Why use Text Summarizer?

This summarizer uses an extractive approach: it splits your text into sentences, counts how often each meaningful word (three letters or longer, excluding common filler words) appears across the whole passage, then scores each sentence by the average frequency of the words it contains. The sentences with the highest scores are kept, restored to their original order, and joined into the summary. Because it selects real sentences instead of generating new text, the summary never introduces information, opinions, or phrasing that wasn't in the original. The slider controls how many sentences make it into the final summary, up to the total number of sentences detected in your text. Fewer sentences gives a tighter, headline-style summary, while more sentences preserves additional supporting detail. A word count comparison below the result shows exactly how much shorter the summary is, so you can judge the reduction at a glance before copying it.

Frequently asked questions

How does the summarizer choose sentences?

It counts how often each significant word appears across your text, scores every sentence by the average frequency of its words, then keeps the highest-scoring sentences.

Does this generate new sentences?

No. This is an extractive summarizer. It selects existing sentences from your text rather than writing new ones, so the summary is always accurate to the source.

What is the minimum text length?

If your text has fewer sentences than the slider is set to, the tool simply returns every sentence. It works best on text with at least a handful of sentences.

Is my text uploaded anywhere?

No. The word-frequency scoring that picks which sentences to keep runs as JavaScript in your browser, so drafts or client documents are never transmitted to a server.

Can I summarize non-English text?

The tool works on any Latin-alphabet text, but short filler words are filtered using an English stopword list, so scoring and results are most accurate in English.
