Syncroll: Split View Sync Scroller

Sync scroll between two tabs in Chrome's Split View. Works on websites, chat UIs, and canvas apps like Figma.

Syncroll keeps two side-by-side tabs scrolling in sync when using Chrome's native Split View feature. HOW IT WORKS Open two tabs in Split View, click the extension icon, and hit "Sync Split Panes". Scroll either side — the other follows. SUPPORTED PAGE TYPES • Normal websites — syncs by scroll percentage, so pages of different lengths stay aligned • Chat UIs (ChatGPT, Gemini) — detects the inner scrollable container automatically • Canvas apps (Figma, Miro, Excalidraw) — relays wheel events for pan/zoom sync Any combination works: a normal website on the left and Figma on the right, two chat windows, etc. PANE DETECTION The extension automatically finds your Split View tabs using Chrome's splitViewId API, highlighted tab status, or adjacent tab index as a fallback. PRIVACY This extension does not collect, store, or transmit any user data. All scroll synchronization happens locally between your tabs through Chrome's built-in message passing. No external servers are contacted.
