Text Summarizer

How do I summarize a long article online for free?

Paste your article into AnyTool Text Summarizer. It ranks the sentences already in your text — by TextRank graph centrality or word-frequency scoring — and keeps the most important ones in their original order. You choose the length by percentage or sentence count, switch between a paragraph and bullet points, and get a one-line TL;DR plus key phrases. It is an extractive summarizer that selects existing sentences, not an AI that writes new prose, and everything runs in your browser so your text is never uploaded.

Two ranking methods: TextRank (graph centrality) and word-frequency scoring
Adjustable length by percentage or exact number of sentences
Paragraph or bullet output, a TL;DR one-liner and key-phrase list
Original sentence order preserved; selected sentences highlighted in the source
Extractive (selects existing sentences) and 100% client-side — no upload, no AI server

What is

A text summarizer condenses a long document into a short version. An extractive summarizer, like this tool, scores every sentence and keeps the highest-ranked ones verbatim in their original order, rather than writing new sentences the way an abstractive AI model would.

Frequently Asked Questions

This tool does not rewrite or paraphrase. It is an extractive summarizer: it splits your text into sentences, scores them with TextRank or word-frequency ranking, and keeps the top sentences exactly as written, in their original order. Every word in the summary appears verbatim in your source, which is what makes it instant, deterministic and fully private.

No. It is extractive — it selects and re-orders the most important existing sentences and never invents new wording.

TextRank builds a graph where sentences are nodes and edges are weighted by shared words, then runs a PageRank-style calculation so sentences connected to many other important sentences rank highest — it works well on flowing prose. Frequency scoring sums the normalised frequency of each sentence’s content words with small position and length bonuses, which is fast and robust on shorter or list-like text. You can switch between them and compare.

TextRank ranks sentences by how central they are in a similarity graph; frequency scoring favours sentences full of the most common content words.

Use the length control to choose a target as a percentage of the source sentences (for example 30%) or as an exact sentence count. The summary, reduction percentage, word counts and the highlighted source view all update immediately, so you can dial in exactly how concise you want the result.

Yes. Set it as a percentage of the original or as an exact number of sentences with the slider.

There is no server and no AI API call. Sentence splitting, scoring and key-phrase extraction all run locally in JavaScript, with long articles processed in a background Web Worker so the editor stays responsive. The page works offline after first load, so you can safely summarize confidential reports, research or contracts.

Nothing is uploaded. All ranking runs in your browser, so your text stays on your device and the tool works offline.

Detailed Explanation

Methodology

How the Text Summarizer Works

AnyTool Text Summarizer is an extractive summarizer that runs entirely in the browser. It splits the text into sentences (guarding against false breaks on abbreviations, decimals and initials), then ranks them with one of two methods. TextRank builds a graph in which sentences are nodes and edges are weighted by shared content words, then runs a damped PageRank power iteration so the most central sentences score highest. The frequency method scores each sentence by the summed, length-normalised frequency of its content words plus small position and length bonuses. The top-ranked sentences are kept verbatim and returned in their original document order.

Extractive, not abstractive — selected sentences are kept word for word
TextRank uses PageRank-style centrality over a sentence-similarity graph
Frequency mode uses normalised term frequency with position and length bonuses
Selected sentences are returned in original document order for natural flow
All processing is client-side JavaScript — no server, no AI API, no upload

How It Works

Length, Output Formats and Key Phrases

Summary length is adjustable either as a percentage of the source sentences or as an exact sentence count, with a slider and live word-count reduction. Output can be a clean paragraph or bullet points, and a one-line TL;DR surfaces the single highest-ranked sentence. The tool also extracts key phrases — frequent content words and recurring two-word phrases, with bigrams boosted — and can highlight the chosen sentences inside the original text so the selection is transparent.

Length set by percentage or by exact number of sentences
Paragraph or bullet-point output, plus a TL;DR one-liner
Key-phrase extraction from single words and recurring bigrams
Original-text highlighting shows exactly which sentences were chosen
Reports original vs summary word count and reduction percentage

Privacy & Security

Privacy and Honest Scope

Because summarization is extractive and local, the document never reaches a server and the page works offline after first load. The trade-off is honest: an extractive summarizer condenses by selecting existing sentences, so it cannot rephrase or merge ideas the way a large language model can. In return it is instant, deterministic, free of hallucination, and completely private — long articles are processed in a Web Worker so the editor stays responsive.

Summarizing text: extractive in-browser (AnyTool) vs typical AI summarizers
Capability	AnyTool	Typical AI summarizers
Method	Extractive (TextRank / frequency)	Abstractive (server LLM)
Text handling	Processed in your browser	Uploaded to a server / API
Privacy	Text never leaves device	Sent to and often logged by a server
Hallucination risk	None — sentences are verbatim	Possible — wording is generated
Length control	Percentage or exact sentences	Often preset or limited
Output options	Paragraph, bullets, TL;DR, keywords	Varies
Works offline	Yes (PWA)	No
Cost / signup	Free, no signup, no word cap	Often gated or word-capped

AnyTool is honest about scope: an extractive summarizer selects the best existing sentences rather than writing new prose, so it cannot rephrase ideas like a server-side language model — but it is instant, private and free of hallucination.
