Instant key-sentence summary (no AI, stays in your browser)
This mode is extractive: it keeps the most important sentences word for word. Each sentence gets a score from how many of the passage’s most frequent meaningful words it contains (words like “the” and “of” are ignored), the opening sentence gets a small boost, and the top scorers are kept in their original order. It is the same basic idea as H. P. Luhn’s 1958 automatic abstract method at IBM.
The AI summary above is abstractive: it writes new sentences. Toggle “Show why” to see how each sentence scored.
Frequently asked questions
What is the difference between the AI and key-sentence summaries?
The AI summary is abstractive: it writes new sentences that condense the text. The key-sentence summary is extractive: it scores every sentence by how many of the text’s most frequent important words it contains and keeps the top ones, word for word, in their original order. The extractive mode runs instantly in your browser and never sends your text anywhere.
How long can the text be?
The AI summary accepts up to 6,000 characters per request. The key-sentence mode has no practical limit because it runs locally.
Can I summarize a web article?
Copy the article text from the page and paste it in. We do not fetch URLs, which keeps the tool private and avoids paywall problems.
Should I cite a summary?
Yes. A summary restates someone else’s ideas, so academic styles such as APA and MLA still require a citation to the original source.
Is the text summarizer free?
Yes, free with no signup and no stored text.
