Choose Your Image Integrity Software: How Imagetwin Compares to the Alternatives
Scientific publishing faces a problem of image manipulation and duplication in research, sometimes accidental, which passes through peer review at a rate that damages the credibility of journals, institutions, and researchers. The good news: automated detection tools have matured significantly. The question is which one fits your workflow.
We broke down the image integrity software landscape, and compared Imagetwin vs Proofig, ReviewerZero, Imacheck, and FigCheck, so you can make an informed decision.
The tools in this space
There are currently a handful of automated image integrity tools available to publishers and institutions: Imagetwin, Proofig, ReviewerZero, Imacheck, and FigCheck. They are not interchangeable. They differ in database size, detection scope, pricing structure, speed, and who they are actually built for.
Proofig AI is an image integrity company based in Israel, universities and research centers make up a big part of its customer base, and its pricing model reflects that. ReviewerZero extends beyond image analysis into statistics, citations, and author verification, a broader scope, but less specialized on the image side. Imacheck and FigCheck are narrower tools suited to ad hoc use, without the database depth or publisher integrations that production workflows require.
Imagetwin is built specifically for publishers’ and institutions’ workflows at scale. It is trusted by 8 of the 10 largest academic publishers in the world, including Elsevier, Springer Nature, Wiley, Karger, Sage, Taylor & Francis, and AAAS. Its findings have been cited in ~ 4200 of corrections and retractions on PubPeer, compared to around 67 cases reported for other tools in the space.
Where the real differences are
Speed
Imagetwin returns results in 5 to 30 seconds per manuscript. Most alternatives take 2 to 10 minutes. At submission volume, that gap compounds quickly.
Database
While other tools’ databases are limited to PubMed, Imagetwin checks against 160M+ published figures drawn from open-access and publisher sources, giving it the broadest cross-publisher detection coverage in the market.
Pricing
Imagetwin charges per paper. Proofig charges per sub-image. A paper with 30 sub-images consumes roughly a third of Proofig’s entry-level plan ($99 for 120 sub-images). A heavy manuscript with 100 sub-images costs more than the plan itself. For publishers and institutions screening full submission queues, per-paper pricing, which Imagetwin offers is significantly more predictable and cheaper at scale.
AI-generated image detection
Imagetwin detects AI-generated figures across all life science image types and, uniquely, identifies which generator most likely produced the image: Firefly, DALL-E, Stable Diffusion, ChatGPT, and others. No other tool in this space currently offers generator attribution.
Private repository
Imagetwin includes a free private repository on every plan, including single scans. The equivalent feature in Proofig is available only on enterprise-tier licenses.
File format support
Imagetwin accepts .jpeg, .png, .gif, .jfif, .bmp, .tif, .tiff, .svg, and .webp, plus direct upload of .doc and .docx manuscripts. Proofig is limited to PNG and JPEG only.

Who should use what
Choose Imagetwin if you are a publisher, journal editor, institution, or production partner running integrity checks at submission volume. It is built for that workflow: fast, scalable, deeply integrated with the major submission systems, and priced accordingly.
Choose Proofig if you have a small number of images to check occasionally. Its per-sub-image pricing can work for low-volume, one-off use cases.
ReviewerZero is worth evaluating if you need integrity checks that go beyond images, statistics, citations, and author identity, though it is less specialized on the image side.
FigCheck and Imacheck are low-cost options for ad hoc use, but neither offers the database depth, AI detection, or publisher integrations that production workflows require.
Frequently asked questions
How does Imagetwin detect AI-generated images?
Imagetwin uses machine learning models trained on life science image types to flag AI-generated figures. It goes a step further than binary detection by identifying the most probable generator – Firefly, DALL-E, Stable Diffusion, ChatGPT, and others – with a confidence score per finding.
How does Imagetwin compare to Proofig?
The main differences are pricing model (per paper vs per sub-image), database breadth (160M+ figures vs PubMed only), speed (seconds vs minutes), and AI detection scope. Imagetwin also offers generator attribution and a free private repository on all plans, features Proofig only has available for enterprise customers.
