What is a text summarizer?
A text summarizer takes a long piece of writing and gives you the short version. You paste a news article, a long email or ten pages of notes, and you get the few sentences that carry the main message.
This one makes an extractive summary. That means it does not write new sentences. It picks the most useful sentences from your text and shows them in their original order. What you read in the summary is exactly what the author wrote, just less of it.
How does this tool work?
- You paste text or upload a .txt, .md or .html file.
- The tool cleans it up and splits it into sentences. Cookie notices, menus and repeated lines are dropped.
- It counts which words appear most often, leaving out small words like "the", "and" or "und".
- Every sentence gets a score. Important words, a place near the start, a link to the headline, numbers and words like "important" or "in short" all raise it. Very short or very long sentences lose points.
- The highest-scoring sentences are chosen. If two say almost the same thing, only one is kept.
- The chosen sentences are put back in their original order to form the summary.
- Keywords, key points and numbers such as prices, percentages and dates are pulled out and shown below.
All of this happens on your phone or computer. That is why it is fast and why your text stays private.
Short, medium or detailed?
| Length | About how much is kept | Good for |
|---|---|---|
| Short | 10–20% of the sentences | News, emails, quick articles |
| Medium | 20–30% | Blog posts, business documents, learning material |
| Detailed | 30–40% | Study notes, long reports, important documents |
These are guide values, not hard rules. A short text always keeps at least two or three sentences, and a very long text is capped so the summary stays readable.
The five summary styles
| Style | What you get |
|---|---|
| General | Summary, key points, keywords and important facts. |
| Business | Main problem, main idea, opportunity, important facts and action points. |
| Study | Topic, main concepts, key points, important terms and a quick revision list. |
| Meeting | Main discussion, decisions, tasks, dates, and the people and organisations named. |
| Business learning | The main lesson, key ideas, important actions, important numbers and words to remember. |
Each style looks for signal words such as "decided", "deadline", "problem" or "should" (and their German versions). If the text simply does not contain a decision or a task, the tool says so instead of making one up.
How to read your results
- Summary is the heart of it. Read this first.
- Key points carry small labels. "Main idea" is the highest-scoring sentence, "Fact" contains a number, "Action" tells someone to do something, and "Conclusion" is where the author sums up.
- Important keywords are the words and two-word phrases the text repeats most. They show you what the text is really about.
- Important facts show each number, amount, percentage or date with a few words around it, so you know what it refers to.
- Reading time compares the full text with the summary at about 225 words per minute.
- Show which sentences were picked displays your whole text with the chosen sentences highlighted. It is the fastest way to see what was left out.
What this tool cannot do
It does not understand meaning the way a person or an AI model does. It cannot rewrite a sentence in simpler words, join two ideas, spot sarcasm or notice that a small footnote changes everything.
It works best on clear, well-structured writing: articles, reports, notes and minutes. Chat logs, poems, tables and lists of bullet points give weaker results. A summary of a contract, a medical letter or a bank offer is a starting point, never the final word.
Who can use this tool?
- Students
- Teachers
- Employees
- Business owners
- Entrepreneurs
- Researchers
- Content creators
- Job seekers
- Bloggers
- Direct sellers
- People learning languages
A job seeker can check the core of a long job advert. A direct seller can pull the real numbers out of a compensation plan before a meeting. Someone learning German can paste a letter from an office and see which sentences matter most, then read those slowly.
Languages
The tool detects the language of your text on its own. It has full word lists for English and German, including umlauts and German date formats. Spanish, Portuguese, French, Hindi, Punjabi, Urdu, Arabic and Hinglish work with shorter lists, so results there are usable but rougher. Urdu and Arabic are shown right to left. The buttons and labels can be switched to all ten languages with the menu above the text box.
Your privacy
Your text is processed in your browser. It is not uploaded, stored or logged, and no outside service sees it. Summaries are only saved if you tick "Keep my recent summaries", and then only in your own browser. Sharing happens only when you tap a share button yourself. Read the full privacy note for this tool.
