Text Summarizer
Pick out the key sentences from a long text, locally
Condense a long piece of text down to the sentences that carry the most weight, using a local, deterministic ranking algorithm. Choose how many sentences to keep; the result is made only of sentences copied from your original text.
This is extractive summarization: it selects and reorders the most representative sentences from your own text. It does not paraphrase or generate new sentences, and it is not an AI language model.

What this tool does
This tool splits your text into sentences, scores each one by how many frequently repeated, meaningful words it contains, and keeps the highest-scoring sentences up to the count you choose, presenting them back in their original order. This is extractive summarization: every sentence in the result already existed in your text, unchanged. It does not generate new sentences, paraphrase, or use a language model — it only selects and reorders.
How to use it
- Paste or type the text you want to summarize.

Frequently asked questions
- Does this use AI to write the summary?
- No. It ranks and selects existing sentences from your text using a local word-frequency algorithm; it does not generate new wording or call any AI service.
- Why does the summary include an odd sentence?
- The ranking favors sentences with words that repeat often across the text, plus a small boost for the opening and closing sentences. A sentence can rank highly by that measure even if a human editor would have chosen differently.
- Is my text uploaded to summarize it?
- No. Splitting, scoring and selecting sentences all happen in your browser.
