FreeVerified · NotebookLM / Gemini Notebook·Markdown

Short answer

NotebookLM cannot open a ChatGPT conversation from its link. Either copy the conversation and paste it as a text source, or open the chat with NotebookLM Ultra Exporter installed and click the extension icon: quick capture extracts the loaded prompts and replies and adds them to the notebook you choose. It is free.

What to know

  • Scroll long conversations first so every message is loaded.
  • Claude, Gemini, DeepSeek, Kimi and Doubao chats are captured the same way.

Google changes these menus often. The item's own menu in your notebook shows what is built in today.
