If you’ve tried a few AI tools for reading comprehension, you already know the problem.

Most of them can generate something but very few generate questions you’d actually use without fixing, rewriting, or reformatting.

- You might have one tool that’s fast but shallow.
- Another that’s flexible but takes too much prompting.
- And maybe one that looks promising until you try to reuse the questions for another class.

This guide isn’t about whether AI can help with reading comprehension - you’ve already crossed that bridge. It’s about which tools are actually worth keeping in your workflow.

We reviewed the most commonly used AI question generators and compared them side by side: how they handle real classroom materials, how much control you get, and how usable the output really is. 

The goal is simple: help you decide which tool fits how you teach, and which ones aren’t pulling their weight anymore.

How did we Evaluate AI Reading Comprehension Question Generators? (And you should too!)

There are plenty of AI tools that can technically generate questions. That doesn’t mean they work well in a real classroom.

So instead of judging tools based on flashy features or vague promises, we evaluated them the same way a teacher would use them during lesson prep with actual materials, real time constraints, and realistic expectations.

Here’s what we measured to find the best AI question generators:

1. Can you create questions from the materials you already use?

Most teachers aren’t starting from scratch. You already have:

  • PDFs
  • Reading passages
  • Articles
  • Videos
  • Notes or worksheets from previous years

We checked whether each tool could generate reading comprehension questions directly from these materials, without forcing teachers to rewrite or reformat content first. 

2. Are the questions actually useful for students?

Not all AI-generated questions are equal. We looked at whether the questions:

  • Made sense for the passage
  • Went beyond “what happened” style recall
  • Helped check real understanding

If the output felt like something a teacher would immediately rewrite, that mattered. If the questions could realistically be used for a quick comprehension check, discussion, or assessment, that's a plus.

3. How much control does the teacher really have?

Classrooms aren’t one-size-fits-all.

We evaluated whether teachers could:

  • Choose question types (like MCQs or short answers)
  • Adjust difficulty
  • Reuse the same passage for different levels of students

If a tool forced the same output every time with no way to tweak it, that limited its usefulness. Tools that gave teachers clear, simple controls scored higher.

4. Can the output be used right away?

Some tools generate text that still needs a lot of work before students ever see it. We checked whether questions:

  • Were already structured clearly
  • Could be turned into a worksheet or quiz easily
  • Needed heavy formatting or rewriting

If a teacher could realistically use the output the same day, that mattered.

5. How much effort does it take to get good results?

AI is only helpful if it saves time. We paid attention to:

  • How many steps it took to generate questions
  • Whether prompt writing was required
  • How intuitive the workflow felt

If a tool took longer than writing questions manually, that was a red flag. Tools that worked quickly without much setup ranked higher.

6. Who is the tool actually meant for?

Instead of asking “Which tool is best?”, we asked: “Which teacher is this best for?”

Some tools are great for:

  • Quick comprehension checks
  • Close reading discussions
  • Differentiated instruction
  • Full quizzes and assessments

We made sure each review clearly explains who will benefit, and who probably won’t.

Top 7 Reading Comprehension Question Generators 

Here are the best reading comprehension question generators based on our research:

Monsha: The Best AI Reading Comprehension Question Generator

Monsha’s reading comprehension question generator is designed around assessment creation, not casual AI use. It generates reading passages and questions for them.

Instead of asking teachers to figure out prompts or formats, it guides them through a structured flow that’s similar to how you design quizzes and tests in real classrooms.

This makes a lot of difference when you’re working under time pressure and need something usable, not experimental. The reading comprehension questions you generate are not one-time-use, you can create any resource you want from them.

What makes Monsha the best AI reading comprehension question generator?

Create questions from any source material 

In a real classroom, teachers rarely start from a blank page. You might be working with a chapter PDF, a newspaper article, Youtube video, or simple text to create comprehension questions. Monsha allows you to bring in these existing materials directly, instead of rewriting or copying them into a new format.

