What Our Happy Users Say

Awesome App to Edit Videos

It is so fast and easy to create captions and subtitles for our marketing videos at Snappmeal. Also, it is convenient for us to translate our videos from Finnish to English (and vice versa) and add voice overs for our videos. We don’t have to spend so much time in finding the professional voice overs anymore.

We have a great tool!

Awesome! The tool has saved us so much time in creating voiceovers in Spanish and French for our videos. The customer support is fast and so friendly. Love the team!

"I love this product. I used other similar software before but they didn't work so accurately with the translation. For Hei, I can see that the translation and voiceover work better. We use mainly for our social videos and product tutorials for our videos and client projects."
