After asking a bunch of questions here, and reading the reviews, I took the plunge today and purchased Tier 4. Without a doubt this is one of my best purchases.

In all fairness, I ONLY needed it for UGC, Prompt Extractor, and Recreate video, so those are the only features I tried.

The UGC videos are VERY realistic and EXACTLY what I need in my AI application toolbox. The ai actors sound real, speak at a realistic cadence, and even have 'ring lights' in their eyes. For this alone, Yapper was more than worth the price of admission for me. I was concerned about how much it would realistically cost to generate what I need and the credit rate was more than reasonable. My only wish would be 'consistent character', but I'll keep my fingers crossed that it's coming, at some point. In the meantime, I LOVE what I can use this for.

Prompt extractor: Works like a charm! I used it with a 'starting frame' for my personal avatar and the resulting video was pretty darn good. I even liked it more than what I get from Higgsfield.

Recreate this video: Also works great. The prompts are good out of the gate and when you use the prompt enhancer, it's even better. Super impressive.

The models are even really good with letters and words.

I had a slight 'issue' with the UGC videos generating graphics (that I didn't want) and the Yapper support staff was super responsive - and today is Saturday! They resolved the issue quickly and to my satisfaction.

I'll probably never try: Deepfake, image or video generation (I use Higgsfield and HeyGen) but Yapper is light years better than Higgsfield, JoggAI, and HeyGen for UGC.

As for previous reviewers complaining about the lack of documentation? Maybe because I'm familiar with other applications, I didn't have any issues but there was never a point where I was unclear how to do what I needed to do. Zero frustration, and zero need to read the support documentation.

Lately, I haven't been too impressed with much in the AI space. Yapper is a breath of fresh air for me. 10 Tacos with extra guacamole and salsa with a round of spicy margaritas!
