    Upload your source documents (e.g., course syllabi, textbook chapters, vocabulary sheets) or provide a detailed text prompt defining the exact language concepts to cover.

  2. 2

    2. AI Intelligence Extraction

    Our engine analyzes the input for challenging grammatical rules, contextual vocabulary, and comprehension barriers, creating robust questions and plausible distractors.

  3. 3

    3. Review, Practice, and Export

    Instantly review the generated quiz, practice interactively receiving immediate feedback on all options, or export the assessment for use in external learning systems.

Why Explanation-Based Learning is Critical for ESL Proficiency

Effective language acquisition relies heavily on understanding the subtle reasons why a specific syntax or vocabulary choice is incorrect. Generic quizzes often fail here, leaving learners confused about why distractors were wrong. Our AI option explanation generator specifically addresses this gap in formative assessment.

  • Focuses on active recall through immediate, structured feedback.
  • Builds expertise by dissecting linguistic subtleties and common learner errors.
  • Ensures 100% curriculum coverage when generating quizzes directly from your study materials.

By utilizing this tool, you move beyond surface-level knowledge checks toward true mastery of complex English structures, making your preparation highly efficient.

Frequently Asked Questions

Answers regarding our AI-powered testing features.

How does the AI generate detailed explanations for incorrect options?

The AI model analyzes the linguistic rule being tested (e.g., verb tense agreement, preposition usage) and crafts incorrect options (distractors) that violate this rule. The explanation then details the correct structure and explains precisely why the chosen incorrect option fails that structural requirement.

What file types can I upload to generate my ESL quizzes?

We support uploading standard educational formats including PDF documents, DOCX files, and common image files (JPG, PNG) containing written text you want to convert into quiz material.

Can I export the generated quizzes for offline study or LMS integration?

Absolutely. We support robust export options to ensure flexibility. You can export quizzes as standard PDF or Word (DOCX) files, or use specialized formats like QTI 2.1 or Moodle XML for easy import into various learning management systems.

Is the feature that generates explanations for every option available in the free plan?

Yes, core functionality, including generating quizzes with detailed option explanations, is available for free use up to a certain credit limit. Our paid plans offer access to advanced, more nuanced AI models and significantly higher generation capacities.
