What is a text summarizer, and why use one?
A text summarizer shortens a long piece of writing to the sentences that matter most. It saves time on articles, reports, meeting notes, essays and emails you need to understand quickly, and gives you a starting point for notes or an abstract. This tool summarizes text online without AI, so the result is predictable: every sentence in the summary comes word for word from your original.
How Rule-Based Summarization Works
Instead of guessing, a rule-based summarizer follows a fixed method. Because it is just counting and ranking, it runs instantly in your browser and gives the same result every time for the same text.
1. Split into sentences
The text is divided into sentences. Abbreviations such as Dr. and e.g., initials and decimal numbers are handled so they don't cut a sentence in half.
2. Score the keywords
Common words like the, and and of are ignored. The remaining words are counted, and words that appear often are treated as the main topics.
3. Rank and pick sentences
Each sentence is scored by the keywords it contains, with a small boost for opening sentences. The best ones are kept until the summary reaches your chosen length.
4. Put them back in order
Chosen sentences are shown in their original order, so the summary reads the way the text does. Near-duplicates are skipped.
Choose a Summary Length
Short (10%)
About a tenth of the original. Good for a quick idea of what a long article or report covers.
Medium (20%)
About a fifth of the original. A balanced summary that keeps the main points and a little supporting detail.
Long (30%)
About a third of the original. Keeps more context, useful for longer documents or when you don't want to miss details.
Custom (5–90%)
Type any percentage. The summary stops at the sentence that gets closest, so the final length is shown next to your original word count.
Your Text Stays on Your Device
Everything on this page runs in your browser. Your text is never uploaded, logged or stored, which makes it safe for drafts, contracts, research notes and anything else you'd rather keep to yourself. It's also fast, because there's no waiting on a server, and it keeps working even if your connection drops after the page has loaded.
Supported Text Lengths and Formats
Paste or type plain text, or load a .txt file of up to 2 MB. The summarizer handles up to 300,000 characters at once, roughly 50,000 words, and needs at least about 30 words and two sentences to work with. It works best on prose such as articles, essays, reports and emails. Line breaks and paragraphs are kept, and lists or headings without full stops are treated as separate lines rather than sentences.
Works on Mobile and Desktop
The summarizer works in any modern browser on phones, tablets and computers, with nothing to install. On a large screen your text and summary sit side by side. On a phone they stack, and every button is sized for touch.
