  • AI that stays on your computer

    In Chrome on a computer, Okaysize uses the AI model built into the browser to write the summary. It runs locally: your document is never sent to an AI company. The first time, Chrome downloads the model once.

  • Works in every browser

    Without built in AI, Okaysize picks the document's most important sentences instead, by measuring which ones share the most with everything else. Those key points are the document's own words, so nothing is invented.

  • Download the summary

    You get a one page PDF with the key points, what the document covers, and how long it would take to read in full.
