I replaced NotebookLM with a local LLM, and the difference is night and day
The author switched from using Google's NotebookLM to a local large language model (LLM) for privacy reasons, particularly when handling sensitive personal data like medical records. While NotebookLM offers strong features like source grounding and citation, the concern over uploading private documents to cloud servers prompted the shift. Using a local LLM ensures data remains on-device, providing greater control despite requiring more technical setup. The author finds the trade-off worthwhile for sensitive tasks.
- ▪NotebookLM retains uploaded documents, chat history, and generated outputs as long as the notebook exists, even though it doesn't use them to train its models.
- ▪The author chose a local LLM to avoid sending personal health data to external servers, citing privacy concerns after watching content about data security.
- ▪Local LLMs process data entirely on the user's device, preventing any risk of cloud-based data exposure.
- ▪The author uses LM Studio with the Qwen 3.5 model to analyze documents locally, maintaining control over sensitive information.
- ▪While NotebookLM offers unique features like interactive mind maps and citations, local models provide superior privacy for personal or sensitive use cases.
