How it works

The text of your file is read in your browser. When AI is switched on for this website, the text is sent to Google Gemini, which writes the summary using only facts from your document. Otherwise a quick summary is made on your device by picking the sentences that carry the most important words.

Tips for good summaries

Choose short bullet points for revision notes, a paragraph for emails and reports.
Ask for the summary in Urdu or another language to understand an English document faster.
Always check important numbers, names and dates against the original document.

Frequently asked questions

Is it free?

Yes – free. You only need a free account – no payment, no watermark and no daily limit.

Is the summary accurate?

It is written only from your document, but a computer can still miss nuance – check important facts in the original.

How long can the document be?

Up to about 18,000 words are summarised at once; longer texts are shortened to that.

Is my document uploaded?

Your file is read on your device. For the AI summary only the extracted text is sent to Google Gemini through this website; the quick summary is made entirely on your device.
