Check the highlights
The original text is shown with the selected sentences marked, so you can see what was kept and what was dropped.
- This is extractive, not abstractive: it picks whole sentences out of your text and never rewrites them.
- Well-structured writing with clear topic sentences summarises far better than dialogue or lists.
- For a paper, the abstract and conclusion usually contain the sentences that score highest.
- Try two or three lengths - the shortest one often states the core idea most clearly.
- Extractive summarisation by sentence scoring
- Scores from stop-word-filtered word frequency, plus an opening-sentence bonus
- Short / medium / long or an exact sentence count
- Key-point extraction and highlighted source text
- Runs entirely in your browser - nothing is sent anywhere
- Skim a long report before a meeting.

Stop words are removed, the remaining words are counted, and those counts are normalised against the most frequent word. Each sentence scores the average frequency of its words, with a small bonus for the first two sentences. The top-scoring sentences are returned in document order.
No. No language model is involved and nothing is sent to a server. The summary is made only of sentences copied verbatim out of the text you pasted, which is why it can never invent a fact that was not there.
It works on any language that separates words with spaces, though the stop-word list is English, so a German or Spanish summary will be rougher than an English one.
