How to Summarise an Article Quickly: The First-Sentence Method

The short answer

A fast way to summarise a well-written article is to read the first sentence of each paragraph, because that is usually where the writer puts the main point. The free Text Summarizer does exactly this: it takes the first sentence of every paragraph and joins them into a short extract. Then spend two minutes tightening that extract by hand. It does not rewrite or interpret the text, so the quality of the summary depends on how clearly the original is written.

Why the first sentence works

Many articles, reports and essays follow the same pattern: each paragraph opens with a "topic sentence" that states its point, and the rest of the paragraph supports it with detail, examples or evidence. News writing goes further and puts the most important information first.

If you read only those opening sentences in order, you get the skeleton of the argument. That is the idea behind the first-sentence method, and it is a well-known speed-reading and note-taking technique.

How the Lazyblink summariser works

Knowing exactly what the tool does helps you get good results:

It splits your text into paragraphs wherever there is a blank line.

In each paragraph, it takes the text up to the first full stop, question mark or exclamation mark.

It joins those sentences, in order, into one block.

So a 10-paragraph article gives a 10-sentence summary. It does not score sentences for importance, combine ideas or write new wording. Nothing is sent to an AI service; the extraction happens in your browser.

Step by step

Copy the article text. Keep the blank lines between paragraphs.

Paste it into the Text Summarizer. The word count appears below the box.

Click Summarize.

Read the result and copy it.

Edit the extract: delete sentences that are only introductions, merge ones that repeat, and add any key number or conclusion the extract missed.

A worked example

Input (three paragraphs):

> Remote work has changed how small teams hire. Companies can now recruit across time zones, which widens the talent pool. It also adds scheduling friction.

>

> The biggest cost is communication. Teams that write things down tend to cope better than teams that rely on calls. Shared documents replace hallway conversations.

>

> Dr. Mehta, who advises startups, recommends a weekly written update. She says it saves meetings.

Output:

"Remote work has changed how small teams hire. The biggest cost is communication. Dr."

The first two sentences are a decent skeleton. The third shows the method's main weakness: the full stop in "Dr." looks like the end of a sentence, so the extract stops after two letters.

Fixing common problems

The summary is only one sentence

The tool found only one paragraph. This usually happens when text copied from a web page or PDF loses its blank lines. Add an empty line between paragraphs and run it again. Single line breaks are not treated as paragraph breaks.

A sentence is cut off after an abbreviation

Abbreviations such as "Dr.", "Mr.", "e.g.", "approx." or "No. 5", and decimal numbers like "3.5", contain full stops that end the extracted sentence early. Either fix those lines in the output by hand, or temporarily remove the dot in the input (for example, write "Dr" instead of "Dr.").

The summary misses the conclusion

If an author builds up to their point at the end of a paragraph, the first sentence will not capture it. Opinion pieces, stories and persuasive essays often work this way. For those, read the last sentence of each paragraph too, and add it where it matters.

The summary includes greetings or headings

Headings, captions and lines like "Read more" count as paragraphs if they are separated by blank lines. Delete them from the input, or remove them from the output.

When to use this method and when not to

Good fit:

• News articles, reports, documentation and textbooks with clear topic sentences.
• Getting a quick outline before reading the full text.
• Making revision notes from a chapter.

Poor fit:

• Fiction, poetry and dialogue.
• Legal or medical text, where a missed qualification changes the meaning. Read the full text.
• Very short text of one or two paragraphs; just read it.

Writing a better summary by hand

The extract is a starting point. To turn it into a real summary:

State the main point first, in your own words, in one sentence.

Keep only the supporting points a reader needs to understand it.

Keep key numbers and names exactly as in the source.

Cut examples and repetition. A summary is usually around a tenth to a quarter of the original length, but the right length depends on what it is for.

Check it against the original so you have not changed the meaning.

Use the Word Counter to check your summary length. If your summary is for school or work, credit the source and avoid copying long passages word for word.

Turning the extract into notes

For study or meeting notes, bullet points are often more useful than a paragraph:

Put each extracted sentence on its own line.

Shorten each to its key phrase: "The biggest cost is communication" becomes "Main cost: communication".

Under each point, add one detail from the original paragraph if it matters, such as a number or name.

Add a final line with the article's conclusion in your own words.
