In 1985, 6-year-old Ali began her acting career as a regular child performer on Sesame Street and appeared with Herbie Hancock in a musical number. She also appeared twice on Star Search. She made her breakthrough in 1990, when cast as Ashley Banks for the television sitcom The Fresh Prince of Bel-Air. She sang on various episodes of the show, including a heavily altered version of Aretha Franklin's "Respect" and the original song, "Make Up Your Mind", produced by Robert Jerald of N'Spyre Music Productions. Will Smith asked her if she seriously considered pursuing a musical career. However, despite her singing ability, Ali concentrated on her acting career on The Fresh Prince of Bel-Air. In the series' final season (1995–96), Ali began preparing herself for her musical debut. The result was the album Kiss The Sky, which was certified gold in early 1999. The album spawned the hit song "Daydreamin'", released July 21, 1998, produced by Rodney "Darkchild" Jerkins, which peaked at No. 6 on the Billboard Hot 100 and on the UK Singles Chart.

The album spawned two further UK hits, "Boy You Knock Me Out", featuring Will Smith, which peaked at No. 3 and is her biggest hit to date; and "Everytime", which was her third top 20 hit in the UK, peaking at No. 20. She made an appearance in Smith's album Willennium for the track "Who Am I" with MC Lyte. Along with her musical career, Ali kept acting in many films. She had the chance to work with recognized film directors such as Takeshi Kitano (Brother), Rodrigo Garcia (Mother and Child), among others. In 2005, she completed work on the film Glory Road and starred in the music video for Nick Cannon and Anthony Hamilton's "Can I Live?" as Cannon's mother. In early 2008, she performed on the song "Yes We Can", a will.i.am project supporting Barack Obama's presidential campaign. She also appeared in the subsequent music video which gained coverage on the "What the Buzz" segment of ABC's World News Now.

She also performed the title song, "Sunny Valentine" along with Terrence Quaites for the indie film, Rockin' Meera directed by Param Gill in 2005. In 2009 and 2010 she produced and starred in the BET web show, Buppies. She is currently on recurring status on the CBS soap opera The Young and the Restless as Roxanne. Ali can be seen in the show, Love That Girl! on TV One. She stars as Tyana (which comes from the last five letters of her name).

In January 2014, Ali released a new EP entitled Hello, with her first single "Wait For It", which she also performed on The Arsenio Hall Show on February 4, 2014. In July 2016, Ali sued Warner Bros claiming that the company used her idea for the show The Real after she pitched the concept in December 2012. The case was dismissed in February 2017.

Ali attended Harvard University, where she received a bachelor's degree in African-American studies and Government in 2002. She traveled the United States as a spokesperson for Barack Obama's 2008 presidential campaign and headed voter registration drives at college campuses. In 2012, she continued showing her support.
