Q: How does it compare with BigVU ?
Big VU provides editing facility with background music, greenscreen, subtitles etc Can you please highlight the differences for me to choose between the 2 deals ?
Hello and thanks for the question, When it comes to efficient teleprompter accessibility I believe PromptSmart is your best choice, our patented VoiceTrack recognition software is going to make creating content much easier and effective. PromptSmart does feature duplicate display screens for multi-cameras set ups and in script editing in app, at this time we don't have background music and green screens but amazing new features are always in development to provide value to our PrompSmart customers.

See my comments above for some information from an actual user perspective.
The two are not an exact product, so a comparison doesn't really help much - and I say that as someone that owns both products.
Best to identify your own use cases i.e., what you intend to achieve and then see which one checks the most boxes.
But, if it's more of the teleprompter functionality, my recommendation is Promptsmart Pro.
