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.

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.
