Need the short version of a long article, report or set of notes? Paste the text into this free text summarizer and it picks out the sentences that matter most, then hands you a short summary and a list of key points. We should be upfront about how it works. It isn't ChatGPT, and it isn't any other large language model. It uses a classic extractive method: it counts which meaningful words come up most often, gives each sentence a score based on those words, and keeps the sentences with the highest scores, in their original order. That means it never makes up facts or rewrites what you gave it. It only pulls out sentences you already wrote. Because it runs in your browser, your text never leaves your device, which is handy for private drafts and work documents.

It's an extractive algorithm, not an AI chatbot. It doesn't paraphrase or check facts. For summaries that understand context, try ChatGPT, Claude or Gemini, and always double-check anything important.
How to use the text summarizer
- Paste your text into the box. Longer pieces work better, ideally 300 words or more with full sentences.
- Set the length with the slider. At 30%, about a third of the sentences are kept.
- Click Summarize. You'll get the summary paragraph, the top key points and a word count showing how much shorter it is.
- Click Copy summary to paste it into notes, an email or a document.
It works best on news stories, blog posts, study notes and reports. It struggles with poetry, dialogue, tables and bullet lists that don't use full sentences. Students might also like our NotebookLM study guide, which explains how to summarize your own sources with AI.
FAQ
Is this an AI summarizer?
It's an automated summarizer, but not a generative AI. It uses word-frequency scoring, a well-known natural language processing technique, rather than a large language model, so it can't invent anything.
Is my text private?
Yes. Everything runs in JavaScript on your device. Your text isn't uploaded, saved or sent to any server.
How long can the text be?
There's no hard limit. Tens of thousands of words should still summarize in under a second on most phones and laptops.
What's the difference between extractive and abstractive summaries?
An extractive summary copies the most important sentences word for word. An abstractive summary, like the ones ChatGPT writes, rewrites the ideas in new words. Extractive summaries are safer from errors but can read a little choppy.
Does it work in other languages?
It's tuned for English. Other languages that use full stops still work, but the results are weaker because the list of filler words it ignores is English-only.
