Independent developers of software products, mainly for students. With modern laptops, beside creating a Word file summary for the lecture, one can also record the lecture using the laptop's built-in microphone. Even though recording the lecture is fairly easy, not many students do this, for the obvious reason that working with voice files is not as comfortable as working with written summaries. Wanting to make voice recordings more accessible and easy-to-work-with, we've created Synx - an application used to record as you type, syncing the voice to the keyboard strokes. Later, when reading your summary, simply press a place in the document to hear what the lecturer was saying at that moment.
