Quiz Generator

Turns your notes into fill-in-the-blank questions by removing the rarest word in each sentence, so the answer is always a term you have to know rather than “the” or “of”.

Fill in the blank

Generated from your material

It blanks the word that carries the meaning

The word removed is the rarest one in the sentence, because removing “the” tests nothing. Rarity is the same signal that makes a term a keyword in the first place.
Why use it

Built to be genuinely useful

Rarest word, not any word

Each question drops the least common word in its sentence, which is the word carrying the actual claim.

Ranked against your text

Frequency is counted across the whole document you paste, not taken from a generic English word list.

Answers kept alongside

Every blank keeps its missing word, so you can mark yourself without hunting back through the notes.

Nothing is uploaded

Everything runs in your browser, so your notes never reach a server.

How it works

Three steps

  1. 1

    Paste a chapter, transcript or page of notes.

  2. 2

    Read the questions it builds, one per usable sentence.

  3. 3

    Fill the blanks from memory, then check the answers.

Why the rarest word is the right blank

Most cloze tools remove a word at a fixed interval — every seventh word, say. That gives you questions like “The mitochondrion is ___ site of oxidative phosphorylation”, where the answer is “the”. You can fill that in from grammar alone, without having read a line of the chapter, so the question measures nothing.

Rarity fixes that. Across a page of biology notes, “the” might appear forty times and “phosphorylation” twice. The word that appears twice is the one carrying the specific claim of the sentence, and it is the one that goes missing in the exam hall. Blank that, and the question has something to test.

This is the same statistic that decides which words count as keywords in a document: terms that are frequent in this text and rare in ordinary writing. Running it over your notes produces blanks for terminology, proper nouns, dates and quantities — close to what the short-answer sections of most Indian university papers ask for.

What the tool will not do

There is no language model behind this. The tool splits your text into sentences, counts how often each word occurs across the whole document, and removes one word per sentence. It cannot invent a question that was not already in your text, rewrite a clumsy sentence, or notice that your notes have skipped half the syllabus.

That is worth knowing before you lean on it. A quiz built from a thin summary will be a thin quiz, because every question is one of your own sentences with a hole in it. Paste the chapter, the lecture transcript or the full set of notes rather than the three lines you wrote afterwards.

The compensation is that the process is deterministic. The same text always produces the same questions, so you can generate a quiz today, sit it again in ten days, and compare two scores that came from an identical paper. A tool that writes fresh questions each time cannot give you that.

Using it without fooling yourself

Recognition is not recall. A sentence with one word missing still hands you the surrounding context, so filling the blank is easier than reproducing the idea on blank paper. Scoring well here means the material is fresh, not that you could answer a five-mark question on it tomorrow morning.

The better use is spacing. Generate the quiz the day you make the notes, sit it three days later, then a week after that. Any blank you miss twice is a topic to write out longhand rather than reread — two misses is a far more reliable signal than a vague feeling of not knowing something.
