How TextRank summarization works
Sentence segmentation
Your text is split into sentences using a parser that understands abbreviations, decimals, and punctuation edge cases.
Tokenization & stopword removal
Each sentence is reduced to its key content words. Stopwords like 'the' and 'and' are ignored for scoring.
Similarity graph
Every pair of sentences gets a similarity score based on shared content words. This builds a weighted graph.
PageRank scoring
We run PageRank over the graph. Sentences that share content with many other sentences score higher — they represent central ideas.
Top-N selection
The highest-scoring sentences are picked. They are reordered into their original document position for a natural flow.
Key takeaways
The top five sentences by score (truncated at 120 characters) become your bullet-style key takeaways.

Frequently asked questions
Is my text really private?
Yes. Everything runs in your browser using JavaScript. We never upload, log, or see your text. There is no server processing — you can disconnect from the internet after the page loads and it will still work.
Is this better than ChatGPT or Claude for summarization?
For long, factual text, TextRank is often just as useful and dramatically faster (milliseconds instead of seconds). For creative synthesis or cross-document reasoning, a large language model is better. We think TextRank is the right tool for most day-to-day summarization needs.
Does it work with languages other than English?
Yes — any Latin-script language (Spanish, French, Portuguese, German, Italian, Dutch, and more) works. We auto-detect English to apply stopword filtering for optimal results. Non-English text still summarizes, just without the stopword optimization.
How long can the input text be?
No hard limit. We've tested with 50,000-word inputs and it completes in under a second. The algorithm is O(n²) on sentence count, so truly enormous inputs (hundreds of thousands of words) may take a few seconds.
Why TextRank instead of AI?
TextRank is an extractive algorithm — it picks actual sentences from your source text, so it never hallucinates or invents facts. It's the right choice when accuracy and fidelity to the original matter most.
Can I use the summaries commercially?
Yes. The summaries are derived from your own input text. We claim no ownership over anything processed by the app.

How to summarize long text quickly
Reading long articles, research papers, or meeting transcripts end-to-end is often not feasible. A good summarizer extracts the sentences that carry the most information and presents them in a compact, readable form. This free text summarizer uses the TextRank algorithm — a variant of Google's PageRank applied to sentences — to identify which parts of your text are most central to the overall meaning.
What makes a good summary?
A useful summary preserves the key facts and ideas from the original while cutting redundant framing, transitional language, and peripheral detail. It should be short enough to read in a fraction of the time but substantive enough that the reader can make decisions without opening the source.
When extractive summarization is the right choice
Extractive summarization pulls sentences directly from your input. It never rewrites, paraphrases, or invents new content. This matters for academic papers, legal documents, and news — anywhere a verbatim quote is useful and hallucination would be costly. Use our TextRank vs AI summarization comparison to understand the tradeoffs.
How to get the best results
- Paste clean text — strip out navigation chrome, ads, and footers.
- Aim for at least 100 words of input for meaningful scoring.
- For dense, information-rich text (abstracts, legal briefs) try 30–50% length. For narrative content (essays, blog posts) 10–20% works better.
- If a summary misses a point you care about, increase the sentence count — that point may have a lower-but-still-valid score.
Why use a browser-based summarizer?
Hosted AI summarizers send every word of your document to someone else's servers. For sensitive content — legal drafts, confidential meeting notes, unpublished manuscripts — that's a non-starter. Our summarizer runs entirely in your browser using JavaScript. The text you paste stays on your device. There are no accounts, no tracking of inputs, and no server logs.
