On Kortex-Notebooklm
Kortex turns Google’s NotebookLM from a chat-first scratchpad into a permanent, searchable knowledge hub. It adds one-click exports (PDF, Markdown, Text, ZIP), bulk imports from web, social, and Google Docs, and a full dashboard for organizing notebooks, sources, tags, and automations. Highlight text anywhere and send it straight to a notebook, or build reusable prompt libraries. Cloud sync, podcast feeds from notebooks, and 80+ other features are available on paid tiers; the free plan caps exports and imports but still lets you highlight and search.
Kortex is the missing power-up for NotebookLM users who want their knowledge to stick around. It solves the core pain of fleeting chats and siloed notebooks by turning them into a permanent, searchable second brain with real exports, bulk imports, and automations. If you rely on NotebookLM daily and hate redoing work, the Pro tier is a no-brainer; the Lifetime Pro is an even better deal if you plan to use it for years.
