Frequently Asked Questions
How does the text summarizer work?
This tool uses extractive summarization. It scores each sentence based on the frequency of meaningful words and selects the top-scoring sentences to form the summary — preserving the original wording.
Is my text sent to a server or AI model?
No. The summarization runs entirely in your browser using JavaScript. Your text is never uploaded to any server. This makes it completely private.
What is the difference between extractive and abstractive summarization?
Extractive summarization picks existing sentences from the text. Abstractive summarization (used by AI models like GPT) generates new sentences that paraphrase the content. Extractive summaries always use the author's exact words.
What types of text work best?
The summarizer works best with structured texts: news articles, essays, reports, and documentation. It works less well with dialogue, bullet-point lists, and conversational text.
Shorten long text to its key points
A text summarizer condenses a long passage into a shorter version that keeps the main points. Paste an article, report or set of notes and get a tighter summary you can read in a fraction of the time.
It is a fast way to grasp the gist of something before deciding whether to read it in full.
When summarising saves time
- Skimming articles, reports and research.
