Subscription status

Temporary note about extension activation

Account sign-in is currently used for the NotebookLM Workspace extension. Other export extensions, including ChatGPT, Claude, Gemini, Grok, and Perplexity exporters for Notion, Obsidian, PDF, and related formats, still use email-based subscription activation while login-based verification is being migrated.

To activate those extensions, enter the email used for purchase inside the extension. The ChatGPT to Notion activation guide shows the same email-based flow as a reference.
