Example numbers. Your savings depend on your tabs.

  1. The problem

    1,284 tabs. 9.6 GB of memory. 4 hours of battery. Zero of them read.Every open tab keeps a whole page alive in memory. Away from the plug that is hours of battery you never get to use.

  2. One click

    Battery at 41 percent. Press the trunk.TabTrunk sees every Safari window and every tab. One button packs them all away, before the battery does.

  3. One click

    Every tab goes into the trunk.Each tab lifts off its window and is kept with its title, its address and the window it came from.

  4. One click

    Safari breathes again. Hours more battery.No crowded windows, no tab bars, memory freed, a cooler Mac. On the road your MacBook runs from 4 hours to 12, and your tabs wait in the trunk until you need them.

  5. How it works · the library

    Grouped like your windows.Open TabTrunk and every window you had is a group, so the way you worked is still there tomorrow.

  6. How it works · the library

    Sorted by topic. ProApple Intelligence reads the titles and sorts them into topics, on your Mac.

  7. How it works · the library

    Every tab gets a one-line summary, written on your Mac. ProFind a tab by what was on it, not by a title you no longer remember.

  8. How it works · find it again

    Search it, or just ask. ProSearch titles, page text and meaning. Or ask: "What did I save for my trip that I still haven't read?" It answers from your own tabs and shows where each answer came from.

  9. How it works · hints

    It taps you on the shoulder. ProTell it what you work on. When a tab in the trunk fits, a Mac notification says: look at this one, and why.
