In one of his recent podcasts he explained that he wanted to create a mixture of Google Earth and a libray. So "Library" is specifically meant as a name for the mixed data source aggregation.
To be clear: The entire software is vibecoded in a language Pritlove doesn't even have worked with prior to that. But when it comes to talking about his ideas Pritlove surely does not need a LLM. This guy basically started the German podcast scene and has been talking about software for at least 30 years.
Germans are still LLM, just in human form.
I think that's the idea, yes. Usually the mediator is the publisher of the software who at least maintains a proxy, but often recombobulates the data in a way that makes for sense for their software. This is also doesn't leave the original publisher paying for the software user's traffic. Probably not much an issue for a first release.
