How to use it
- Paste your text, or open a TXT, DOCX or PDF file.
- Choose a length: short, medium or long.
- Read the extracted key sentences and keywords, then copy or download them.
- In desktop Chrome, click Create AI summary for a summary in the AI's own words.
Two kinds of summary
Extractive summary (works everywhere): the text is split into sentences, topic words are weighted, and the TextRank algorithm ranks each sentence by how strongly it connects to the rest of the text. The top sentences appear in their original order, with near-duplicates removed. Nothing is invented or distorted, because every sentence comes word for word from your text – but nothing is reworded either.
AI summary (desktop Chrome 138+): Chrome ships an on-device model, Gemini Nano. When it's available and your text is in English (or Spanish, German, French or Japanese), the tool can summarize in its own words as key points or a TL;DR. The first use downloads the model once; after that it runs offline on your computer. No paid server AI is involved.
Tips for better summaries
Clean input gives cleaner output: remove navigation menus, ads and reference lists before summarizing. Separate sections with blank lines so the summarizer sees the structure. For very long documents, summarize chapter by chapter. AI summaries can make mistakes, so check names, numbers and dates against the original before you rely on them. For PDFs with page references, use the PDF summarizer.
Frequently asked questions
Is this summarizer free?
Yes – no account, no word limit and no paid AI behind it.
Is my text uploaded?
No. The extractive summary runs in your browser and Chrome's AI runs on your device. Your draft is kept in this browser only.
Why don't I see the AI summary option?
It needs desktop Chrome 138 or newer with the built-in AI available, and text in a supported language. Everywhere else you get the extractive summary.
Does it paraphrase?
The extractive summary doesn't – it quotes your key sentences. The AI summary writes its own sentences.
