On this device
Sound, feedback, and memory
Sounds and haptics
A quiet tap, a short buzz, and a chime when a step lands. Off on this device only.
Sound
Four quiet sounds, only when you press something: the chip, a card turning, a thing kept, a page sent.
Datumly remembers
Datumly keeps your calibration and the names of pages you made on this device to coach your own gaps, never your picks or Field Book.
Count toward the Index
Count my Table hands toward the monthly Datum Index of how well people judge AI, in totals only and never by name.
