No. Summarizing happens entirely in your browser. Your document never leaves your device and is not stored after you finish reading the result.

Thrives with 500 to 5,000 words supplying robust statistical signals. For example, 2,000-word reports at 25 percent deliver balanced briefs. Sub-200-word snippets lack differentiation while 10,000-word tomes may strain mobiles.

Employ 10 percent for executive flashes and 25 percent for detailed briefs. For example, 2,000 words at 10 percent produce 200-word snapshots while 25 percent yields 500-word overviews. Align compression with audience time budgets.

Original sequencing maintains logical causation and anaphora resolution despite extraction of top sentences. For example, shuffled top sentences confuse readers when conclusions precede evidence. Retaining source order ensures introductions precede conclusions for coherent consumption in briefs and study notes consistently.

In-depth guide

What extractive summary keeps

Distill lengthy documents via term-frequency valuation extracting highest-scoring sentences in native order without generative paraphrase for briefs, digests and intros. Process 2,000-word guides at 25 percent producing 500-word condensations spanning 8-10 pivotal lines. Reference table maps ratios: 10 percent equals 200-word flash | 25 percent equals 500-word brief | 40 percent equals 800-word detailed | 500 words minimum input | 5,000 words maximum smooth. Example one briefs research: 2,000-word climate report at 25 percent surfaces methodology and findings. Edge handling strips boilerplate headers, normalizes case and ignores image captions. Students outline chapters, managers triage reports and creators seed descriptions systematically.

How frequency ranking selects

Lexical scores accumulate per occurrence excluding stopwords the and, sentence totals sum constituent weights, top N survive ordered for readability. Twenty-five percent of 2,000 words isolates 8-10 representative statements. Example two digests manual: 3,000-word handbook at 20 percent yields 600-word operational essentials preserving warnings. Edge intricacies involve tie scores resolved by earliest appearance, quoted passages overweighted by repetition and headings skewing tallies. Exclude navigation chrome before analysis, calibrate ratios iteratively and archive source-summary pairs every cycle. Analysts compare versions, researchers validate coverage and editors prune redundancies.

Summary worked example: 2000 words 25 percent to 500 words

Load 2,000-word guide, designate 25 percent, generate ordered top sentences near 500 words, duplicate for briefs. Extractive scope omits paraphrase, abstraction and stylistic rewriting; verbatim sentences only. Very short inputs underperform statistically. For total word sentence and reading-time verification complementing brevity planning, continue with our length counter at /word-counter to assess scope accurately.
