NotebookLM adds covers, custom summaries

NotebookLM now lets users add custom cover art and manually set notebook descriptions, giving shared research notebooks a cleaner presentation layer. The update is rolling out after users had been asking for more control over how notebooks look and explain themselves.

// ANALYSIS

This is not a core AI breakthrough, but it matters because NotebookLM is becoming less of a private research scratchpad and more of a shareable knowledge artifact.

–Custom cover art helps published notebooks feel curated instead of auto-generated
–Manual summaries fix a real UX problem: auto-refreshed descriptions can be unstable or poorly framed for collaborators
–The update fits Google’s broader push to make NotebookLM useful for creators, educators, and teams distributing source-grounded AI notebooks
–For AI developers, the signal is that UX and packaging around RAG-style tools are becoming product differentiators, not afterthoughts
