Fill-in-the-Blank Study Tool

Paste a passage from your notes or textbook, hide the key words, and fill in the blanks to learn it. Use it to make a cloze test for yourself before an exam.

How to use

1. On the "Make blanks" tab, paste the passage into "Text to learn".
2. Under "Words to hide", choose "Pick by hand", "Random share", "Every nth word", "Numbers only" or "Words in [[brackets]]". You can also tap words in the text below to hide or show them.
3. On the "Study" tab, use "Tap to reveal" to open answers one by one, or "Type and check" to type the answers and press "Check".
4. Press "Retry the wrong ones" to try the missed blanks again, or "Print worksheet" to practise on paper.

How it works

• Wrap key words in [[double brackets]] to hide exactly those words. The text is split into words with the browser's language-aware word segmentation.
• Checking ignores capital letters, spaces and punctuation at the start or end of an answer. As a hint, the blank can show the "First letter" or the "Length".
• The printed worksheet numbers each blank and lists the answers separately below the text.
• Several materials are saved in this browser on this device. On the "Backup" tab you can export and import them as a JSON file.

Questions and answers

How do I make a fill-in-the-blank test automatically?

"Random share" hides a chosen share of the words at random (30% by default), and "Every nth word" hides words at a fixed interval, such as every 5th word. "Reshuffle" hides different words.

Can I hide only dates and numbers?

Yes. "Numbers only" hides every word that contains a digit, such as 1446 or 3.14. This helps when you learn dates or quantities.

Can I hide whole phrases instead of single words?

Yes. Text inside double brackets, such as [[carbon dioxide]], becomes one blank. Choose "Words in [[brackets]]" to hide only those.

Can I print a worksheet with an answer key?

Press "Print worksheet". The sheet has a name and date line, numbered blanks and the answer key.
