Timesaver

Very nice piece of software. Automatic transcription works pretty well. In the end, you need just a little bit of post editing and you are ready to go.

Our startup has loved this product...

Our startup realized the potential of adding sub-titles to the digital content we present at our online events in order to boost our audience. Needless to say, we wanted a solution that could be implemented fast and easy, and Checksub checked all those marks. Within less than a week, the subtitling options were on. That's thanks to the diligence and customer support of Checksub.