💡
You can also generate reading comprehension questions from existing files. Read this blog to understand the process: How to generate reading comprehension questions from a file using AI?
Have full control of the questions your want

With Monsha, you can select the source, number of questions, type of questions, grade level, language and framework. 

You can generate MCQs, fill in the blanks, true/flase, essay questions and much more in Monsha. Its AI question generator understands the passage and pulls in-depth questions, instead of simple MCQs.

Also, the Monsha question generator is quite intuitive. For example, you can generate questions for a nonfiction article to check its interpretation and meaning, not just “what happened.” So, although AI generated, your questions are deep and impactful.

Create differentiated questions for different students 

Sometimes, you need simpler questions for one class and more challenging ones for another, without starting over each time. To achieve this, you simply select ‘adapt to framework’ and choose what you want to adjust - Depth of Knowledge, Lexile reading levels, Bloom’s Taxonomy.

Monsha is the best tool to create differentiated resources whether they’re worksheets, presentations or reading comprehension questions.

Questions are always ready to use 

Many AI tools generate text that still needs formatting, restructuring, or rewriting before it can be used with students. 

Monsha’s outputs are already shaped like quizzes or assessments, which you can use immediately. 

If you’re preparing an exit ticket or a short comprehension check, this saves significant time. You can export questions as Google Docs, Google Forms, DOCX, PDF or even share to Google Classroom.

Edit questions easily 

Monsha has an easy to use editor right inside the app. You can change text, layout, or add images and tables to your document. You also get a prompt bar where you can chat with the editor and tell it what you want to change and it will implement those changes immediately.

Best for:

Monsha is best for teachers who:

  • Create quizzes or comprehension checks from passages, PDFs, or articles
  • Teach ELA, social studies, or content-heavy subjects
  • Want classroom-ready questions with minimal editing

Smallpdf Question Generator

Smallpdf’s question generator is basically a tool that allows you to work with PDFs - compress them, edit them, sign them etc. It’s also positioned itself as an AI question generator from PDF.

What makes the Smallpdf Question Generator a good AI reading comprehension question generator?

Create questions directly from PDFs

In many classrooms, reading materials are shared as PDFs - textbook chapters, scanned worksheets, or downloaded articles. Smallpdf allows teachers to upload those PDFs and generate questions from it without copying the text into another tool.

Works as a simple AI question generator

Smallpdf functions well as a general AI question generator, especially for basic comprehension checks. It typically produces questions that focus on key ideas and facts from the document.

For example, if you upload a short informational passage, you’ll get a usable set of questions that reflect the main points. 

That said, the questions tend to stay surface-level and may need refinement if you’re aiming for deeper analysis or higher-order thinking. It’s more about speed than instructional depth.

Generate variety of questions 

You can generate MCQs, true/fasle and open ended questions. It works well if you’re looking to quickly generate questions one time and don’t need to connect them to a course. 

Works with iOS

Smallpdf is one the few AI reading comprehension question generators that work on any device including iOS, Android, Mac, Windows and Linux -check.

Best For

Smallpdf is best for teachers who:

  • Want to generate questions directly from PDFs
  • Need a quick comprehension check with minimal setup
  • Prefer a simple, free AI question generator
  • Are comfortable editing questions manually afterward

It may be less suitable if you:

  • Need differentiated or higher-order comprehension questions
  • Want control over question types or difficulty
  • Create assessments frequently and need reusable outputs
  • Expect classroom-ready formatting without extra work

Pricing

  • Free: Limited usage
  • Paid plans: Vary based on Smallpdf subscription tiers

NoteGPT

NoteGPT is an all-in-one learning assistant that works for both students and teachers. It has specific features around PDFs and one of them in an AI quiz generator from PDFs. Like Smallpdf, NoteGPT also only works with PDFs or pasted text.

What makes the NoteGPT a good AI reading comprehension question generator?

Generate questions from PDFs

NoteGPT is centered around PDFs so you can either upload a PDF or paste text to generate quiz-style questions. This makes NoteGPT a practical AI question generator when you have limited time. 

