How to Calculate
About the AI Text Summarizer
The AI Text Summarizer is a free online tool that condenses articles, research papers, blog posts, and notes into clear, concise summaries — all in your browser. Students use it to extract key points from study materials, professionals summarize reports and emails, and content writers distill source material before rewriting.
The tool uses TextRank, a graph-based extractive summarization algorithm inspired by Google's PageRank. It builds a similarity graph of all sentences, then iteratively computes which sentences are most central to the text. The interactive Sentence Ranking panel gives you full control — every sentence shows its TextRank score, and you can toggle individual sentences on or off to customize the summary in real time.
Beyond summarization, the tool extracts top keywords with frequency bars, calculates readability scores (Flesch-Kincaid Grade Level, Reading Ease, and Fog Index), and computes a summary quality score based on content coverage and diversity. You can listen to the summary with built-in text-to-speech, copy to clipboard, export as .txt or PDF, and restore past summaries from browser history.
Summaries are extracted from text you provide in-session using local heuristics. Paste articles, choose length, and always verify key facts against the source.
