In order to reproduce a copied technique, however, one must have the necessary skill or ability to perform them. The user can memorise ninjutsu, genjutsu, and taijutsu with near perfect accuracy, allowing the user to use the techniques as their own, or even modify them to create their own new techniques, much like Sasuke Uchiha's Lion Combo.

The Sharingan's third and most well-known ability is that it grants the user the ability to memorise almost any technique that he or she witnesses, apart from other kekkei genkai techniques. However, even though the user may be able to see an attack or know it is coming, their body may not always have time to react. As the Sharingan evolves, gaining more tomoe seals, this ability extends to being able to track fast-moving objects before finally giving some amount of predictive capabilities to the user, allowing them to see the image of an attacker’s next move from the slightest muscle tension in their body and counterattack or dodge without any wasted movement. This also allows the user to pick up on subtle details, enabling them to read lip movements or mimic something like pencil movements. The Sharingan's second-most prominent ability grants the user an incredible clarity of perception, allowing them to easily recognise genjutsu and different forms of chakra, though not to the same extent as the Byakugan. The Sharingan can tell if a person is under a genjutsu because the person's chakra flow would be irregular.

The first of the Sharingan's powers is being able to see the flow of chakra.

The Sharingan's abilities consist of two parts: the 'Eye of Insight' (洞察眼, Dōsatsugan) and the 'Eye of Hypnotism' (催眠眼, Saimingan).
