What is Lilys AI?
The official website of LilysAI describes itself as "your AI-native content distilling assistant", and its slogan is Meta's "Put a turbo engine on your brain". The homepage slogan "Just Save and Subscribe. Never miss insights." indicates that its interaction method is not opening an editor, but instead dropping materials into it like a bookmark folder.

The site footer states that it is made in Seoul and operated by LilysAI, INC., and the homepage demo area also bears the Y Combinator label.
