Pixel Analysis mainly presents its CAT (Corrector Automático de Test) product, software for automatically recognizing and grading multiple-choice exams. The workflow is straightforward: the software generates a test template, users print it on ordinary A4 paper, students fill it in, the sheets are digitized with a scanner, and CAT then performs automatic recognition and scoring. The page positions the product as an application of image analysis / machine vision in exam grading.
In terms of features, CAT focuses on grading paper-based multiple-choice tests rather than serving as a general-purpose developer tool. Its key selling point is that it does not require a dedicated optical mark reader; a standard A4 scanner and printer are enough, lowering the hardware procurement barrier. For speed, the page claims that analyzing and grading a single test takes about 2-4 seconds, while 100 tests take about 6 minutes. Detailed analysis can be saved for each participant, and results can be exported as .txt and .csv files, with the latter readable in Microsoft Excel for further statistics. The website also mentions that an English version is available, but it does not specify supported operating systems, installer types, databases, APIs, SDKs, or any plugin ecosystem.
Pricing information is limited. The page only says users can inquire about special offers for individual CAT users; it does not publish pricing, licensing terms, trial policies, or payment methods. The visible support channels are the email address [email protected] and the website contact form. The website copyright shows 2014, and there is no visible changelog, online documentation, FAQ, or service SLA, making it difficult to assess maintenance activity or after-sales responsiveness.
The advantages are a clearly defined use case, an intuitive workflow, low hardware requirements, and CSV compatibility with spreadsheet software. For institutions still using paper-based exams, the time-saving value in grading is fairly direct. The drawbacks are the lack of public information, including compatibility details, data security explanations, API integration, cloud or self-hosted deployment options, and any way to confirm the current version status.
It is better suited to schools, training providers, teachers, or small exam organizers that need to batch-grade paper multiple-choice answer sheets. It is not a good fit for teams that need online exams, question bank management, remote proctoring, or system-level API integration. Access from China cannot be determined from the page alone and should be marked as unknown. Users in China should also consider cross-border communication, payment, language, and after-sales time zone issues, and may want to compare domestic exam-marking systems, online exam platforms, or alternatives such as Remark Office OMR and ZipGrade.
