Summarise Text Without Uploading It
Condense long text
This will pick out the most important sentences and quote them exactly. For a contract, a filing or anything where a wrong number matters, that is often more useful than a rewrite: nothing can be paraphrased into something the document does not say.
What is Text Summarizer?
Condense long text without sending it anywhere. Where your browser has an on-device writing model, it is used and the summary is written for you. Where it does not, which is most browsers, the tool picks out the most central sentences and quotes them exactly, so every word in the result appears verbatim in your document and no figure, name or date can have been altered. The page always tells you which of the two ran. For a public article a chatbot will write you a better summary; the reason to use this is a draft contract, an unreleased report or a transcript you would not paste into someone else's service.
How do I use Text Summarizer?
- Paste the text you want condensed.
- Choose how long the summary should be.
- Summarise, and check which engine ran.
- Copy the result.
When should I use Text Summarizer?
Use this for text you would not hand to a third party. For a long PDF, use PDF Summarizer, which reads the document directly. To count what you pasted, use Word Counter. To compare two versions of a document, use Text Compare.
Frequently asked questions
Which engine actually runs?
If your browser has a built-in on-device writing model, that writes the summary. Otherwise the tool ranks your sentences and quotes the most central ones. The result panel always says which happened, because the two carry very different guarantees.
What does "quoted exactly" mean, and why is it good?
Every sentence in the output appears word for word in your input; nothing is rewritten or generated. For a contract, a filing or a medical letter that is often more useful than a fluent rewrite, because a paraphrase can quietly change a number, a date or a qualifier. The trade-off is that it reads like excerpts rather than prose.
How are the sentences chosen?
By TextRank. Sentences become nodes in a graph, connected in proportion to how much distinctive vocabulary they share, and PageRank is run over that graph. A sentence scores highly when it is similar to many other high-scoring sentences, which is a good proxy for being central to the document. The chosen ones are then shown in their original order.
Why not use a proper AI model?
Because shipping one would mean a download of several hundred megabytes to a page that should work immediately, and the small models that would fit are trained on news articles and do poorly on contracts and reports. Where your browser already has a model, we use it. Where it does not, an honest extract beats a bad rewrite.
Is this better than pasting into a chatbot?
For a public article, no, and it would be silly to claim otherwise. For anything confidential, yes, and for a specific reason: nothing you paste here leaves the tab. Many employers now prohibit pasting company material into external AI services, and this is the case that prohibition creates.
Why did it refuse my text?
Extractive summarising needs sentences to rank. A list of fragments, a table of values or a handful of bullet points has nothing to work with, and the tool says so rather than returning something meaningless.
Is my file uploaded anywhere?
No. Everything runs in your browser. Your files never leave your device, and there is no server component for this tool.
