Read Panes

View and compare multiple pages side by side for faster research.

Research means reading several sources at once — but Chrome only shows you one page at a time, so you end up alt-tabbing between articles and losing your place. Read Panes puts 2 to 4 web pages side by side in a single Chrome window so you can read, scroll, and compare them without switching tabs or windows. Compare pages side by side in 1×2 or 2×1 layouts for free, or unlock more grids (1×3, 3×1, 2×2, and 1×4) with Pro so you can line up two articles, three sources, or four references at once. Open any URL in each pane's address bar, or pick a page straight from your open tabs to drop it into the split view. Switch layouts in one click to match the way you're reading — two columns for a deep comparison, a 2×2 grid for a quick survey (Pro), or four across for skimming (Pro). Save sessions of the pages you had open and restore the exact set of panes later, so you never lose a research thread. Resize panes with draggable dividers and let Read Panes remember each layout's URLs (Pro). How it works: Click the Read Panes icon or press Alt+Shift+R to open the split reader in a new tab. Pick a 1×2 or 2×1 layout (or unlock 2×2, 1×3, and more with Pro) and type any URL into each pane's address bar, or choose a page from your open tabs. Read and scroll all panes together; press Alt+Shift+S to save the session and reopen the same pages later. Read Panes runs entirely in your browser. Saved sessions and pane URLs are stored locally in your extension storage and never uploaded. The only server requests verify your Pro status or power the checkout flow. Read Panes does not sell your data, and each pane's content loads directly between your browser and the site you opened. Read Panes is for researchers comparing sources, students cross-checking references, writers verifying several citations, and analysts scanning multiple reports at once.
