Why use Text Summarizer?

This summarizer uses an extractive approach: it scores every sentence in your text based on how many significant (non-filler) words it shares with the rest of the passage, then keeps the highest-scoring sentences in their original order. Because it selects real sentences instead of generating new text, the summary never introduces information that wasn't in the original. Use the slider to control how aggressive the summary should be — fewer sentences gives a tighter summary, while more sentences preserves more supporting detail.

Frequently asked questions

How does the summarizer choose sentences?

It scores each sentence by how many frequently-used, meaningful words it contains, then keeps the highest-scoring sentences in their original order.

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?

The tool works best on text with at least a few sentences. Very short text may not have enough sentences to summarize meaningfully.

Is my text uploaded anywhere?

No. Summarization runs entirely in your browser using JavaScript — nothing is sent to a server.

Can I summarize non-English text?

The tool works on any Latin-alphabet text, but the word-frequency scoring is tuned for English stopwords, so results are most accurate in English.
