Is Questgen free?
Partly. Questgen's Basic plan is free and includes 20 runs, which is enough to test it on a few documents. After that, the Pro plan costs $15 a month or $100 a year and gives unlimited runs under a fair use policy. Prices were taken from Questgen's pricing page on August 3, 2026.
QuerySpark works differently: every new account gets a 3-day Pro trial with no card, then drops to a free plan with 1 study session, 20 generated questions, 20 flashcards and 10 PDF pages a month. Student costs $9 a month, or $7 a month billed yearly ($84 a year). If you only want to see the question quality first, the free question generator takes up to 6,000 characters of pasted text, 3 times a day, with no account.
Which question types does each tool make?
Questgen makes more formats. Its site lists multiple choice, multiple choice with more than one correct answer, true/false, fill-in-the-blank, matching, FAQ-style questions, short answer and higher-order questions, and it can target any of the six Bloom's taxonomy levels.
QuerySpark makes four: multiple choice, true/false, short answer and essay, each with an explanation, and you can choose the cognitive level. Every question has one correct answer, so there is no select-all-that-apply. If your exam uses fill-in-the-blank or matching items, Questgen is the better match for that format.
Exporting quizzes to Canvas, Moodle and other LMSs
Both export the two formats most LMSs import. QuerySpark exports QTI (for Canvas, Blackboard and D2L) and Moodle XML, plus PDF, Word, plain text, Markdown, CSV and JSON. Flashcard decks export as CSV, which Anki and Quizlet can import.
Questgen covers more targets: QTI 2.1, Moodle XML, GIFT, Aiken and Respondus text, PDF with or without answers, JSON, and CSV files formatted for D2L Brightspace, Gimkit, TriviaMaker and Quizizz. If your platform only takes GIFT, Aiken or Respondus, use Questgen or convert from QuerySpark's plain text yourself.
Inside QuerySpark
Questions you study from, not just export
Answer one at a time. Every answer is explained, usually with the line from your material it came from, and the ones you miss come back until they stick.
Can you study with the questions, or only export them?
You can study in both, but QuerySpark is built around it. Questgen has a Study mode where you answer the generated quiz and see a score at the end. In QuerySpark you answer one question at a time, read the explanation, and on most questions see the passage from your own material the question was written from. Missed questions come back, flashcards are scheduled with spaced repetition, and practice tests give you a score.
For teachers, QuerySpark adds classes with a join code, assignments and per-student progress and scores, which matters if you want students to practise inside the tool rather than in your LMS.
Inputs: PDFs, slides, videos and YouTube links
Both accept the usual course material, with a few differences worth checking before you pick one:
- Questgen: pasted text up to 80,000 words, web URLs, PDF, Word (DOCX), images, and audio or video files. For YouTube, its site suggests saving the video as an audio file and uploading that.
- QuerySpark: PDF up to 100 MB and 120 pages per upload with scanned pages read by OCR, Word, PowerPoint, photos of notes including neat handwriting, recordings up to 25 MB, web articles, pasted text, and YouTube links directly (videos need captions or a transcript).
- Set size: a QuerySpark run usually produces 10 to 20 questions in about a minute. Questgen says it can produce up to 150 quizzes from 100,000 words in one go, which suits building a large question bank.
The Questgen GitHub library vs the Questgen app
They are different things. The Questgen.ai repository on GitHub is an open-source, MIT-licensed Python library for question generation that developers run on their own machines. The hosted app at questgen.ai is the product with the plans, Study mode and export formats described on this page. If you want to generate questions from your own code, the library is the relevant option; QuerySpark is a web app and does not offer a developer library.
When to choose each
When to Choose QuerySpark
- You are studying the material yourself. One upload gives you practice questions, flashcards with spaced repetition and a study guide, and the questions you miss come back until you get them right.
- You want to try the full product without a card. The 3-day Pro trial needs no credit card and leads into a limited free plan with 1 study session a month.
- You want quizzes and flashcards from the same source. Generate both from one PDF, slide deck or YouTube lecture and switch between them.
- You want essay questions or a class to assign to. QuerySpark writes essay prompts alongside MCQ, true/false and short answer, and teachers can run classes with a join code and track each student.
When to Choose Questgen
- You need question formats QuerySpark does not make. Questgen lists fill-in-the-blank, matching and multiple-answer MCQs. QuerySpark questions always have exactly one correct answer.
- You export to many different systems. Besides QTI and Moodle XML, Questgen exports GIFT, Aiken and Respondus, plus CSV files laid out for D2L Brightspace, Gimkit and Quizizz.
- You build assessments at volume. Questgen takes up to 80,000 words of input per run and its Pro plan offers unlimited runs under a fair use policy.
- You want one flat price. Questgen has a single paid plan at $15 a month or $100 a year, with no tiers to choose between.

It depends on where the questions end up. If you export to an LMS and need fill-in-the-blank, matching or multiple-answer items, or formats like GIFT and Aiken, Questgen fits better. If you want students to practise in the tool with classes, assignments and per-student scores, QuerySpark fits better.
QuerySpark is built for that case: questions come with explanations and usually the source passage, missed questions come back, and flashcards use spaced repetition. Questgen has a Study mode with a score, but its focus is on creating and exporting assessments.
Yes. QuerySpark exports QTI for Canvas, Blackboard and D2L and Moodle XML, as well as PDF, Word, text, Markdown, CSV and JSON. It does not export GIFT, Aiken or Respondus, which Questgen does.
No. QuerySpark makes multiple choice, true/false, short answer and essay questions, and each has exactly one correct answer. Questgen is the better choice if you need fill-in-the-blank, matching or multiple-answer formats.
Yes. Questgen can generate questions for a specific Bloom's level or across all six. QuerySpark lets you choose the cognitive levels when you generate a set.
No. The GitHub repository is an open-source Python library for developers. The website is the hosted app with plans, Study mode and exports. The library does not give you the hosted app's interface.
