When writing a paper, do you struggle with choosing which references to use? When analyzing market trends and competitors, are you driven to despair by dozens or even hundreds of pages of industry research reports?
In any scenario, AI summarizers have become a powerful tool to improve efficiency.
In this guide, we will explore the best AI tools for summarizing long articles and discuss in depth how to write a perfect summary.
What Is a Summary?
It is a simplified version of the original text, which summarizes the main idea of the original text and eliminates unnecessary details. The core of writing a summary is to distill a large number of texts into their basic elements.
How long should the summary be?
Generally speaking, the length of the summary should be 10% to 25% of the length of the original text. However, the length of the summary will vary according to its purpose:
- Academic summary: in more detail
- Business summary: concise and easy to operate.
- Blog/article summary: Focus on key points.
If you want to know how long the summary should be, the answer depends on clarity, not just the number of words.
How many paragraphs should the summary contain?
Structure usually depends on the original text:
- Essay: Usually, one paragraph is enough.
- Long article or report: 2-4 paragraphs or structured chapters.
- Research summary: multiple chapters (objectives, methods, results, and conclusions)
Therefore, the number of paragraphs in the summary is not fixed, but will change with the complexity of the content.
Why is the summary title important?
Don't ignore the summary title. A concise and descriptive title can ensure that the information is easy to search. It should be:
- Clear
- Specific
- Engaging
For example: Instead of “Summary of Article”, use “Key Insights from AI Trends in 2026”.
What Is the Main Purpose of the Summary?
- Save reading time
- Improve comprehension of articles requiring summarization.
- Highlight key points in long articles.
- Help you decide whether to read the entire article.
In short, a summary makes information easier to obtain and apply.
