AI Text Summarizer Pro
Summarize long articles, documents, and any text in seconds. Extract key sentences while preserving the original meaning.
How It Works
The AI Text Summarizer uses an extractive summarization algorithm that analyzes your text at the sentence level. It first splits the text into individual sentences, then calculates a relevance score for each sentence based on word frequency analysis — words that appear more frequently across the document are considered more important.
Each sentence is scored by summing the frequency weights of its words (excluding common stop words), and the top-scoring sentences are selected to form the summary. The compression ratio slider lets you control how much of the original text is retained — lower percentages produce shorter, denser summaries while higher percentages include more context.
This approach works best for factual, informative texts like news articles, research papers, and documentation. Since everything runs client-side, your text never leaves your device.
