Frequently asked questions
How does the summarizer work?
It uses extractive summarization: it counts how often each meaningful word appears, scores every sentence by the frequency of the important words it contains, and keeps the top-scoring sentences in their original order. It picks the most representative existing sentences rather than writing new ones.
Is it as good as an AI summarizer?
Different. AI summarizers rewrite in their own words and can capture nuance, but they send your text to a server and can invent details. This tool selects your actual sentences locally, so it's private, instant, and never fabricates — but it works best on well-structured prose and won't paraphrase.
Is my text uploaded?
No. The whole process runs in your browser, so your text never leaves your device. That makes it safe for notes, drafts, and documents you'd rather not paste into an online AI service.
About this tool
Text Compactor summarizes long passages by extractive summarization: it scores each sentence by how many of the text's important, frequently-used words it contains, then keeps the highest-scoring sentences in their original order. A slider lets you choose how much to keep, from a tight 10% skim to a fuller 90%. It runs entirely in your browser with no AI and nothing uploaded, so it's instant and private. Because it selects existing sentences rather than rewriting, it works best on clear prose like articles, reports, and study material.
Like most tools on UtilityBase, the text compactor runs entirely in your browser — nothing you enter is uploaded or stored on a server. It's free to use with no account required. Browse more text tools here.
