Isn't NotebookLM already exactly web and file context (a "ContextChat")?

Edit: I assume it is basically a similar product, but your differentiators are mainly the customer getting to choose their model, and you getting to write your own context adding ergonomics (like adding links from a Sitemap)?

Exactly, similar plus tools to import and manage projects context fast (like GitHub private repos and sitemaps url), multiple ai model and pay per use like using APIs
