Hello Tiny Talk Team,

I'm considering purchasing AppSumo Tier 6.

Could you please confirm:

1. Is BYOK (Bring Your Own OpenAI API Key) mandatory for Tier 6?
2. Does Tier 6 include any free AI credits or AI responses without my own API key?
3. Are there any additional monthly AI model charges?
4. Can I use the chatbot across Shopify, Grigora and Brizy Cloud websites?

Thank you.
