Google Keep is a very good shortcut
Need to remember a gate code, packing list, address, shopping item, idea, or a number someone just texted you?
Keep is fast. Make a note, pin it, label it, search it later, add a reminder, share it with someone.
That simplicity is the point.
The workaround appears when the note came from a document
A passport number in a note is useful until you also need the expiry date.
Then the exact spelling of the name.
Then a photo of the passport.
Then the original document for check-in or verification.
At some point the note becomes a second copy of information that already had a source.
Panza keeps the shortcut and the source together
The card is the quick layer. The document stays behind it.
That means you can reach the passport number without losing the passport, or see the insurance policy number without turning the note itself into a miniature filing cabinet.
Keep wins when the source does not matter
Shopping list? Keep.
Reminder? Keep.
Random idea? Keep.
Shared checklist? Keep is built for that.
But when the information belongs to an important document and you may need to prove, inspect, or reopen that source later, Panza gives the shortcut somewhere to point back to.
