How much can I paste in at once?

Up to twenty-four thousand characters, roughly four thousand words or a dozen pages. That covers most articles and reports whole. For a book chapter or a long transcript, summarise each section and then summarise the summaries — the result is usually better than one pass over the lot, because nothing has to compete for attention.

Will it add things the document does not say?

It is instructed not to, including background it might happen to know about the subject, and including implications the author stopped short of drawing. The failure mode to watch for is subtler: a summary that is a shade more certain than its source. Compare the hedging in both if the conclusion matters.

Does it work on meeting transcripts?

Well, and better with the key points shape than with bullets. Transcripts bury decisions inside conversational back-and-forth, and pairing each decision with the reasoning that produced it is more useful than a list of topics that came up.

Can I summarise a PDF here?

Not directly — this box takes text. Use the PDF text extraction tool first, which runs entirely on your own machine, then paste what it gives you. The PDF itself never has to leave your device that way; only the text you choose to paste does.

Where this one is different

Every other tool on this site does its work inside the tab you have open. Files are read by your own browser, nothing is uploaded, and the page keeps working with the network disconnected. That is not true here. The AI tools need a language model, a language model is far too large to run in a browser tab, so the text you put in the box is sent to our server and passed to an AI provider to be worked on.

What is sent is the text you typed and the settings you chose. Nothing else — no file you have used elsewhere on this site, no record of other tools you have opened, and no identifier, because there are no accounts here to identify you with. Your text is not written to any database, log or file that we keep. The provider’s own retention is the provider’s, which is the honest limit of what anyone can promise about text sent off a device.

So the practical advice is the plain one: do not paste anything here you would not paste into someone else’s website — client data, credentials, unpublished work, medical or legal details. For everything else, use it freely. And read what comes back: it is generated, it can be wrong, and it is confident either way.

About the Text Summariser

A summary that opens with "this article discusses" has wasted its first and most valuable sentence. The point of shortening something is to put the conclusion where the reader will find it, and a summary that describes what a document is about rather than what it says leaves you exactly where you were: knowing there is something in there and not what.

So this page is built to lead with the finding, whatever text you give it. The board rejected the merger. Latency fell by a third after the migration. The trial found no difference between the groups. Whatever the piece concluded goes first, and the supporting material follows if there is room.

Four shapes are on offer and they suit different jobs. A paragraph reads best when you intend to actually read it. Bullets work when you are scanning a stack of documents and want to compare them. One sentence is for a subject line or a decision about whether to open the thing at all. Key points, which pairs each claim with the detail behind it, is the one to use when you will be relied upon to have understood the document rather than merely skimmed it.

The length slider is separate from the shape, because the two are independent: a bulleted summary can be terse or generous, and so can a paragraph.

Certain things are kept on purpose. The numbers that carry the argument keep their units and their period, since a figure without either is not evidence. Uncertainty is preserved — a source saying early results suggest does not become a source saying research shows, which is the single most common way a summary ends up more confident than the thing it summarised. Anything not in the original stays out, including relevant background you might reasonably expect a reader to want.

Turn on the quoted lines when you will need to defend the summary, or paste it somewhere the exact wording matters.

How to use it

1Paste the article, report, transcript or email thread into the box.
2Choose a shape: a paragraph to read, bullets to scan, one sentence to file, or key points to be examined on.
3Set the length slider — low for the bare finding, high to keep the supporting detail.
4Turn on the quoted lines when you need the source's exact words alongside the summary.
5Check the summary against the original for confidence: it should hedge wherever the source hedged.
