Text summarizer: the key points of any English text

How to use Text Summarizer

1. 1Paste or type the English text you want summarised, up to 1,200 words. Or tap "Try an example".
2. 2Tap "Summarise". The first time, the AI (about 480 MB) downloads once and stays on your device; after that it starts in seconds.
3. 3Read the 3 to 5 key points. Under each one is the sentence of your text it comes from, and any figure that is not in your text is marked.
4. 4Untick the points you do not need, then copy the summary, save it as a .txt file or share it.

Why use Text Summarizer

Every point with its source

Each key point is shown with the sentence of your text that supports it, matched by the words they share, so checking a summary takes seconds instead of rereading the whole text.

Measured, not promised

On 50 notices, articles, emails and meeting notes we wrote for the test, 41 summaries (82 %) had every point supported by the text. The rest had one point that was wrong or added, which is why the sources are shown.

Private: the text stays on your device

The summarizer is an AI model (Qwen3-0.6B, Apache 2.0) that runs in your browser on the graphics chip. Nothing you paste is sent anywhere.

Figures checked for you

A point that contains a number, date or amount that is not in your text is marked "Check this figure", the most common way a small model gets a summary wrong.

One job, done the same way

No chat box and no prompt to write: the summarizer always gives 3 to 5 short points, most important first, in the order a reader needs them.

Works on a computer with a recent browser

It needs WebGPU, which recent Chrome and Edge on Windows, Mac and ChromeOS have, and Safari 26 on a Mac. On a laptop with built-in graphics a summary takes about 5 seconds.

About this tool

A summary is useful when a text is long and you need to know what it says before you decide what to do with it: a circular from your child's school, a notice from the building management, a news article someone forwarded, the minutes of a meeting you missed, or a long email thread. This summarizer reads the text and writes 3 to 5 short bullet points with the main facts, the most important first: what is happening, when, where, how much, and what you are asked to do. It keeps names, dates and figures as they are written, and it does not add opinions or outside facts on purpose.

It is a small AI model, and small models make mistakes. In our test on 50 English texts, 9 summaries had one point that was not supported by the text: a time span shortened, a reason invented, or who did what swapped. That is why the tool shows the sentence each point came from and marks any figure that is not in your text. Read the points against their sources before you rely on them, especially for anything legal, medical or about money. The summarizer works on English text; for Arabic or Urdu text, translate it to English first or use the word counter. It runs on the graphics chip of a computer, so it needs a recent Chrome, Edge or Safari; phones are not supported yet because the model needs more memory than most phones give a web page.
