By the far the most user friendly software to use.
As a housewife at home looking to start a Youtube channel for fun with absolutely zero editing experience, it was so easy for me to teach myself via their YouTube channel. It takes the tediousness out of editing and encourages creativity. As long as Kapwing is around, I will be using their software.

Love this site.
As a English Foreign Language Teacher, this site helps me to quickly subtitle interesting videos that I can use in class. The students love the videos, and the subtitles really help them to learn new vocabulary as well as better understand and follow the video.

Excellent subtitling features
[It] works perfectly for me. Have been using Kapwing for a year or so, and their automatic subtitle tool gets better and better every week, it's rare that I have to correct a word. Keep up the good work!