Choose difficulty level

You can select how difficult you want your questions to be. This comes in handy when you’re creating questions for students with learning difficulty.

  • Pro: $9/month
  • Unlimited: $14
  • Max: $49

OpenAI ChatGPT 

ChatGPT works as a general-purpose AI question generator rather than a dedicated reading comprehension or assessment tool. You can use it to generate questions from pasted text, passages, or documents by prompting it directly. 

What makes the ChatGPT a good AI reading comprehension question generator?

Generate questions from pasted text or passages

Paste a reading passage or text and ask the AI to generate comprehension questions from it. This is useful when you already have the content and want to quickly draft questions without using a separate tool. 

💡
If you want the best output from ChatGPT, here are the best AI prompts you can use . These prompts are curated specially for teachers.
Control question type and difficulty through prompts

One real advantage of ChatGPT is that teachers can explicitly ask for certain question types or difficulty levels. For example, you can prompt it to generate MCQs, short-answer questions, or higher-level thinking questions, and specify whether they should be easy, moderate, or challenging. 

Works best when teachers already know what they want

ChatGPT is most effective for teachers who are comfortable guiding AI with specific instructions. If a teacher knows exactly what kind of questions they want, ChatGPT can produce them quickly. 

Create Custom GPTs to avoid prompting

If you don’t like prompting, you can create custom GPTs to create comprehension questions. Then, you won’t have to rewrite the same prompts again. Once you customize your GPT, you can just upload your passage and it will generate questions for you.

Best For

ChatGPT is best for teachers who:

  • Want to generate questions from pasted text quickly
  • Are comfortable writing clear prompts
  • Need flexibility in question type and difficulty
  • Use AI mainly for drafting, not final assessments

It may be less suitable if you:

  • Want classroom-ready quizzes or worksheets
  • Prefer guided workflows instead of prompt writing
  • Need reusable, structured assessment outputs
  • Rely on file-based inputs like PDFs regularly

Pricing

  • Free: Limited access
  • Paid: ChatGPT Plus / Team plans with higher limits and models

NotebookLM 

NotebookLM can also act as an AI question generator. The best part is, all your questions are grounded strictly in those sources. However, everything is driven through prompts and artifacts, not preset classroom workflows.

What makes the ChatGPT a good AI reading comprehension question generator?

Generate questions using multiple source types

Just like in Monsha, you can upload PDFs, videos, images, ebooks, and text documents to NotebookLM and it will use everything as the source. This is useful when a lesson pulls from more than one resource, such as a chapter reading plus a video explanation. 

You can then ask the AI to generate comprehension questions that reference all uploaded materials together. 

Create differentiated questions from the same passage

NotebookLM can generate different sets of questions from the same source material by prompting it for varying depth or focus. You can ask for simpler comprehension questions first, then request more analytical or discussion-based questions from the same passage. 

Turn comprehension questions into worksheets

NotebookLM can convert AI generated questions into structured study materials such as worksheets or study guides. For example, after generating comprehension questions, you can ask the tool to format them into a printable worksheet or organized handout. 

However, these worksheets are text-based and still require review before classroom use. The tool helps assemble the content, but you still have to edit them as per your teaching style.

Generate visuals and infographics to support comprehension

One standout capability of NotebookLM is its ability to generate visual summaries and infographic-style representations related to the content and questions. You can ask it to create diagrams, concept breakdowns, or visual explanations that support comprehension questions. 

For instance, you can ask it to create a diagram-based question where students have to refer to the image to answer questions.

Best For

NotebookLM is best for teachers who:

  • Use multiple content formats (PDFs, videos, ebooks, images)
  • Want questions grounded strictly in source material
  • Are comfortable shaping outputs through follow-up instructions

It may be less suitable if you:

  • Want ready-made quizzes or assessments
  • Prefer guided, teacher-first workflows
  • Need built-in question type or difficulty selectors
  • Create graded assessments frequently

Pricing

  • Free: Available with a Google account (usage limits may apply)

MagicSchool AI 

MagicSchool AI is built specifically for teachers and classroom workflows. Its multiple-choice quiz and assessment tool that generates structured questions quickly without writing prompts.

