Paste long text and get the most important sentences extracted instantly — a fast, private, browser-based summarizer.
It uses extractive summarization, scoring each sentence by word frequency and selecting the highest-scoring ones, rather than generating new sentences.
No, this uses a statistical, rule-based approach that runs entirely in your browser, rather than an AI language model generating a new abstractive summary.
This works best on text with at least several sentences — very short text (1-2 sentences) won't benefit much from summarization.
Yes, selected sentences are presented in their original order from the source text, not reordered by importance.
This tool creates a summary of long text by identifying and extracting the most important sentences, using a word-frequency scoring approach that runs entirely in your browser — no external AI service required.
There are two fundamentally different approaches to automatic text summarization. Extractive summarization — what this tool does — selects existing sentences directly from the source text based on how important or representative they seem, and presents them as the summary. Abstractive summarization, by contrast, generates entirely new sentences that paraphrase and condense the original meaning, similar to how a human might summarize in their own words — this typically requires a large language model and is not what this browser-based tool performs. Extractive summarization is faster, fully private (no data leaves your browser), and doesn't risk introducing factual errors through paraphrasing, though it can't rephrase or truly condense ideas the way abstractive summarization can.
This tool first breaks your text into individual sentences, then builds a word frequency count across the entire text (ignoring common "stop words" like "the," "a," and "and," which carry little meaning). Each sentence is then scored based on how many frequently-occurring, meaningful words it contains — sentences packed with the text's most repeated key terms score higher, on the theory that these sentences are more likely to represent the core content. The highest-scoring sentences (however many you've requested) are selected and presented back in their original order.
It works less well on very short text, text without clear sentence structure, or content where every sentence is equally important (like a list of distinct facts rather than a flowing narrative).
All summarization happens directly in your browser using JavaScript — your text is never sent to a server or any external AI service.
