never uses these credits. PayPal purchasing remains unavailable.
Frequently asked questions
Is the free check a universal AI detector?
No. It inspects supported local evidence. Missing signals do not rule out AI generation, and failed layers are shown separately.
Will the free check upload my image or spend credits?
No. Phase 1 is local and unlimited without an account. CommFor requires a separate explicit upload action costing 1 credit.
How accurate is the AI photo detector?
No representative accuracy benchmark is claimed. Use the local evidence and optional model score alongside original sources and publication context.
Does deleting metadata make an image undetectable?
No. Supported pixel watermarks and optional pixel-model analysis are separate from ordinary metadata.
Can I check a screenshot?
Yes, within the supported file limits. Its metadata describes that copy and may omit original provenance; missing signals do not establish human origin.
Does CommFor identify deepfakes or the generator?
No. The optional model reports an AI-generated score. It does not supply deepfake, face-swap or source-model classification.
