Text summarizer
Paste an article, report or set of notes and this tool returns a short summary made entirely of sentences pulled from your original text. It is an extractive summarizer: instead of generating new sentences, it scores every sentence in the input and keeps only the ones that matter most, printed back in the order they originally appeared.
Each sentence is scored on how often its important words repeat across the whole text, where it sits in the passage, and how long it is — very short fragments and overly long run-ons are scored down. Choose how much to keep with either a fixed number of sentences or a percentage of the original length, and pick whether the summary reads as a paragraph or as a bulleted list. Turning on "ignore common words when scoring" strips filler words like "the" and "and" out of the frequency count so the ranking reflects actual content, and "show each sentence's score" prints the numeric score next to every kept sentence so you can see why it was chosen.
Prefer to see the selection in context rather than pulled out on its own? Enable "highlight selected sentences in the original text" and the tool returns your full text unchanged, with the chosen sentences wrapped in double asterisks instead of extracted. The tool handles Windows (CRLF) and Unix (LF) line endings the same way, copes with very long documents, and the live tally below the output reports total sentences, how many were kept, and the exact character count.
Everything runs locally in your browser — nothing you paste is uploaded or sent to any server, which makes it safe to use on private drafts, internal reports or unpublished manuscripts. Copy the summary, download it as a .txt file, or send it straight to another tool's input to keep working on it.
FAQ
How does the summarizer decide which sentences to keep?
Each sentence gets a score based on how frequently its keywords appear across the whole text, its position in the passage, and its length. The highest-scoring sentences are kept, and they are printed back in their original order rather than by score.
What's the difference between choosing a sentence count and a percentage?
A fixed count always keeps exactly that many sentences regardless of document length. A percentage scales with the input, so a long document keeps proportionally more sentences than a short one.
Can I see the selection inside the full original text instead of a shortened summary?
Yes. Turn on "highlight selected sentences in the original text" and the tool prints your whole text back with the chosen sentences wrapped in ** markers, instead of extracting them into a separate summary.
Does ignoring common words change the result?
Yes. With it on, filler words like "the", "and" and "is" are excluded when scoring, so sentences are ranked by their actual content words. Turn it off to score every word, including common ones.
Is my text uploaded anywhere?
No. Summarization runs entirely in your browser using plain JavaScript — your text is never sent to a server.
