Solves the difficulty of finding and applying professional, visually appealing infographic styles in NotebookLM by providing a browsable, searchable gallery of pre-designed style prompts and previews.

1. User navigates to notebooklm.google.com. 2. Extension injects a style gallery UI into the 'Customize Infographic' dialog. 3. User browses or searches for a style. 4. User clicks a style card, which automatically fills the style prompt into the textarea. 5. User generates the infographic with the applied style.

Target users: NotebookLM users who create infographics / Content creators, educators, and professionals looking for design inspiration

The extension only runs on notebooklm.google.com, so analysis is limited to that context. No external API calls were detected beyond Google's update server.

Monetization

No paid features detected

The extension provides a gallery of infographic styles for NotebookLM. All styles are bundled locally within the extension package (content.js and images/*.jpg). There is no code related to payments, subscriptions, billing, license keys, or premium feature gating. The keywords 'pro', 'auth', and 'trial' found in the static scan are false positives: 'auth' appears in style prompt text (e.g., 'authoritative'), and 'pro' appears in style names/descriptions (e.g., 'professional', 'pro-engineered'). The extension is entirely free to use.

Reason: The extension is a content script that runs exclusively on https://notebooklm.google.com/* (manifest.json). NotebookLM is a Google service that requires a Google account to access. The extension does not implement its own login system; it relies entirely on the user being logged into the destination service (NotebookLM) to function. The core workflow of browsing and applying infographic styles requires an active NotebookLM session.
