Some thoughts arrive faster than you can type
Crosstalk is a notebook you talk to. When an idea shows up mid-walk, mid-drive, or two minutes before a meeting, opening a text editor is the fastest way to lose it. Hitting record isn't.
The name is borrowed from electronics, where crosstalk is the signal that bleeds from one trace into the one beside it — roughly what happens when you think out loud and one idea sets off another.
