Visual AI likelihood
A structured score summarizes how strongly the visible details resemble patterns associated with AI-generated or AI-edited images.

Free AI Image Detector
Look for AI signals. Keep the conclusion honest.
Use our free AI image detector to estimate whether an image was generated or substantially edited with AI. The result is a likelihood assessment—not a claim of certainty.

A useful signal,
with its limits attached.
The detector is designed to help with review and verification—not to turn one probability into a verdict.
Concise visual context
When AI-associated patterns are found, the result highlights the most relevant signals without overwhelming the core score.
Honest interpretation
The result keeps image likelihood separate from certainty and reminds you when source context or additional review still matters.
How to use it
Three steps from image to informed review.
Use the original file when possible. Screenshots and heavily compressed copies can remove useful signals.
- 01
Upload one image
Choose a JPG, PNG, or WebP file up to 10 MB. The browser checks its type and size before sending anything.
- 02
Run the free analysis
The server sends the image to the visual analysis model and returns a structured assessment rather than an unexplained number.
- 03
Read beyond the number
Compare the result with the source, provenance information, visible edits, and the context in which the image appeared.
Reading the score
Confidence bands, not courtroom labels.
Thresholds organize the report. They do not create certainty where the underlying model is uncertain.
Low AI likelihood
Few known AI-generation signals were found. This does not prove the file is authentic or unedited.
Mixed or uncertain
Some signals are present, but compression, editing, illustration style, or an unfamiliar model may complicate the result.
High AI likelihood
Strong patterns associated with generated or substantially AI-edited imagery were detected. Confirm with other evidence.
Important limitations
What can change the result?
AI image detection is an evolving classification problem. A result can shift as models, image transformations, and detector training data change.
- 01
Screenshots and compressionRepeated saving, social-media compression, or large areas of interface chrome can weaken visual signals.
- 02
Partial AI editingInpainting, generative fill, face replacement, and retouching may affect only part of an otherwise real photograph.
- 03
New or uncommon generatorsA detector can be less certain when a generator family was not represented well in its training data.
- 04
Stylized human artworkDigital illustration, heavy filters, CGI, and unusually smooth photography can resemble synthetic patterns.
Privacy by design
Processed for the check. Never added to a gallery.
No public URLNo gallery storage
UltraHumanizer does not write uploaded images to its own storage or create a public URL. The selected file is held by the browser, transferred through our server to the configured AI analysis provider, and used to return the requested assessment.
Do not upload confidential client work, IDs, medical imagery, private photos, or unreleased creative assets until you have reviewed the applicable privacy policy and are comfortable with third-party processing.

Build context around an AI image check
How to check whether an image may be AI generated
Begin with the best available file. A screenshot of a social post may contain interface elements, resized text and compression that were absent from the original image. Upload a JPG, PNG or WebP of up to 10 MB, sign in and run the AI image checker. Read its explanation together with the likelihood band, then return to the source of the image.
Ask who first published the file, what the caption claims and whether an earlier version is available. Visible oddities can guide closer inspection, but retouching, illustration, lighting and compression can also create unusual details. A clean-looking image is not automatically a camera original, and a single unusual hand or reflection is not enough to establish how the whole picture was made.
What the AI image detector does—and what needs another check
A visual assessment is most useful when its scope is clear. UltraHumanizer reviews the uploaded pixels for AI-associated patterns; it does not provide an independent investigation into the publisher, the event or the identity of a person shown.

| Review step | What it adds |
|---|---|
| Run the visual model | An AI-likelihood assessment and concise visual context for the supplied image. |
| Locate an earlier source | Publication context that may explain cropping, editing or a misleading caption. |
| Inspect available provenance records | Additional information about the file’s history; verify it separately from this tool. |
| Compare an original and an edited copy | A way to narrow down where changes may have occurred. |
- Partial AI editing can coexist with a real photograph; a whole-image score does not identify every altered region.
- The tool does not authenticate Content Credentials, search the web for matching images or establish copyright ownership.
- Keep the source file and the context used for your decision rather than relying on a screenshot of the score alone.
Frequently asked questions
AI image detection, answered carefully.
Clear guidance on scores, accuracy, formats, privacy, and the limits of visual detection.
What is an AI image detector?+
An AI image detector reviews visual patterns in an uploaded image and estimates whether generative AI was involved. UltraHumanizer currently uses a visual AI model to produce a structured likelihood assessment with concise context. It is not definitive proof of authorship or origin.
Can an AI image detector be 100% accurate?+
No. New generators, heavy compression, screenshots, cropping, filters, and partial AI edits can all affect a result. Use the score as one signal alongside provenance, source context, metadata, and human review.
Is the UltraHumanizer AI image detector free?+
Yes. Sign in for 3 image checks per UTC day on Free. Basic, Pro and Ultra include unlimited daily uses, subject to request and file limits. No payment is needed for the Free allowance, and Humanizer monthly words are separate.
What image formats are supported?+
The UltraHumanizer AI Image Detector accepts JPG, PNG, and WebP files up to 10 MB.
Does UltraHumanizer save uploaded images?+
UltraHumanizer does not write uploaded images to its own storage. When detection is enabled, the image is transferred to the configured detection provider for processing. Do not upload confidential or sensitive images without reviewing the current privacy terms.
Can it identify which AI generator made an image?+
Not reliably. A visual model can recognize patterns that sometimes appear in generated images, but it should not be used to attribute an image to a specific generator without stronger provenance evidence.
Can a low score prove an image is real?+
No. A low score means the detector found fewer known AI-generation signals. It does not prove camera provenance, rule out manipulation, or establish who created the image.
