Enhancer 4 Google was developed to maximize the potential of the amazing services provided by Google. From quality-of-life UI improvements that address specific needs to advanced automation features not originally available, it is packed with functions for power users.
〇Turn NotebookLM into the "Ultimate Knowledge Base"
Make information organization and insight acquisition smoother and more powerful.
- Homepage Categories & Search: Organize your cluttered homepage. Group notebooks into custom categories with color coding to keep your workspace tidy. Plus, find any notebook instantly with the new real-time search bar.
- Web Crawler & Source Generator: Solves NotebookLM's biggest challenge: "importing website hierarchies." It automatically crawls pages by following links from a specified URL (root) and combines/outputs them as a single Markdown file optimized for NotebookLM. Converting an entire site into knowledge has never been easier.
- Sync Scheduler (Auto Sync): Previously, even if the source Google Drive or Web page was updated, you had to manually press the sync button on the NotebookLM side. With this feature, synchronization runs automatically in the background at specified intervals (hourly, daily, weekly, etc.). Your Notebook is always up to date whenever you open it.
- Bulk Sync Button: Even for notebooks holding a large number of sources, you can check for updates and sync all sources with a single click. There is no need to click through them one by one.
- Studio Panel Optimization: The "Studio" panel, which tends to occupy screen space, can now be collapsed to secure a wider chat area. It prevents unintended generation caused by accidental clicks on the "Audio/Video Overview" button and changes behavior to always open the edit prompt, preventing wasted credits.
〇Turn Gemini into a "Comfortable Writing Environment"
Make sessions with conversational AI more spacious and speedy.
- Content Width Expansion (Wide Mode): Break free from the standard narrow display width. You can freely adjust the maximum width of the chat area from 760px to 5000px to match your monitor. Code blocks and table data can also be viewed comfortably without wrapping.
- Expandable Markdown Editor: Say goodbye to writing complex prompts in tiny text boxes. This feature adds an 'Expand' button to input fields (especially useful for Gems custom instructions), opening a full-featured popup editor. It comes equipped with Markdown support (headings, tables, code blocks), live preview, and smart list handling (auto-numbering/indentation), making prompt engineering significantly more efficient.
- Gem Manager Search: No problem if your created Gems (Custom Bots) increase. A search bar has been added to the Gem list page, allowing you to instantly find the target Gem by name or description.
- Tool Shortcuts: Access buttons for frequently used tools like "Deep Research" and "Canvas" are permanently placed in the prompt input field. This saves the trouble of searching deep into menus.
〇"Automate Material Creation" with Google Slides
Reduce the effort of turning PDF materials into slides to zero.
- PDF to Slides Import: Adds a "Import PDF" button to the slide editing screen. Simply drag and drop your PDF file, and it converts all pages into images and automatically places them on each slide page in coordination with Google Apps Script (GAS).
- Image ZIP Bulk Download: It is also possible to download high-quality slide images converted from PDF as a ZIP file in bulk. This is useful for reusing materials. (Note: To use this feature, you need to set up GAS with your own Google account. A complete manual is provided.)
〇Google Chat & Common Features
Prevent operational errors and customize usage to your liking.
- Prevent Accidental Sending (Custom Key Binding): Customize how you send messages. Change the default behavior to "Enter for new line" and choose your preferred trigger for sending: Shift+Enter, Ctrl+Enter, or Alt+Enter. This prevents incomplete messages from being sent by mistake and applies to NotebookLM, Gemini, and Google Chat.
〇Privacy and Security
This extension is designed with "User Privacy Protection" as the top priority.
- Data Stays with You: All configuration information and task data are saved only within the browser (Chrome Storage). Nothing is ever sent to the developer's server.
- Transparent Communication: The destination for PDF data in the Google Slides function is only the URL of the Google Apps Script set by you. The Web Crawling function is also executed only for the URLs you specify. No data is sent to unintended third parties.
- Privacy Policy: https://enhancer.corp-4u.com/privacy.html
Disclaimer: This extension is provided "As Is". Please note that functions may become unavailable without notice due to specification changes in Google services, etc.
