# NotebookLM: Maximum Productivity

> A detailed guide on our favorite tool from the Google ecosystem. How to collect quality sources, use Telegram for research, and get the best results.

## 1. Why NotebookLM and Tool Advantages

> [!TIP]
> **Why NotebookLM?**
> Statistics show that NotebookLM is often used more frequently than standard Gemini. There is a paradoxical but logical reason for this:
>
> - **Uses only your sources:** Unlike other models, it doesn't invent facts but relies solely on what you provide.
> - **Free and fast:** A convenient interface for quick learning and research.
> - **The better the source, the better the answer:** Success with NotebookLM depends 90% on the information you upload to it.

## 2. Interface and Adding First Sources

When you open NotebookLM and create a new notebook, the first thing you are offered is to add information sources.

**You can add data from:**

- Google Drive
- Local files from your computer
- Websites and links
- Copied text

Functions are available for both quick search and "deep research".

## 3. The Secret of Quality Sources: Telegram as a Knowledge Base

The most interesting practical example of working with NotebookLM is using a knowledge base from **Telegram chats and channels**. Much expert information is located exactly in closed channels or thematic chats.

> [!WARNING]
> **Important:** The regular Telegram from the App Store (Mac) is not suitable for effective data export! You will need a different version.

## 4. Installing the Right Telegram Desktop Version

There are two versions of Telegram Desktop. For our purposes, we need the client downloaded directly from the website.

> [!IMPORTANT]
> **Official Telegram Desktop Website**
> Download the blue version from the website: **telegramdesktop.org**

**Why this exact version?**

- **Lower price:** Premium subscription is usually cheaper here due to the absence of store commissions.
- **Clear downloads folder:** A `Telegram Downloads` folder is created. In the App Store version, files are saved in a hidden system folder that is impossible to find, and it is only cleared by resetting the cache.
- **Main advantage — Export:** Only this version allows exporting the history of channels, chats, personal correspondence, and closed communities.

## 5. Exporting History for Research

The process of collecting a knowledge base for your NotebookLM looks like this:

- 1. Use the search to find the necessary channels or chats on the desired topic.
- 2. Open this chat/channel on your computer.
- 3. Click on the magic **"three dots"** in the upper corner of the window.
- 4. Select the **"Export chat history"** option.
- 5. Wait for all data to be downloaded to your computer.

## 6. Working with Knowledge Base and Practical Queries

When you have downloaded the chat or channel history:

- Upload the obtained files to your NotebookLM notebook.
- The neural network will quickly analyze all the text, all advice and links discussed over the years.
- Now you can ask questions to your notebook and receive comprehensive answers based exclusively on expert data from the exported communities.
