Set up
1
Install the extension
Install the browser extension and sign in to your MemoryPlugin account.
2
Open a notebook
Go to notebooklm.google.com and open a notebook. A floating MemoryPlugin button appears on the page.
3
Activate for the chat
Click the button to inject memories from your selected bucket into the query box, then ask your question. This also tells the model how to save new memories as you go.
The MemoryPlugin floating button on notebooklm.google.com. Click it to inject memories or open the panel.
What works here
- Memory recall and save. Memories are injected into the query box alongside your sources. NotebookLM still answers from the documents you added to the notebook, but your prompts arrive pre-loaded with the personal context it would otherwise miss.
- Extract memory pill. Select text in a chat and click Extract memory to save that snippet.
Limitations
- No chat history sync here. The extension captures new conversations only on ChatGPT, Claude, Gemini, Grok, DeepSeek, and TypingMind. You can still recall chat history imported from those tools while working in NotebookLM.
