Tidy Notes vs InkCalc

A notepad you can write in and then forget about. The moment you save, on-device AI reads the note, decides what it is — to-do, shopping, event — and adds tags and a one-line summary. You never file anything yourself. You can find a note without remembering the words you used. Search for "the thing I was supposed to hand out at last week's meeting" and it comes up. Nothing you write is sent anywhere. No account, no network. It works the same in airplane mode.
