Subscriber is a solid scripting solution focused on YouTube, but you can re-purpose the scripts and research for other purposes. I ran into a few glitches during the scripting process, but they did not detract from producing a good script in any significant manner. I had previously been using Maekersuite - a previous Appsumo deal - and Subscribr is head and shoulders above that app. I originally bought in at Tier 3 and upgraded to Tier 4, which should work for my needs. The one thing I got confused on was the number of words allowed for added research documents during the scripting process. The limit is 5000 words, which is generally less than one reasonable-length YouTube video, so that feature is not useful in any meaningful way. Still, Subscribr gets a strong recommendation and from it's solid start is only bound to get better. Don't let this deal get away!
