From 1994 to 2003 Kaia was trained by Tiit Kivistik. From 2003 until the autumn of 2007, Kaia was coached by Andrei Luzgin. After Luzgin, Fredrik Lovén from Sweden became her coach, but their partnership ended in February 2008. Kanepi's next coach (until September 2008) was Pablo Giacopelli. From November 2008, she was coached by Luca Appino. After November 2009, Kanepi was coached by fellow Estonia pro Mait Künnap. In February 2010, she broke up with her coach and agent. In April, she started to work with Silver Karjus, who was her coach until March 2012. From 2013–2014, she was coached by Märten Tamla. Kanepi was coached by Dave Marshall and Indrek Tustit.

Kanepi builds up her game around her powerful groundstrokes. Her serve is considered to be one of the strongest on the WTA Tour. Kanepi frequently hits 170 km/h to 180 km/h serves. She generally serves away from her opponent but sometimes prefers to hit a powerful body first serve in order to push back and pin her opponent behind the baseline. But on occasions her serve can break down, which affects her game. In 2008, she began to improve her volleying skills and under her coach Luca Appino begun to use sliced backhand more often, thus making her playing more versatile. She likes to return serves mainly with her backhand which she hits flat and tries to position herself to receive with backhand but is also capable of hitting good service returns with her forehand as well. She generally ends points early but she is capable of playing long rallies and reducing her unforced error count. Overall, she is an offensive baseliner but depending on the game situation and scoreboard Kanepi can play a more defensive game.

For a long time Kanepi was sponsored by Infortar, the largest shareholder of Tallink, a major ferry company in the Baltic Sea. Their sponsorship ended in February 2010, but later started again and finally ended in 2017.
