Text Summarizer
Summarize long text instantly — extractive summarization, no sign-up
About Text Summarizer
Our Text Summarizer uses extractive summarization to condense long text into shorter versions while preserving the most important information. Unlike AI-based tools, this summarizer works entirely in your browser and does not send your text to any server.
How It Works
- Word Frequency Analysis: Sentences containing frequently used (important) words score higher.
- Position Scoring: Sentences near the beginning of the text are weighted more heavily, as they often contain key information.
- Length Filtering: Very short or very long sentences are penalized to produce a balanced summary.
- Top Sentence Selection: The highest-scoring sentences are selected and presented in their original order.
Frequently Asked Questions
Is my text sent to a server?
No. All processing happens in your browser using JavaScript. Your text never leaves your device, making this tool completely private and secure.
What is extractive vs abstractive summarization?
Extractive summarization selects and extracts existing sentences from the text. Abstractive summarization (used by AI tools) generates new sentences that paraphrase the original. This tool uses extractive summarization.
How long should my input text be?
For meaningful summaries, we recommend at least 5-10 sentences. The tool works best with longer content like articles, reports, and essays.
