Pull out the most important sentences from any long text
Here’s the idea: you’ve got a 20-sentence article and you need the gist in 3 sentences. This tool scores every sentence based on word frequency, position (first and last sentences carry extra weight), and length (medium-length sentences win over very short or very long ones). Then it picks the top scorers and presents them in their original order.
This is extractive summarization: it pulls real sentences from your text, it doesn’t generate new ones. No AI model rewriting your words. No API calls. Just statistical scoring running in your browser. The same input always produces the same summary.
What it does
- Selects the most information-dense sentences from your text
- You pick how many sentences you want in the summary (default: 3)
- Shows the reduction percentage, “you went from 500 words to 75, an 85% reduction”
- Selected sentences keep their original order for natural reading
- Deterministic: same input, same output, every time
- Runs entirely in your browser
How to use it
Paste your text. Pick the number of sentences. Click Summarize. Copy the result.
The tool works best on factual, information-heavy content, news articles, reports, documentation. Give it at least 5-10 sentences to work with, otherwise there’s not enough material for meaningful extraction. Narrative or creative writing produces less reliable summaries because important information isn’t concentrated in specific sentences the way it is in factual prose.
Real scenarios
Research: you’ve got a stack of papers to review and you need to decide which ones to read in full. Paste the abstract or introduction, get the key sentences, make your call. Honestly, this has saved me hours during literature reviews.
Blog excerpt generation: need a teaser for your article listing page or newsletter? Summarize to 2-3 sentences and you’ve got a ready-made preview.
Long email triage: someone sent a 12-paragraph email. Is it important? Paste it in, get the top 3 sentences, decide if it’s worth reading the rest.
Meeting minutes: condense lengthy meeting notes into the key decisions and action items. Set a higher sentence count (5-7) for more coverage.
News digestion: skim long articles faster by extracting the core information.
After summarizing, you might want to check the summary length with the Word Counter or estimate reading time with the Reading Time Estimator. The Sentence Counter can analyze the structure of both original and summary.
FAQ
How does the scoring work?
Three factors. Word frequency: sentences with commonly used words in the text score higher (they’re covering key topics). Position: first and last sentences get a boost (they often contain thesis statements and conclusions). Length: extremely short or long sentences get penalized.
Is this AI?
No. It’s statistical analysis, word frequency and heuristic scoring. No neural network, no language model. The advantage? It’s transparent, fast, and deterministic.
How many sentences should I pick?
For a quick overview: 2-3. For something more thorough: 5-7. A good rule of thumb is 20-30% of the original sentence count.
Non-English text?
Works with any space-separated language, but the heuristics are tuned for English. Results in other languages may vary.
Is my text private?
Yes. All processing happens in your browser. Nothing is transmitted. Safe for confidential documents, unpublished research, and private content.
