About the startup
Split-view PDF reader in the browser. Same file, two independent panes — read a clause while you keep the definition, a paper while you keep the figure. No account. The file never leaves your machine. Read one point. Reference another. Without losing your place. Why not Acrobat Acrobat’s split is synced. Window > New Window is two windows. This is one window. Each pane keeps its page, zoom, and scroll. Who it is for Long contracts, specs, and papers — two places far apart, both have to stay put. Why it’s this small Nothing to install Independent scrolling by default; link panes only when you compare Layout and reading position are saved Free. English and Japanese. No reading analytics Not an editor. Not Organize Pages. Not a document platform. Open the app
