Open your websites
Enter any website URL or bring the current page into the sidebar.
Work your way
Keep your familiar tools alongside to read, ask, research or get things done.
Switch tabs. Keep going.
Share a sidebar in one window, or bind it to a tab when needed.
Less switching. More focus.
Favorite shortcuts
Welcome-screen icons wrap into rows. Hover for the title and full URL.
Save a favorite
Use More in the sidebar, or right-click a webpage or the extension toolbar icon.
Find your way back
Reopen up to 10 recent pages. Remove entries or clear recents while keeping favorites.
Make it yours
Mobile or desktop view. Light, dark or system appearance.
Close the current page
Return to welcome while keeping favorites, recents, bindings, and other side pages.
Keep it local
Favorites, recents, and preferences are shared across windows and survive restarts on your device.
One shared sidebar.
Or one for a tab.
Keep a reference beside your reading tab, or an AI page beside your writing tab. Come back and pick up where you left off.
Shared by default
All unbound tabs in the same window share one sidebar page. Switch tabs and keep your side page running.
Bind when you need to
In the sidebar’s “⋯” menu, choose “Bind to current tab” to give that tab its own page. Your input, scroll position and browsing history stay in place as you switch tabs.
What happens to the other tabs?
The current page and its history move to the bound tab, leaving the shared sidebar empty. Other unbound tabs show the welcome screen until you open a new shared page.
Unbinding releases the dedicated page and returns to the current shared page. Closing the bound tab or restarting the browser also clears the binding.
Your next page.
