Our Verdict
Depends on your workflow
Pick Gemini Notebook Toolkit if you want capture from AI chats and the web into a searchable, exportable library, an MCP server for AI agents, and a cheaper lifetime license ($149 vs $200). Pick Kortex if you mostly need in-notebook power tools such as notebook merge, podcast RSS and scheduled automations, which Toolkit does not offer today.
