核心要点 (BLUF)： Free online Web & PDF summarizer in your browser (online in your browser): instantly extract key takeaways, executive summaries, and essential facts from articles, research papers, reports, and PDF documents. Runs 100% on your device with complete privacy and zero token charges.
Paste any article text, web page content, or drag and drop a PDF, TXT, Markdown, or HTML file. The tool instantly extracts raw text, strips boilerplate markup, and segments content into semantic sentences.
Graph-theoretic TextRank centrality and term frequency scoring (TF-ISF) identify the most informative sentences, while Maximal Marginal Relevance (MMR) eliminates redundancy to produce a crisp, coherent summary.
Choose between four specialized summary modes: Executive Summary (2–3 sentences capturing the primary thesis), Key Bullet Points, Metrics & Insights (highlighting numbers, decisions, and action items), or a Comprehensive Review.
Tailor compression ratios from concise (15%) to detailed (50%), inspect extracted keywords, and export results directly as Markdown (.md) or plain text (.txt).
All computations—from PDF stream parsing to graph centrality ranking—occur entirely inside your browser sandbox on your local CPU. Your private documents, financial statements, and research files never leave your machine.
The tool is completely free forever, requires no login, and charges zero tokens.
Yes. It executes entirely in your browser without requiring an account or spending any tokens.
You can upload PDF files with a text layer, plain text (.txt), Markdown (.md), HTML web pages, or paste any copied article or text directly into the tool.
No. All text parsing, indexing, and summarization happen exclusively inside your browser on your device. Zero bytes leave your machine.
Because processing is on-device, you can summarize both short memos and extensive multi-page reports. We recommend PDF files up to 50 MB for smooth browser performance.
