Transform Any Visual Material Into Validated Assessments

Leverage the power of AI to create high-utility knowledge checks based only on the content you need to master.

Visual Source Conversion Mastery

Upload images, scanned textbook pages, or entire presentation decks (PPTX, PDF). Our engine uses advanced OCR and context mapping to extract core concepts, ensuring the quiz matches your exact source material.

Deep Explanation-Based Learning

Every multiple-choice question comes paired with detailed rationale for the correct answer and insightful explanations for distractors, promoting deeper understanding rather than simple memorization.

Flexible Mastery & Export Options

Practice instantly in our interactive simulation mode or export finalized assessments in formats compatible with major LMS platforms, including PDF, DOCX, QTI 2.1, and Moodle XML.

From Source Document to Formative Assessment in Three Steps

This is the fastest path to creating tailored, high-stakes practice tests based on specific, proprietary content.

  1. 1

    1. Upload Your Source Material

    Provide the AI with your assets. This can be a typed prompt, a collection of PDFs, DOCX files, or specific images containing lesson diagrams or text blocks.

  2. 2

    2. AI Generates Custom Questions

    Our specialized algorithm analyzes the input, identifies key learning objectives, and constructs robust multiple-choice questions with verifiable answers and comprehensive feedback paths.

  3. 3

    3. Practice or Deploy Your Quiz

    Engage with the quiz interactively to solidify knowledge using active recall, or use our export feature to integrate the finalized set into your offline study schedule or institutional platform.

Why AI-Generated Quizzes Beat Generic Practice Tests

When preparing for a specific module or exam, relying on generic 'lesson to quiz' tools built on broad data sets often results in irrelevant questions. Our AI excels because it bases its formative assessment generation directly on the visual and textual evidence you supply, whether that's a complex diagram from an image file or dense text from a PDF chapter.

  • Ensures 100% curriculum alignment.
  • Provides instant, context-aware feedback.
  • Supports advanced assessment standards via QTI export.

Harnessing this level of specificity is crucial for deep knowledge checks, allowing you to focus your study efforts precisely where your unique source material demands the most attention.

Frequently Asked Questions About Content Conversion

Get answers regarding file compatibility, AI logic, and usage plans.

How does the AI generate questions from an uploaded image?

The AI uses advanced Optical Character Recognition (OCR) combined with contextual analysis models. It reads text within the image, identifies hierarchical concepts, and structures questions based on perceived importance, mimicking how an instructor derives test items from lecture slides.

What specific file types can I upload to generate my custom quiz?

We support comprehensive input methods: PDFs, DOCX files, PowerPoint files (.pptx), and common image formats like JPG, PNG, and TIFF. You can also simply type a prompt for general topics.

Can I export the resulting quizzes for offline use or integration?

Yes, absolute flexibility is key. You can export your generated quiz into standard formats including PDF for printing, Word (DOCX) for easy editing, QTI 2.1 for import into various learning management systems, and Moodle XML.

Is the AI quiz generation service free to use?

The service is free to try, allowing you to test the quality of our generation engine. For high-volume users, academic institutions, or those needing access to our most advanced AI models, we offer paid subscription plans that increase generation credits.
