About the Text Summarizer
The Text Summarizer produces an extractive summary: it picks the most important sentences out of your text and joins them in their original order. It never writes, paraphrases or invents a new sentence, so every word came verbatim from what you pasted. Under the hood it counts how often each meaningful word appears (ignoring roughly forty common stopwords like “the” and “and”), scores each sentence by the combined frequency of its words — adjusted for length so a long sentence does not automatically win — and keeps the highest-scoring ones up to the number you choose.
That makes it a fast way to skim a dense article, a report or a page of meeting notes. Because the whole thing runs in your browser, nothing you paste is uploaded or stored, which is handy for confidential drafts.
Two honest limits. The summary can only be as good as the original writing; on rambling or list-like text the “top” sentences may not read smoothly side by side. And the sentence splitter is a simple regex that treats any full stop as a break, so “Dr.” or “3.14” can be mis-split, and it is tuned for English. For a companion view of the same text, try the readability checker or the keyword density checker.
Frequently asked questions
Does it use AI to write the summary?
No. It is extractive: it selects and reorders sentences that already exist in your text, and never generates new wording. If you need a rewritten or paraphrased version, this is not that kind of tool.
How does it decide which sentences matter?
It counts how often each significant word appears across your text, then scores each sentence by the summed frequency of its words, adjusted for the sentence length. The top-scoring sentences, restored to their original order, become the summary.
Why did my whole text come back unchanged?
If your text has the same number of sentences you asked to keep, or fewer, there is nothing to trim, so it returns everything with a note. Paste more text or lower the number of sentences to keep.
Is my text sent to a server?
No. The summarizer runs entirely in your browser, so nothing you paste leaves your device or is stored anywhere.
Why does the summary sometimes read awkwardly?
Because it joins existing sentences rather than writing connective wording, sentences that were far apart in the original can end up next to each other. It also relies on a simple sentence splitter that can miscount around abbreviations like “Dr.” or decimals like 3.14.
