There is no independently validated “best” detector for every research image. Imagetwin and Proofig AI document broader automated screening features, while FigCheck and Forensically are listed by the University of Utah as free options. The right choice depends on whether you need to find duplicates within one manuscript, search across publications, examine possible manipulation, or screen for AI-generated imagery. Treat every software alert as a lead for expert review—not proof of misconduct.
What scientific-image detection tools can—and cannot—do
Image-integrity screening includes several distinct tasks: spotting repeated figures or panels within a manuscript, finding possible reuse across publications, identifying changes within an image, and assessing whether an image may be AI-generated. A tool that supports one task does not necessarily support the others.
Detection methods may look for similarities despite cropping, rotation, reflection, scaling, color or contrast changes, partial overlap, or copied regions. A 2018 methods paper proposed a manipulation-invariant learned similarity approach and described transformations including rotation, translation, scale, perspective, histogram changes, and partial erasure. It is methodological context, not a performance score for current commercial products: Cicconet et al., “Image Forensics”.
A match or anomaly is not a verdict. Repeated or similar content may have a legitimate explanation, and software cannot establish intent by itself. The University of Utah’s procedure recommends reviewing figures and panels alongside metadata and whether the methods fit the published images. Experienced human interpretation is also emphasized in a Proofig-hosted analyst endorsement.

How the named options compare
| Option | Documented scope | Best comparison points | Limits to weigh |
|---|---|---|---|
| Imagetwin | The vendor lists duplication, plagiarism, manipulation, and AI-generated-image detection; scientific figure categories and common document/image formats; confidence indicators; and a forensic toolbox. | Consider it if you want several kinds of checks and cross-publication searching. Assess supported figure types, privacy and retention, integrations, and report exports. | The vendor says standardized benchmarks are lacking. Its stated detection range comes from internal evaluation and is not independent head-to-head evidence. AI-image detection is labeled beta. Its database size is a vendor claim. |
| Proofig AI | The vendor describes within-manuscript duplicate/reuse checks, single-image manipulation checks, AI-generated-image identification, and comparison against its stated PubMed Open Source Database. Its product page also discusses graphs, charts, diagrams, and plots. | Check the distinction between within-paper checks and cross-publication search, visual-type support, and fit with your institution’s workflow. | Feature and database descriptions are vendor claims, not independent comparative testing. A quoted analyst says experienced review of individual findings remains essential. |
| FigCheck and Forensically | The University of Utah procedure lists these as free options. | They may suit users looking for accessible manual or lightweight forensic aids. | The Utah document describes them as less user-friendly and does not provide a systematic benchmark sufficient to rank them against specialist platforms. |
| Human review and raw-data checks | Utah describes organizing evidence by figure and panel, examining visual-processing methods and metadata, and checking whether methods align with published images. An AMA report notes that some publishers require raw image files. | Use for contextual interpretation, comparison with source data, and compliance with institutional or journal procedures. | It takes expertise and time; no single visual filter proves manipulation or intent. |
Product features and stated database coverage can change. Check the vendors’ current documentation and institutional terms before selecting a service: Imagetwin and Proofig AI. For a procedure-based overview, see the University of Utah Office of Research Integrity.

- Scope: Separate within-manuscript duplicate detection from cross-publication matching and from analysis of changes inside one image.
- Transformations and figure types: Confirm which changes the system says it can detect and whether it supports your material, such as microscopy images, blots, plots, or diagrams.
- Search coverage and traceability: Ask what corpus is searched, how results identify possible source matches, and whether coverage claims are independently audited.
- Data handling: Review upload, retention, deletion, deployment, and access terms. Imagetwin says uploaded files are deleted after processing and that scan results may optionally be saved for 90 days; verify current terms and institutional rules before uploading unpublished figures.
- Review workflow: Check whether reports preserve flagged regions and whether your team can document the tool version, findings, and human decision.
- Validation: Look for independent, directly comparable testing. The reviewed sources do not establish a validated accuracy ranking across these options.
What the published numbers do—and do not—show
The figures below describe different things: vendor-stated corpus sizes, an internal vendor evaluation, and a vendor screening claim reported second-hand. They are not a comparable benchmark set.
| Published figure | What it refers to | Qualification |
|---|---|---|
| More than 160 million published figures | Imagetwin’s stated database size on its product page, accessed 2026-10-04. | Vendor claim; not an independently audited corpus count. |
| 80% to 90% detection rate | Imagetwin’s product-page estimate, accessed 2026-10-04. | The vendor says it varies by image type and concern and is based on internal evaluations involving flagged integrity issues from PubPeer. Standardized benchmarks are lacking; this is not an independent comparative accuracy result. |
| More than 155 million images | Proofig’s stated PubMed Open Source Database coverage on its product page, accessed 2026-10-04. | Vendor claim; not an independent completeness measure. |
| Approximately 25% of manuscripts screened | A Proofig claim reported in the American Medical Association Council on Science and Public Health’s 2025 report. | Second-hand vendor claim about manuscripts screened; the denominator should not be generalized to all research papers. |
For context, the AMA report discusses screening for image manipulation: CSAPH Report 5-A-25. Neither that reported proportion nor the product-page figures establish comparative tool accuracy.

A practical screening and review workflow
- Preserve the originals. Keep the original image data and source files before screening. Where available, record the tool and version used; Imagetwin says its application version appears on the results page and PDF report, and notes that results may vary as detection logic changes.
- Organize evidence by figure and panel. Use consistent labels and retain relevant metadata so a flag can be traced back to its source.
- Run the automated screen. Choose settings and checks that match the question—such as within-paper duplication, cross-publication matches, or possible manipulation.
- Review each alert in context. Compare the flagged region with raw data, neighboring panels, figure legends, methods, and prior publications where relevant. Do not infer fabrication, intent, or misconduct from a software result alone.
- Record findings separately from conclusions. Note what the tool flagged and what the human reviewer found, including any plausible explanation or unresolved question.
- Check rules before uploading or submitting. Review current privacy terms, institutional policy, journal instructions, and any raw-file requirements before using unpublished or sensitive research material.
AI-generated scientific images need particular caution
AI-image detection is not established as definitive in the cited guidance. The University of Utah procedure, dated 2024-02-06, says detection procedures were being tested and can be difficult when original raw images are unavailable. Imagetwin labels its AI-image feature beta. A detector’s result should therefore be treated as an indication to investigate, not proof that an image is synthetic.
The Utah procedure’s practical emphasis on organizing panels, reviewing metadata, and comparing published images with methods and raw material remains important. Where source data are unavailable, the limits of what can be concluded should be recorded explicitly.
