About Text Summarization
Reading long articles or documents can be time-consuming. Our Text Summarizer helps you extract the most important information from a text in seconds. This tool uses an extractive summarization algorithm that identifies key sentences based on word frequency and importance.
How it works: The tool analyzes the frequency of every word in your text (excluding common "stop words" like "the", "and", "is"). Sentences containing the most high-frequency words are ranked as most important. Based on the percentage slider you choose, the top-ranked sentences are presented as the summary.
Frequently Asked Questions
Is this an AI summarizer?
It uses a statistical algorithm (extractive summarization), not a generative AI like ChatGPT. It picks existing sentences rather than writing new ones.
Is it accurate?
It is excellent for factual articles and essays where key points are repeated. It may be less effective for creative fiction.
Is there a word limit?
There is no strict limit, but extremely large texts (books) might slow down your browser.
Is my text private?
Yes, the summarization happens entirely in your browser using JavaScript. No text is sent to our servers.
