How automated MCQ generation works with NLP

An automated MCQ generator using NLP starts by reading your material, then picks key facts and turns each one into a question stem with a single correct answer and plausible distractors.

Accepts PDF, DOCX, PPTX, plain text and photos of pages
Produces multiple-choice, true/false and short answer questions
Adds an explanation to every question
Exports to PDF and DOCX on Plus, and QTI 2.1 or Moodle XML on Pro

Example NLP concept questions for MCQ practice

What does tokenization do in an NLP pipeline?It splits raw text into tokens such as words or subwords so later steps can process it. Models cannot analyze an unsplit stream of characters.

Which NLP task assigns a label such as positive or negative to a passage?Sentiment classification. It maps a whole text to a category, which makes it a natural fit for labeled quiz outcomes.

What is a distractor in a multiple-choice question?A plausible wrong option. Good distractors reflect common misconceptions, so they test understanding rather than guessing.

What does TF-IDF measure in a text corpus?How important a term is to one document relative to the whole collection. It weights words that are frequent in one document but rare overall.

Why should a teacher review auto-generated MCQs before use?Generated questions can be ambiguous or have more than one defensible answer. Checking the answer key first prevents students from learning something wrong.

Study now, export later

Practice in the browser on the free plan. Paid plans export PDF and DOCX, and Pro adds QTI 2.1 and Moodle XML for LMS upload.

How it works

Upload your notes

Drop in a PDF, slides, a DOCX file or pasted text.

Review the questions

Check each question and explanation, then edit or remove any that are unclear.

Practice or export

Study in the browser, or export on a paid plan.

Language models identify definitions, dates, causes and named terms, then build a question around each one. Good distractors matter as much as the stem, so the tool favors options that a student who half-remembers the topic might pick.

Generated questions still need a human check. Read each one without its options, confirm exactly one answer is defensible, and rewrite anything ambiguous before students see it.

Frequently asked questions

What makes a multiple-choice question good?

A good question has one clearly correct answer and distractors that reflect common misconceptions rather than obvious wrong choices. The stem should make sense without looking at the options.

How many answer choices should an MCQ have?

Four options is the most common format, with one correct answer and three plausible distractors. Three can work for shorter quizzes, but four usually balances difficulty and clarity.

Do I need to pay to export questions for my LMS?

Yes. PDF and DOCX export are included in Plus, and QTI 2.1 and Moodle XML export are included in Pro. The free plan lets you study in the browser without exports.

No. You can start on the free plan with 3 generations per month and no credit card needed.
