Sync scrolling across multiple browser tabs with a single click.
Select the tabs you want and scroll them together to compare documents, translations, or code side by side.

How It Works
Open the extension, select the tabs you want to sync, and click Start Sync.
When multiple tabs share the same URL, the extension can suggest syncing them.



Features
• One-click tab synchronization
• Scroll multiple tabs together
• Adjust a single tab position using the Alt key
• Sync suggestions for tabs with the same URL
• Automatic reconnection if sync is interrupted

• Google services (Docs, Drive, Gmail, Sheets, Slides, etc.)
• Web apps such as Figma, JIRA, and Notion
• Browser internal pages and extension stores
• Search engine result pages
• PDF files and PDF viewers
• Login and authentication pages
• Special URLs such as file://, view-source:, or data:



Privacy
