innovative approach

Speecht-to-text/Machine translation


We re-imagined the creation of subtitles using the latest technology. No more wasted hours transcribing and synchronizing each sentence by hand. Our platform generates an automatic script of that singing accent that gives rhythm to your videos and then translates it into more than 140 languages.
