About this tool

This summarizer uses extractive scoring — the same family of algorithms behind many news-digest tools: it weights words by frequency, scores every sentence by the important words it contains, keeps original wording (no invented facts), and returns the top sentences in their original order. Because it runs entirely in your browser, you can summarize confidential documents safely — unlike cloud summarizers that receive your full text. Your file never leaves this page — everything runs in your browser, there is no upload endpoint on this site, and the file is dropped from memory when you close the tab.

FAQ

Is my text uploaded?

No — Your file never leaves this page — everything runs in your browser, there is no upload endpoint on this site, and the file is dropped from memory when you close the tab.

How does it pick sentences?

By word-frequency scoring plus a bonus for early position — the standard extractive method.

Does it invent anything?

No — it only selects original sentences, so facts are never paraphrased wrongly.

Best length of input?

150+ words; very short texts don't need summarizing.

Works in other languages?

Yes for any language with spaces between words; the stopword list is English-based.

Can I summarize a URL?
