Tab overload calculator
Twenty tabs is not a to-do list. This calculator turns a count into a rough memory working-set and the minutes you burn re-orienting — then points at Focus Sessions.

MB used in estimate
150 MB per tab is a conservative Chromium working-set, not a profiler. 25 seconds per tab is the attention tax of coming back to a window. Park the window as a Focus Session instead of keeping it warm.
Then import the useful bits
These tools do not create a Markwise account. When you want the file in a library you can ask, start free and use bulk import on Pro. The file you just inspected is still on your machine.
