Gemini Notebook Second Brain Setup Planner
Answer five quick questions and get a complete second-brain blueprint for Gemini Notebook (formerly NotebookLM): which notebooks to create, how to organize collections and tags, and rules for routing every captured source to the right place.
Frequently Asked Questions
How do I set up a second brain in NotebookLM?
Start with a small set of notebooks tied to what you actually work on — one per project or theme — plus a dedicated Inbox where every new source lands first. Tag each source with a status and topic on capture, then triage the Inbox weekly. This planner generates that whole structure for your role in Gemini Notebook (formerly NotebookLM), so you are not starting from a blank page.
How many notebooks should I have?
Fewer than you think. Aim for three to five active notebooks that map to real projects or themes, plus one Inbox for capture. More notebooks means more places to look and more filing overhead. When a project finishes, archive its notebook rather than letting it clutter your active workspace.
How do I keep sources organized automatically?
Gemini Notebook Toolkit adds Smart Collections that group new captures by rule, and a Domain Router (a Pro feature) that auto-routes each captured source into the right workspace based on rules you set — so an AI chat, a PDF, or a web clipping files itself. Universal library search is keyword-based, so consistent tags keep everything findable without manual sorting.
Automate the routing
Gemini Notebook Toolkit's Smart Collections and Domain Router send every captured source to the right workspace automatically, so your second brain stays organized without manual filing.
