Summarizer
Summarize long text to its key sentences.
Summarizer is a browser-based text tool on TextToolsBase. Summarize long text to its key sentences. To use it, paste or type your text and view the result directly in your browser — no signup and nothing to install.
A summary you can trust should use the source's own sentences, not reworded paraphrases.
Summarizer is extractive: it ranks and selects the most important sentences, with a length slider to set how many.

Good to know
Summarizer scores sentences by how much they share with the rest of the text and selects the top ones, keeping their original wording and their original order. It does not invent or reword anything, so the summary is made of sentences from your source. The length slider controls how many sentences are kept. Very short text returns little to select, and above 500 sentences it summarizes the first 500 with a visible note.
Frequently asked questions
Does it reword the text like a paraphraser?
No. It is extractive: it selects whole sentences from your text and keeps their wording, rather than rewriting them.
What does the length slider do?
It sets how many of the top-ranked sentences are kept, so you can make the summary shorter or longer.
Why are the sentences in the original order?
It preserves the source order so the summary reads coherently and stays faithful to the flow of the text.
Is there a limit on very long text?
Above 500 sentences it summarizes the first 500 and shows a note; very short text has too few sentences to summarize.
