Modern day devices, such as phones, can often be used with a stylus to accurately navigate through menus, send messages etc. 
Today, the term ''stylus'' often refers to an input tool usually used with [[touchscreen]]-enabled devices, such as [[Tablet computer|Tablet PC]]s, to accurately navigate interface elements, send messages, etc. This also prevents smearing the screen with oils from one's fingers. Styluses may also be used for handwriting, or for drawing using [[graphics tablet]]s.

Many new phones have a built-in stylus which tucks in behind the back cover. Some styluses may extend and contract into small, pen-like cylinders, which are easy to put away.

Styluses come in both passive and active versions.

A passive or capacitive stylus is a stylus that acts just like a finger when touching a device screen. There is no electronic communication between a passive stylus and a device, and the device treats the stylus the same as a finger. Passive styluses are considered less accurate than active styluses.

An active stylus includes electronic components that communicate with a device's touchscreen controller, or digitizer. Active pens are typically used for note taking, on-screen drawing/painting, and electronic document annotation. They help prevent the problem of one's fingers or hands accidentally contacting the screen.

As in ancient styluses, the stylus is pointed or rounded at one end and is made to fit in the grip of a hand comfortably. These styluses can be found in many different styles.

Since many modern tablets make use of multi-touch recognition, some stylus and app manufactures have created palm rejection technologies into their products. This works to turn off the multi-touch feature allowing the palm to rest on the tablet while still recognizing the stylus.

Other than the types above, a haptic stylus is a stylus that simulates, through [[haptic technology]], realistic physical sensations which can be felt while writing on paper. The sensation is sometimes enhanced by the combination of auditory and tactile illusions, such as with [[RealPen]].<ref>{{Cite web|url=https://doi.org/10.1145/2984511.2984550|title=RealPen: Providing Realism in Handwriting Tasks on Touch Surfaces using Auditory-Tactile Feedback|first1=Youngjun|last1=Cho|first2=Andrea|last2=Bianchi|first3=Nicolai|last3=Marquardt|first4=Nadia|last4=Bianchi-Berthouze|date=October 16, 2016|publisher=Association for Computing Machinery|pages=195–205|via=ACM Digital Library|doi=10.1145/2984511.2984550|arxiv=1803.02307 }}</ref>
