What is a sentence duplicator?
learn more about this toolWith this online tool, you can make multiple copies of all or some sentences of the given text. By default, the "Duplicate All Sentences" option is enabled and in this mode, the program automatically finds each sentence in the text and repeats it as many times as necessary. The number of sentence copies can be specified in the options using a single number, such as 2, 3, or 4. If you don't need to duplicate all sentences, then you can switch to the "Duplicate Certain Sentences" mode. In this mode, the program creates copies of sentences that match the patterns you have specified. For example, by specifying the pattern "red cat" in the text option, the utility will duplicate all sentences containing this specific substring. For instance, if the input text is "The red cat is purring. The black dog is wagging its tail. The sun shines on the red cat.", then the utility will create copies for the first and third sentences. If you additionally want to match all sentences containing the substring "black dog", then enter this pattern in the same option, but on a new line. Each of these patterns must match the text in a sentence exactly. However, if you're not sure that the words "red" and "cat" will be next to each other in the text, you can use the "+" symbol to extract sentences where these words are separated by some other words. For example, if the input text is "I have a cat of red color", then the pattern "red cat" won't match this sentence and it won't be duplicated, but the pattern "red + cat" will. Note that there's a space before and after the "+" symbol. This way of matching can also be extended to three, four, or more words. For example, you can write "red + cat + sleep + eat" and then all four of these words must be present in a sentence. To include uppercase words in pattern matches (such as "Red cat"), turn off the "Case Sensitive Patterns" option. Additionally, you can activate the "One Sentence Per Line" option so that all sentences of the text are displayed vertically in a column for easier overview. Textabulous!

In this example, we create two pairs of all the sentences in a poem. To do this, you turn on the "Duplicate All Sentences" mode and specify the number of copies to be 2.

Repeat Specific Sentences
In this example, we create three repetitions only of specific sentences of the text, the ones that contain the plural word "Dogs". To do this, we switch to the "Duplicate Certain Sentences" mode and enter the word "Dogs" in the sentence patterns option.
Dogs are loyal. They make great companions. They come in all shapes and sizes. Dogs are man's best friend.

Several Search Patterns
This example only duplicates the sentences that contain two different search patterns. The first and fourth sentences are duplicated because the "ocean" pattern is specified in the options, and the third sentence is duplicated because the "universe" pattern is specified in the same option (on a new line). Each of these sentences is repeated twice in the output.
The ocean is huge. This is a mysterious place. It's like another universe. The ocean is full of life. This is a source of inspiration.

Match Two Separate Words in Sentence
In this example, we use the extended match pattern format with the "+" sign in it to match a sentence with two separate words. We specify the pattern "sing + dance" to duplicate all sentences that contain the words "sing" and "dance" (even if they are not immediately next to each other, such as "sing and dance"). We also turn off the case-sensitive option to make sure the sentences with these words are duplicated even if the words are at the beginning of the sentence or are written in uppercase.
Music is my passion. I love to sing and dance. It makes me feel alive. Singing calms my soul, and dance invigorates my body. There's nothing better than a good beat.

Copy a Sentence With a Word in the Middle
In this example, we make copies only of those sentences in the text that contains the word "cat" that's in the middle of a sentence. To make this strict matching parameter work, we add space characters to the left and right of the word "cat" making it " cat ". This way, the word "cat" can't be at the very beginning or end of the sentence (as sentences don't start with a space and don't end with a space). We repeat the matching sentences 4 times and output one sentence per line to make it easier to see which sentences were duplicated and which weren't.
I don't have a cat.
The neighbor's cat sleeps on my porch.
Wow, what a beautiful Siamese cat!
What's your name, cat?
I don't have a cat.
The neighbor's cat sleeps on my porch.

Match a Plus Sign Inside of a Sentence
As you might have seen in the previous examples, the plus sign "+" has a special meaning as it allows matching multiple words in a sentence. However, sometimes a sentence can contain the plus sign itself. In this example, we demonstrate how to duplicate sentences that use the "+" sign. To create copies of such sentences, we escape the "+" sign by making it a double plus sign "++". To match the exact substring "red + orange" in a sentence, we write "red ++ orange" and now the "+" no longer has a special meaning. If we had simply written "red + orange", then the words "red" and "orange" would have been matched separately but now the entire pattern "red + orange" must match as the double sign "++" is not a special match operator.
red + blue is purple.
red + orange is vermilion.
red + yellow is orange.
blue + green is turquoise.
yellow + green is lime.
red + green is brown.
