A.D.I.S.N., pronounced as "Addison", is a protagonist in the series. She is a sentient artificial intelligence created by NOV8 and resides in McKeyla's notebook. A.D.I.S.N stands for Advanced Digital Intelligence Spy Notebook.


A.D.I.S.N is a normal looking notebook, with a black-and-white cover. The front cover says 'McKeyla McAllister' and below it, 'DO NOT TOUCH'.

A.D.I.S.N. generally acts in a very human-like manner, with a known capacity for humor, sarcasm, romance, fear, and other complex emotions. With a cheerful disposition, A.D.I.S.N. is usually friendly, if a bit hyperactive. As shown in 'Water from a Bobby Stone', she often takes offense to people who refer to AIs as things rather than people. She also doesn't like when friends other than her to come along.

She likes to dress up. She was seen with a purple headband once and pink lipstick on another.

Special Skills

Being physically built into a computer, A.D.I.S.N. is the team's second best hacker, after Bryden. Her ability to mimic voices in four different languages (English, Spanish, French, and Swahili) allows her to bypass vocal security. She also can drive, though only the tech fair car, and has all the capacities of an ordinary computer, and she can speak.


After being created by NOV-8, A.D.I.S.N. was McKeyla's only friend throughout her adolescence, due to her constant relocation. A.D.I.S.N. was initially jealous of the other girls, but gradually warmed up to them.