What makes the MagicSchoolAI a good AI reading comprehension question generator?

Generate multiple-choice questions from text or topics

MagicSchool AI lets you generate multiple-choice questions by entering a topic or pasting text. This works well when you want quick comprehension or recall-based questions from a reading passage. 

For example, you can paste a short article and instantly create MCQs to check understanding at the end of a lesson.

Choose grade level and question difficulty

One of MagicSchool’s strongest features is built-in control over grade level and difficulty. You get to specify whether questions should be simpler or more challenging, which is helpful when teaching the same content across different classes

Built-in exemplars reduce prompt writing

MagicSchool AI includes sample outputs and an exemplar-driven workflow. You don’t need to figure out how to “ask the AI correctly” to get usable results. You fill in a few fields, review the generated questions, and adjust if needed. This is great for teachers who are new to AI or don’t want to spend time refining prompts. 

Questions are ready for classroom use

The multiple-choice questions generated by MagicSchool are formatted clearly and don’t require heavy restructuring. You can use them directly for quizzes, exit tickets, or formative assessments. 

Best For

MagicSchool AI is best for teachers who:

  • Create multiple-choice quizzes regularly
  • Want built-in grade and difficulty controls
  • Prefer guided inputs over open-ended prompting
  • Need quick, classroom-ready assessment questions
  • Are new to using AI in teaching

It may be less suitable if you:

  • Want deep customization or framework-based controls
  • Build reusable assessment systems

Pricing

  • Free: Limited access
  • Plus: $8.33
  • Enterprise: Custom

Flint

Flint’s Text-Dependent Question Generator is built specifically for standards-aligned reading instruction. The tool focuses on generating questions that require students to refer directly to the text, rather than relying on background knowledge or opinion.

What makes Flint a good AI reading comprehension question generator?

Generate text-dependent questions from passages

In Flint, you paste a reading passage and generate questions that explicitly reference details, ideas, and evidence from that text. It’s great to test close reading skills, where students must justify answers using the passage itself. 

For example, an ELA teacher can input a short story or nonfiction excerpt and receive questions that push students to cite specific lines or ideas. The questions stay grounded in the text rather than drifting into generic comprehension prompts. 

Create questions aligned to instructional rigor

Flint is useful when you want students to actually look at the passage again instead of guessing or answering from memory. You can use the same text to generate simpler questions first, then ask for questions that make students explain why something happened or point to evidence. 

For example, you might start with “What does the author say here?” and then move to “Which line in the text supports this idea?” This makes it easier to plan lessons that slowly build comprehension instead of jumping straight to hard questions. You decide how deep the questions go based on how you use the tool.

Designed for close reading and classroom discussion

The questions Flint generates are well suited for guided reading, small-group discussion, or whole-class analysis. You can use them to prompt discussion where students must return to the text to support their answers. 

Simple workflow

Flint keeps the workflow simple: input the text, generate questions, review, and use. There’s no need for prompt engineering, which lowers the barrier for everyday classroom use. 

However, the tool is focused narrowly on text-dependent questions rather than offering multiple assessment formats. It works best when that specific instructional need is clear.

Who Is This Tool Best For?

Flint is best for teachers who:

  • Teach ELA or reading-intensive subjects
  • Focus on close reading and evidence-based answers
  • Want text-dependent questions grounded in passages
  • Use questions for discussion or guided reading
  • Prefer a simple, teacher-first AI workflow

It may be less suitable if you:

  • Need multiple question formats (MCQs, essays, quizzes)
  • Want assessment-ready exports
  • Rely heavily on PDFs or multimedia inputs
  • Build reusable quizzes or tests frequently

Pricing

  • You can generate some questions for free
  • Up to 150 users: $3000/year
  • Up to $250 users: $4000/year
  • Up to 500 users: $6500/year
  • Over 500 users: Custom pricing

Final Verdict - Which AI Reading Comprehension Question Generator is the Best?

