What our analysis found

NotebookLM Tools for Gemini Notebook™, used by 100,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can inject scripts into pages. It comes from a trusted publisher and was last updated in October 2026.

Analyst notes

The extension is a legitimate power-tool for Google NotebookLM, as described. It requires broad permissions and host access to interact with NotebookLM pages and fetch user-selected web content, but all data flows stay within first-party domains ([domain withheld] for API calls, [domain withheld] for license management) and are consistent with the disclosed 'website content' collection. The ML model’s low risk score (0.00) already suggests a weak signal, and the permhash cluster contains no known malware. The auth token extraction is necessary for impersonating the user to perform NotebookLM operations, and no unauthorized data exfiltration was found.
