Udemy Dual Subtitles


Due to the Backend Service cost, including APIs' fees & Cloud Service fees, etc.
Udemy Dual Subtitles needs to charge a small monthly fee to cover the bill.
Actually, this monthly price is relatively small compared to what would cost if you use these Service yourself. And we've avoid many pitfalls for you.