Once you step back and look at these tools side by side, the difference isn’t about intelligence or output quality. It’s about what happens after the questions are generated.

Most tools stop at generation. Monsha doesn’t.

With Monsha, reading comprehension questions aren’t a dead end. You can adapt them for different students, reuse them across classes, and turn them into quizzes, worksheets, Google Forms, or presentations without rebuilding everything from scratch. That matters when reading comprehension is something you do every week, not once in a while.

Other tools still have a place. Some are great for quick checks. Others work well for close reading or content exploration. And a few are useful when you just want ideas fast. But they all require you to stitch together the rest of the workflow on your own.

Monsha is the only tool in this list that treats reading comprehension as part of a system, not a single task. It’s built for teachers who want consistency, reuse, and control without spending extra time formatting, rewriting, or starting over.

If reading comprehension questions are a regular part of your teaching, Monsha isn’t just the best option here, it's the one that actually holds up over time.

And it’s completely free to use.

FAQs: AI Reading Comprehension Question Generators

What is an AI reading comprehension question generator?

An AI reading comprehension question generator is a tool that creates questions based on a passage, PDF, article, or other learning material. Teachers use it to quickly check whether students understood what they read, instead of writing questions from scratch. Some tools only generate basic recall questions, while others support deeper comprehension and reuse across classes.

Can AI generate reading comprehension questions from PDFs?

Yes. Many tools now work as an AI question generator from PDF, allowing teachers to upload chapters, worksheets, or articles and generate questions directly from them. This is especially helpful when your reading material already exists as a document. Tools like Smallpdf focus purely on PDFs, while platforms like Monsha allow you to generate questions from PDFs and then reuse them across quizzes, worksheets, or forms.

Are free AI question generators good enough for teachers?

Free AI question generators are usually good for quick or occasional use. They can help with discussion starters, homework checks, or informal comprehension questions. However, most free tools require manual editing, formatting, or rewriting if you want to reuse questions across classes. Teachers who generate reading comprehension questions regularly often need more structure than free tools provide.

Can ChatGPT be used as a reading comprehension question generator?

Yes, ChatGPT can work as an AI question generator if you paste a passage and ask it to generate questions. It’s flexible and works well when you know exactly what to ask for. However, it doesn’t provide built-in controls, classroom-ready formats, or reuse options. Many teachers use ChatGPT for drafting ideas, then move questions into another tool or document for actual classroom use.

What’s the difference between an AI question generator and an assessment tool?

An AI question generator usually focuses on producing questions from text. An assessment tool goes further, helping teachers organize those questions into quizzes, worksheets, or tests that can be reused or shared. This difference matters if reading comprehension is part of your weekly teaching routine. Some tools stop at generation, while others support the full assessment workflow.

Can AI tools create differentiated reading comprehension questions?

Some AI tools allow basic difficulty selection or prompt-based variation, which helps create easier or harder questions from the same passage. More advanced tools support differentiation by adjusting reading level, depth of thinking, or instructional framework. This is useful when the same text needs to work for multiple groups of students. Not all tools support this equally, so it’s worth checking before committing.

What is the best AI reading comprehension question generator for regular classroom use?

The best tool depends on how often you create comprehension questions and how much reuse you need. If you only need quick, one-off questions, simpler AI tools may be enough. If you regularly build quizzes, worksheets, or assessments and want to adapt questions for different students without starting over, a teacher-first platform like Monsha tends to fit better into long-term classroom workflows.

Do AI-generated comprehension questions need teacher review?

Yes. Even the best AI reading comprehension question generators should be reviewed before classroom use. Teachers need to check clarity, alignment with learning goals, and appropriateness for their students. The value of a good tool is not that it replaces teacher judgment, but that it reduces the time spent on drafting, formatting, and rebuilding questions.
