Add text, upload a file, or paste a URL or YouTube link — then choose a mode and hit Summarize.
An AI summarizer reads a long piece of content — an article, research paper, document, email thread or video transcript — and automatically produces a shorter version that keeps the most important ideas. Instead of reading thousands of words, you get the key points in seconds, structured the way you need them.
This summarizer is extractive: it scores and ranks the actual sentences in your source, then assembles the highest-signal ones into a faithful, fact-accurate summary. Because it never invents new wording, the output stays true to the original and avoids the hallucinations a chatbot can introduce.
Everything runs entirely in your browser — nothing is uploaded — so it is safe for confidential reports and proprietary documents. Pair it with the AI Paraphraser to put ideas in your own words, or the Grammar Corrector to polish them.
Type or paste text straight into the editor, drag and drop a document (PDF, Word, RTF, ODT, Markdown, EPUB and more), paste a web page URL, or drop in a YouTube link. The tool reads everything locally — extracting text from files, pulling readable content from articles, and fetching captions from videos — with live word, sentence and reading-time counters as it loads.
Pick from 22 purpose-built modes — Standard, Bullet Points, Executive, Academic, Student Notes, Meeting, Legal, Medical, News and more — then set how condensed you want the result using the length slider (anywhere from a tight 10% down to a thorough 90% of the original). Each mode reshapes structure, tone and detail to match its audience.
Refine the output with precision controls: preserve facts, dates, statistics, names and direct quotes; surface action items, key insights and risks; bias the summary toward a focus keyword; choose paragraph or bullet output; and set the target language. The extractive ranking engine re-scores sentences instantly as you adjust each option.
Read the summary alongside auto-extracted keywords, named entities, dates and numbers, plus content insights like sentiment, readability and complexity. When it looks right, copy it with one click or export to TXT, Markdown, HTML, PDF, DOCX, JSON, CSV and more — all without a single byte leaving your browser.
One engine, twenty-two voices — Standard, Short, Detailed, Bullet, Executive, Academic, Research, Student Notes, Meeting, Business, Technical, Legal, Medical, News, Blog, Book, Chapter, Email, Podcast, Video, Simplified and Child-Friendly. Each mode reshapes structure, tone and depth for its audience.
Summarize plain text plus TXT, PDF, DOC, DOCX, RTF, ODT, Markdown, CSV, JSON and EPUB files, any web page URL, YouTube videos via captions, scanned pages through built-in OCR, and even spoken audio — all read and parsed directly in your browser.
A single slider takes you from a one-line gist to a rich multi-paragraph digest, targeting anywhere from 10% to 90% of the source length. Get exactly as much — or as little — detail as the job needs, every time.
Lock in what matters: preserve facts, dates, statistics, names and direct quotes, then optionally surface action items, key insights and potential risks. Bias the summary toward a focus keyword and choose bullet or paragraph output for a result tailored to your task.
Beyond the summary, the tool pulls out the signal: top keywords and key phrases, named entities (people, organizations and places), important dates and the numbers and figures that carry the facts — ready to copy into notes, reports or research.
Understand the source at a glance with automatic analysis of sentiment, readability grade, language complexity, document category and topic clusters — a quick, data-driven read on what you are summarizing before you ever scroll the original.
Send your summary anywhere: copy to clipboard or export to TXT, Markdown, HTML, PDF, DOCX, JSON, CSV and rich text. Summaries, extracted keywords and insights travel together so nothing is lost between the tool and your workflow.
Every step — file parsing, OCR, sentence ranking, extraction and export — runs locally on your device. Your documents, articles and transcripts are never uploaded, logged or stored, so even confidential and proprietary material stays completely private.
Summarize far more than plain text. Drop in documents, point at a web page, paste a YouTube link, or scan an image — every format is read and parsed directly in your browser.

Extractive ranking. The engine splits your content into sentences, cleans away boilerplate, then scores every sentence for importance. Rather than rewriting your text, it selects the highest-signal sentences — which keeps the result faithful to the source and free of invented facts.
TextRank & TF-IDF. A TextRank-style graph ranks sentences by how central they are to the document, much like a search engine ranks pages by their links, while TF-IDF weights the words that genuinely distinguish your content from ordinary language.
MMR diversity. Maximal Marginal Relevance favors sentences that add new information over ones that echo what is already included, so the summary covers more ground in fewer words without repeating itself.
Multi-pass chunking & extraction. Long inputs are processed in chunks and summarized across multiple passes, so even a book-length document is condensed without losing the thread. A final pass extracts keywords, entities, dates and numbers — and none of it ever leaves your device.

Because the tool is extractive, it selects and ranks the real sentences from your source rather than rewriting them, so the summary stays faithful to the original and avoids invented facts. Accuracy is highest on well-structured content; for very informal or fragmented text, choosing a longer length or a more specific mode improves the result.
It splits your content into sentences, scores each one for importance using TF-IDF, keyword density, position and named entities, then ranks them with a TextRank-style graph algorithm. A diversity step removes redundancy, and long documents are summarized in multiple passes. No data is sent to any server — the entire process runs in your browser.
There are 22 modes — Standard, Short, Detailed, Bullet Points, Executive, Academic, Research, Student Notes, Meeting, Business, Technical, Legal, Medical, News, Blog, Book, Chapter, Email, Podcast, Video, Simplified and Child-Friendly.

The summary is extractive, meaning it faithfully reflects the source by selecting its most important sentences rather than rewriting them, so it is accurate but not “original” writing. Always cite the original source when you use a summary, and pair it with a paraphraser if you need to express the ideas in your own words.
