An AI quiz generator writes the questions. You check the answer key.
An AI quiz generator turns a topic, your notes or a document into multiple-choice questions with the right answers already marked. That last part is the risk: a model marks a wrong answer as correct with the same confidence as a right one. This guide covers which AI quiz makers accept text or PDFs, how to verify an answer key quickly, and how to set up scoring so the results mean something.

What does an AI quiz generator do?
An AI quiz generator drafts quiz questions from a prompt or source material, writes answer options and marks the correct ones, then hands you an editable quiz. Some tools accept PDFs and slides; others, including Zunoform, take typed text only. In every case the answer key must be checked by a person before the quiz is shared, and scoring rules such as points and pass marks should be set deliberately rather than left at defaults.
- From PDF: Google Forms with Gemini (eligible plans), Jotform, Smallpdf.
- From text: all of them, including Zunoform (up to 2,000 characters).
- Zunoform's AI generator is on the Business plan at $24.99/month; quiz scoring itself is free on every plan.
Which AI quiz makers work from a PDF or from text?
Taken from each vendor's own pages on 28 September 2026.
| Tool | Input it accepts | What you get back | Plan notes |
|---|---|---|---|
| Google Forms (Gemini) | A prompt, or Drive files including Docs, Sheets, Slides and PDFs | A Google Forms quiz with correct answers and points set | Eligible Google Workspace or Google AI plans; desktop only; generating replaces the current form |
| Jotform AI Quiz Generator | A prompt, or a PDF, PowerPoint, Word or text file up to 10 MB | A Jotform quiz you edit in its form builder | Free Starter plan: 5 quizzes (5 active forms), 100 submissions per month |
| Smallpdf AI Question Generator | PDF, Word, Excel, PowerPoint and image files | Questions and answers to download, not a hosted quiz that collects responses | Free without signup; an account adds a 7-day trial |
| Zunoform | A typed description of 10 to 2,000 characters; no file upload | A hosted quiz with correct answers marked, scoring on and a results screen | Business plan only, $24.99/month; 10 generations per hour |
Smallpdf is a document tool rather than a quiz platform: you would still need a form builder to collect and score answers.

