What it does

• Words that travel. As you zoom, every word that stays slides to its new place and the rest fade around it.
• Zoom under your fingers. Stop halfway, turn back, or open one paragraph alone.
• Beside the original. Open a paper's or a PDF's own pages next to the text, each paragraph shown where it stands on its page.
• Ask AI about exactly what you read. Select a passage, or ask about the whole text: the short answer comes first, and each point links to the paragraph it rests on. With Look it up on the web, an agent on your computer searches the web too.
• Your language. Read in many languages, translated sentence by sentence, with every formula as typeset. A document's own levels are written in its own language.
