Text Summarizer
Extractive summary: the most representative sentences, nothing invented or uploaded.
About this tool
Paste a long text, set how much to keep, choose paragraph or bullets: the sentences that carry the document's key terms are selected and shown in their original order, with the reduction and key terms reported. Nothing is uploaded.
Extractive versus generative, honestly
There are two kinds of summary. A generative summary (what a chat AI writes) is fluent, can compress ideas, and can also state things the source never said β the failure mode you can't detect without reading the original. An extractive summary picks sentences from the text itself: less elegant, but every sentence is a real sentence from the document, so nothing is invented and the source is one search away. This tool is the second kind, in the tradition of the research systems that predate language models: it counts the document's content words (stopwords removed), scores each sentence by how many top terms it carries, normalised for length, with a bonus for opening sentences because writers front-load their point, and keeps the highest-scoring ones in order. It runs in your browser, instantly, on text you might not want to paste into a cloud service. Where it works well: news, reports, papers, minutes, transcripts, long emails β one topic, informative prose. Where it doesn't: stories and dialogue, where the important sentence is rarely the keyword-dense one. Pair it with the word frequency counter for the raw term counts and the word counter for reading time.
Frequently asked questions
Is this AI?
No β it's an extractive algorithm: sentences are scored by the document's own key terms and the best are kept verbatim. Nothing is rewritten, so nothing can be made up.
How much should I keep?
25% is a good default for articles; 10β15% for a long report's gist; 40% or more when every point matters. The counter shows the reduction.
Why does the summary read a bit disjointed?
Because the sentences are the original ones, in order, with the ones between them removed. That's the trade for guaranteed faithfulness; bullet format often reads better.
Is my text uploaded?
No β scoring runs in your browser. Confidential documents stay on your device.