Can Zunoform make a quiz from a PDF?
Not directly. Zunoform's AI quiz maker reads a typed description only: no PDF, slide or image upload, and the description is capped at 2,000 characters, which is roughly 300 words of English. If your source is a long PDF, you have three honest options.
Paste the part that matters
Copy the section you want to test, such as one chapter summary or a list of key terms, into the prompt and say how many questions you want from it. Short, dense source text produces better questions than a whole document anyway, because the model has less room to wander.
Import a question file
The builder's Import questions option reads .txt, .csv and .md files up to 200 KB and 100 questions. In a text file, each question sits on its own line and bulleted lines beneath it become the answer choices. If you already have questions, from a textbook, a colleague or another tool that reads PDFs, this gets them into Zunoform without the AI. The import carries questions and options but not the answer key, so you mark correct answers in the builder afterwards, which doubles as your review pass.
Use a PDF-reading tool instead
If drafting from a PDF is the whole job, Google Forms with Gemini or Jotform's generator will do it in one step, as the table above shows. That is a fair reason to choose them over Zunoform for this task.
What does Zunoform's AI quiz generator produce?
Ask for "a 10-question multiple-choice quiz on fractions for year 6, four options each, mixed difficulty" and the generator returns choice, multi-select or dropdown questions with the correct options marked, a welcome screen and a themed design. Quiz scoring is switched on, and the results screen is set to show the score and an answer recap.
Two safeguards run before anything is saved. A correct-answer mark only survives if it matches one of the question's options exactly, so a mismatch shows up as an unmarked question in the builder rather than silent wrong grading. Point values are clamped to a sane range. What the generator does not do is fact-check itself, set grade boundaries (the list comes back empty, which means the default A+ to F scale applies) or decide your pass mark.
How do you check an AI-generated answer key?
Budget about a minute per question. It is still much faster than writing the quiz yourself.
Verify every marked answer against your source
Open the PDF, textbook or notes next to the builder and confirm each correct option. If you cannot find the answer in the source, delete the question instead of trusting the model's memory.
Check for more than one defensible answer
Models write options that are right in some contexts. If a knowledgeable learner could argue for a second option, reword the question or the option until only one is correct.
Rewrite weak distractors
Wrong options that are obviously wrong let people pass by elimination. Replace them with mistakes a learner would plausibly make, such as a common misconception or a near-miss number.
Look at multi-select questions separately
In Zunoform a multi-select question counts as correct only when the respondent picks exactly the marked set. Make sure the question says "select all that apply" and that the marked set is complete.
Take the quiz as a respondent
Answer some questions right and some wrong, then compare the score on the results screen with the score stored on the response. They are computed from the same rules, so a difference means something is misconfigured.
How should you set up quiz scoring?
Scoring is where a quiz's purpose lives, and none of it needs the AI. In Zunoform every scoring feature is available on every plan, including Free with 500 responses a month.
Scoring decisions to make yourself
Points per question
Without custom points, each marked question is worth one point. Give harder or more important questions more weight with per-option points, and use negative points if you want guessing to cost something.
Partial credit
Right-or-wrong marking on a multi-select is all or nothing. If you want partial credit, assign points to each correct option instead, so every right pick adds to the total.
Grade bands and pass marks
Left empty, grades follow the default A+ (97%) to F scale. For a training check you may want a single pass band at 80%; for a lead-generation quiz, named tiers. Decide before the first results come in.
What the taker sees
Score, grade, an answer recap that reveals the right answer only for questions they missed, per-question explanations, or a different ending screen for each score range. A personality quiz may show only an outcome and no score.
Is the answer key visible to people taking the quiz?
For most quizzes, no. When results are revealed only at the end, Zunoform removes correct answers, option points, explanations and custom grade bands from the form sent to respondents; the score is calculated on the server at submission, so editing the page in a browser does not change the stored result.
The exception is a quiz that shows or acts on the score mid-form, for example by putting the running {{score}} into a question, or using score in a logic rule to branch. Then the key has to be sent to the browser so the form can calculate as it goes. The builder's Score quiz dialog tells you which case your form is in.
Be clear about the limits as well. Zunoform has no quiz timer and no proctoring, and someone can learn answers by resubmitting unless you turn on one response per person. Use it for practice quizzes, knowledge checks, training and lead-generation quizzes, not for high-stakes exams.
A prompt for an AI quiz from your own text
Create a 10-question multiple-choice quiz to check understanding of the text below. Use only facts stated in the text; do not add outside information. Four options per question, one correct answer, and make the wrong options plausible mistakes rather than obvious ones. Mix recall questions with two questions that ask the reader to apply an idea. Show the score at the end. Text: [paste up to about 250 words here]
Zunoform's limit is 2,000 characters for the whole prompt, so keep the instructions short and leave most of the room for the source text.
Before you share the quiz
- Every correct answer verified against the source material.
- No question with two defensible answers.
- Distractors rewritten so elimination alone does not pass the quiz.
- Multi-select questions say "select all that apply" and have a complete answer set.
- Points, negative marking and partial credit decided on purpose.
- Grade bands or a pass mark set, not left to the default by accident.
- Results screen chosen: score, grade, recap, explanations or outcome endings.
- One response per person turned on if repeat attempts would spoil the results.
- A full test run completed on a phone.
Where Zunoform fits (and where it doesn't)
Zunoform suits quizzes you want to host and score: knowledge checks, training quizzes, trivia and lead-generation quizzes with different result screens by score range or by answer. Scoring, grades, explanations and outcome endings are free on every plan. The AI generator that drafts questions is Business-only at $24.99/month, reads typed text rather than files, and allows 10 generations an hour.
It is the wrong choice if you need to turn PDFs into quizzes in one step (Google Forms with Gemini or Jotform read files), need timed or proctored exams (Zunoform has neither), or want AI drafting free of charge. For building by hand, start from the trivia quiz, personality quiz or product recommendation quiz templates.

Questions people ask
Can AI make a quiz from a PDF?
Yes, with tools that read files. Google Forms with Gemini drafts quizzes from Drive files including PDFs on eligible plans, Jotform's generator accepts PDF, Word, PowerPoint or text files up to 10 MB, and Smallpdf produces a downloadable question list. Zunoform's generator does not accept PDFs; paste the relevant text into the prompt instead.
Is there a free AI quiz generator?
Jotform's AI quiz generator works on its free Starter plan, which allows 5 forms and 100 submissions a month, and Smallpdf's question generator is free without signup. Zunoform's AI generator is not free: it requires the Business plan at $24.99/month. Building and scoring quizzes by hand in Zunoform is free.
How accurate are AI-generated quiz answers?
Accurate enough to save time, not accurate enough to skip checking. Models can mark a wrong option as correct, write two defensible answers, or add facts that are not in your source. Verify every marked answer against the material you are testing, and delete any question you cannot confirm.
Can I make an AI quiz from my notes?
Yes. Paste the notes into the prompt and tell the generator to use only facts from that text. In Zunoform the prompt limit is 2,000 characters, so work through long notes one section at a time, or write your questions in a text file and use Import questions.
Do I need a paid plan to score a quiz in Zunoform?
No. Correct answers, per-option points, grade bands, explanations, answer recaps and outcome endings by score range are available on every plan, including Free with 500 responses a month. Only the AI that drafts the questions needs the Business plan.
Can quiz takers see the answers in the page code?
Not for quizzes that reveal results at the end: Zunoform strips correct answers and points from the public form and scores on the server. If the form displays the running score mid-quiz or branches on it, the key is sent to the browser. The Score quiz dialog tells you which applies.
Can I add a time limit to an AI-generated quiz?
Not in Zunoform: there are no quiz timers or proctoring. You can close the form on a date or after a number of responses, and limit people to one response each. For timed exams, use a dedicated assessment tool.
