How the summary is made
This is an extractive summarizer. It does not write new sentences. It scores every sentence by how much it shares key terms with the rest of the text, then picks the highest-scoring ones and shows them in their original order. This keeps the wording accurate, because every sentence in the summary comes straight from your text.
Choose a length
- By percentage: Very short (about 15% of the sentences), Short (30%) or Medium (50%).
- By number: exactly 1, 3 or 5 sentences.
- Show as bullet points: puts each summary sentence on its own line, which is handy for notes and slides.
A line under the result tells you how many sentences and words were kept, for example 4 of 12 sentences, and lists the key topics found in your text. The text needs at least three sentences, and very long input is limited to the first 600 sentences.
Where it works best
- Articles, reports, essays and meeting notes with clear, full sentences.
- Getting the gist of a long document before you read it in full.
- Making study notes from a chapter or a lecture transcript.
- Drafting an executive summary that you then edit by hand.
Limits to know about
- It cannot rephrase, combine or explain ideas, so the summary can feel choppy.
- Lists, tables and text without full stops are not summarized well.
- Check the summary against the original for important details such as numbers and names.
- To reword the result, run it through the Paraphrasing Tool, and to see how long it is use the Word Counter.
Frequently asked questions
How does this summarizer work?
It is an extractive summarizer: it scores each sentence by how many important (frequent, non-trivial) words it contains and keeps the highest-scoring ones. It does not write new sentences.
Is it accurate?
It works best on well-structured, factual text such as articles and reports. Always read the summary to make sure no essential point is missing.
Is it AI?
No. It uses a statistical ranking of sentences that runs in your browser. Nothing is sent to a server, so private documents stay on your device.
Why is my summary only one sentence?
Check the length setting. The “1 sentence” option returns the single highest-ranked sentence, and percentage options always return at least one sentence.
