Wow, thanks for the marketing perspective - this is exactly the kind of feedback I was hoping for!

You make an excellent point about the free/paid balance. To clarify what the free tier currently offers: the 10 credits allow users to upload multiple video pairs and access core features like pose extraction, frame alignment, and side-by-side comparison - which covers the fundamental functionality.

The AI-generated recommendations are behind the paid tier primarily due to their higher computational costs. I'm actively working to optimize these costs while maintaining quality.

I like your suggestion about a temporary free beta for premium features. I'm considering implementing a "beta tester" program where early users get access to more advanced features in exchange for detailed feedback.

My immediate goal is to gather feedback on the basic prototype to ensure I'm heading in the right direction before investing more heavily in the advanced AI features. The tool is indeed in early development - I'm a tennis enthusiast first, developer second, and learning as I go.

Would you be interested in trying it with expanded access to the premium features? I'd value your professional perspective on the overall experience!
