What is a Text Summarizer?

Text summarizer is an AI-based online software that shortens/condenses long paragraphs to keep the main points and remove the less important details. According to Cambridge Dictionary, the definition of summarization is,

The act of expressing the most important facts or ideas about something or someone in a short and clear form, or a text in which these facts or ideas are expressed.


With so much to learn and so little time, we are always looking for shortcut ways to do things. A summary or nutshell of content gives people the main details within a short time. Everything can have a summary – movies, books, strategies, you name it.

Two ways of automated summarization

Based on the output type of summarization, there are mainly two ways to approach summarization –

  • Extraction method
  • Abstraction method

In the Extractive text summarization method, no new text is added to the output. Instead, the machine scans the input text and extracts only the important sentences, and removes the other less important sentences.

The extractive method entails extracting the most essential words and sentences from the content. The summary is then created by combining all of the essential lines. In this scenario, every line and word of the summary is taken from the original document that is being summarized.

Abstractive text summarization method is one kind of deep learning summarization. Unlike the extractive method, the abstractive summarization method reconstructs the given input text and keeps the important sentences in the output. In essence, this type of summarization works like we summarize in real life. It also means that the abstractive text summarization is pretty tougher to execute than the extractive method.

Paraphrasing vs summarizing

Paraphrasing and summarizing are closely related, and yet, these are not the same thing.

According to the Merriam-Webster dictionary, the definition of paraphrasing is stated as –

A restatement of a text, passage, or work giving the meaning in another form.

So, paraphrasing is taking some text and restating that text in different words while keeping the original meaning. Paraphrasing doesn’t necessarily mean shortening or lengthening the original text.

Summarizing, on the other hand, is based on shortening the original text into the basic elements of the content. So, shortening the length of the text is a must in summarization. And the summary can be either extractive or abstractive. While summarizing, one doesn’t have to necessarily change the wordings and the phrases of the content; instead, they have to keep an eye on keeping the only important parts and removing the rest of the text.

Paraphrasing is important when you want to present someone’s text in your own way. And you can either paraphrase manually or for less trouble, use a paraphrasing tool. But when you also want to reduce the text to its essence, you have to summarize, which you can do manually, or get a summarizer tool to do it for you.

How to avoid plagiarism by summarizing text

As per Oxford Languages, Plagiarism isthe practice of taking someone else's work or ideas and passing them off as one's own.

Plagiarism can be daunting for anyone. It can make you lose your credibility and also ruin the original author’s efforts as well.

Summarizing, however, lets you easily take the original idea from someone and present it concisely in your own words. With summarization, you don’t have to worry aboutplagiarizing since you can express the author’s main idea and still call the text your own by reducing it to its essence.

How this tool works

By using different AI components such as NLP and Machine Learning, this tool scans the input text and decides upon the most important sentences. Then it removes the less important parts from the text and only keeps the chosen important sentences. And then it arranges the selected sentences to create an output.

You can use this summarizing tool for any type of text; be it for school, business, books, or even text messages, you can save a lot of reading time with this summarizer.
