Transform Visual Data into Powerful Assessments

Leverage our expertise in computer vision and NLP to create high-utility assessments derived directly from the sources you study from.

Visual Input Mastery

Upload screenshots, image files, or pasted content directly. The AI excels at reading diagrams, charts, and textbook excerpts to build relevant knowledge checks.

AI-Driven Explanation Engine

Every generated question includes comprehensive, option-by-option explanations, promoting deeper understanding rather than simple right/wrong feedback necessary for effective active recall.

Seamless Export and Practice Modes

Practice interactively for immediate feedback or export your tailored diagnostic quiz to PDF, DOCX, QTI 2.1, or Moodle XML formats for offline study sessions.

The Fastest Path to High-Quality Practice Tests

From image capture to exam readiness in three simple, expert-verified steps designed for maximum learning efficiency.

  1. 1

    Upload Your Visual Source

    Upload PDFs, DOCX files, or paste a direct screenshot/image containing the material you need tested on, or simply type a detailed prompt.

  2. 2

    Let the AI Structure Questions

    Our advanced model analyzes the visual context, extracts key concepts, and automatically generates varied question types complete with robust distractors and detailed justifications.

  3. 3

    Practice Interactively or Export Mastery

    Engage in simulated testing mode for instant self-correction, or leverage our robust export options (PDF, Moodle XML, QTI) to integrate your custom diagnostic quiz anywhere.

Why AI Extraction Beats Manual Quiz Creation

Generating a useful diagnostic quiz used to require hours of manual review. Using our tool to convert a screenshot to a quiz ensures 100% alignment with your source material. This expertise in visual data parsing allows for superior formative assessment creation, pinpointing specific knowledge gaps derived directly from your study resources.

  • Create quizzes from any visual study aid.
  • Ensure assessment validity matches source notes.
  • Focus on active recall through detailed feedback.

This level of input flexibility provides unparalleled authority over your study preparation materials.

Frequently Asked Questions

Expert answers regarding visual data processing and quiz generation.

How does the AI generate questions from an image or screenshot?

The system uses advanced Optical Character Recognition (OCR) and contextual analysis to identify text, labels, and structural elements within the visual input. It then applies pedagogical rules to transform these elements into multiple-choice items, ensuring the questions test core concepts learned from that specific visual aid.

What specific file types can I upload besides screenshots?

You can upload PDFs, DOCX files, and PowerPoint presentations directly. For image-based input, standard formats like JPG and PNG are accepted for generating your custom quizzes.

Can I use these generated quizzes offline?

Absolutely. While interactive practice is available online, our powerful export functionality allows you to save your diagnostic quiz in formats like PDF, Word (DOCX), QTI 2.1, or Moodle XML for offline study and integration into Learning Management Systems.

Is the service completely free, or are there premium features?

The core functionality is completely free to use, allowing you to generate basic quizzes immediately. Our paid plan offers access to a more advanced AI model and significantly increased monthly generation credits for heavy users and educators requiring extensive material processing.
