Fill-in-the-Blank Generator

A fill-in-the-blank exercise (also called a cloze test, cloze exercise or gap fill) is an activity where a text is taken and certain words are hidden, replaced by blank spaces. The student must write the correct word using the context of the text and, optionally, a word bank as a guide. It is one of the most versatile exercises in education because it works reading comprehension, vocabulary, grammar and content retention in any subject and level. You can create your own exercise in seconds with this tool.

With this generator it is very simple: paste or write the base text, select the words you want to hide (manually or automatically) and click 'Generate exercise'. The tool automatically creates the blank spaces and the word bank. You can activate interactive mode so students answer on screen, or print the exercise on paper. No sign-up or download is needed; everything runs directly in the browser.

The cloze test is the technical name for the fill-in-the-blank exercise. Unlike a question-and-answer quiz, the cloze test maintains the narrative context of the paragraph, which forces the student to read carefully to infer the correct word. This makes it a particularly effective instrument for assessing genuine reading comprehension, not just memorization. It is also called gap fill or fill in the blank depending on the context or pedagogical tradition.

In manual mode, the teacher clicks directly on the words in the text to choose which ones will be hidden. This gives full control to select key terms, specific concepts or difficult words you want to assess. In automatic mode, the tool selects one out of every N words based on the frequency slider, ignoring short words of three letters or fewer so the exercise makes sense. Manual mode is ideal when you want a precise exercise; automatic mode is perfect for generating quick reading activities without extra configuration.

For elementary school, the best approach is to use manual mode and select only the most important words in the text, keeping the blanks at a low ratio (between 1 and 3 words per sentence). Activate the word bank to make the exercise more guided and accessible. Use short texts, between 50 and 150 words, with vocabulary appropriate for the level. The tool has no length limit, but short texts work better for elementary. Once generated, you can print the exercise directly as PDF.

Yes, it is especially useful for language arts and grammar. You can manually select the verbs, determiners, prepositions or connectors in the text to create exercises focused on a specific grammatical category. For example, hide all conjugated verbs to practice verb tenses, or select connectors to work on textual cohesion. It also works for spelling exercises if the text includes words with specific difficulties you want students to recall and write correctly.

Yes. The tool works with any language because it processes the text exactly as you write it: it does not analyze or process the language, it simply hides the words you select. You can create fill-in-the-blank exercises in English, Spanish, French, German, Portuguese or any other language. It is ideal for practicing vocabulary, grammatical structures or phrases in context. The word bank appears in the same language as the text, making the exercise fully coherent for the student.

The word bank is a list of the hidden words, shown in random order below the text, that serves as support for the student. You can activate or deactivate it with a simple switch. With a word bank, the exercise is more guided and accessible: the student reads the context and chooses from the given options, making it suitable for beginner levels or when the goal is comprehension. Without a word bank, the exercise is more demanding because the student must recall or infer the word correctly, which better works retention and active vocabulary.

When interactive mode is activated, the blank spaces become text fields where the student can type directly on screen. When the student presses 'Check', each field is marked green if the answer is correct or red if it is incorrect. Grading is instant and requires no internet connection because everything runs in the browser. This mode is ideal for using the tool projected in class, on individual tablets or in a computer lab. Interactive mode and the printable version are independent: you can use both depending on the situation.

Yes. The 'Print / Save PDF' button opens the browser's print dialog, which in all modern browsers (Chrome, Firefox, Edge, Safari) allows saving the result as PDF. The printed version has a clean design with no interface elements: only the title, the instruction, the text with blank spaces and the word bank if activated. It is perfect for distributing to students on paper or sending by email.

Yes. The buttons in the top bar allow you to export the complete configuration as a JSON file, import a previously saved configuration and share a direct link that contains all the configuration encoded in the URL. That way you can prepare the exercise in advance, save it on your computer and open it identically on another occasion or device. You can also share the link directly with other teachers so they can use or adapt your exercise.
