The notebook's main ability is to manipulate the future events to his desire just by writing or speaking a short description of it. This ability is powerful enough to influence both humans and inanimate objects alike, as well as cancelling a Time Jacker's temporal freezing. When influencing humans, the target in question has no awareness of what they were doing until the event was completed. However, this ability can be countered if an opponent stops Woz from writing or turning on the voice recognition system. The Future Note possesses a major drawback in the fact that vague wording or ambiguous syntax can create loopholes which others can exploit. This allowed Black Woz to steal his Kamen Rider powers with the aid of Heure and Hiryu Kakogawa, thanks to White Woz losing the Miridewatch and trying to reclaim it by writing "The powers return to Woz" in the Future Note without specifying which Woz.
- The Future Note is a reference to the popular manga/anime Death Note, which features a mystical notebook that allows its owner to kill another person by writing down the cause of their death inside it.
- The Future Note is left unnamed throughout the entire show until it is mentioned by Daiki Kaito in episode 29.
