The intro says the product is “AI-native”, but I couldn’t find any details about this in the docs. What does it mean?

If you check our landing page, we have a section where we explain that a bit: https://modelence.com

One of the AI-native aspects is if you use the built-in AI SDK (https://github.com/modelence/modelence/tree/main/packages/ai), you get all your AI prompt runs in the built-in dashboard in Modelence Cloud and you can also connect your AI provider (e.g. OpenAI) in the dashboard without having to manually specify the key in the code or pass through environment variables.

But there's more we adding soon - vector search and embeddings that are built into your database / MongoDB documents.
