🇹🇼 NotebookLM 深度實測：Google 的 AI 筆記本到底多強？
Google 的 NotebookLM 可能是 2025-2026 年最被低估的 AI 產品。它不像 ChatGPT 那樣到處被討論，但在特定場景下，它的表現讓我非常驚豔。以下是我使用半年多的深度心得。
NotebookLM 是什麼？
簡單來說，NotebookLM 是一個以你的資料為基礎的 AI 助手。你上傳文件（PDF、Google Docs、網頁、YouTube 影片等），它會基於這些資料回答問題、生成摘要、找出關聯。跟 ChatGPT 最大的差別是：它只根據你提供的資料回答，大幅減少幻覺。
最強功能：Audio Overview（播客生成）
NotebookLM 最令人驚豔的功能是自動生成播客風格的音頻摘要。上傳幾份報告，它能產出一段兩個 AI 主持人對談的音頻，討論你文件中的重點。這個功能對於：
- 通勤時學習：把長報告變成可以聽的播客
- 快速理解複雜文件：用聽的比用讀的更容易抓重點
- 團隊知識分享：把會議記錄或研究報告轉成音頻分享給團隊
研究與學習場景實測
我用 NotebookLM 做過以下測試：
- 學術論文分析：上傳 10 篇相關論文，讓它找出共同發現和矛盾之處——效果非常好
- 法律文件審閱：上傳合約，問它特定條款的意涵和風險——回答精準且有引用
- 技術文件理解：上傳 API 文件，用對話方式快速理解用法——比直接讀文件快三倍
- 書籍摘要：上傳整本書的 PDF，生成章節摘要和關鍵洞察——非常實用
優點
- 資料基礎回答：每個回答都有引用標註，點擊就能跳到原文
- 完全免費：目前不收費（Google 的策略可能是吸引用戶進入 Google 生態系）
- 多語言支援：中文、英文、日文都沒問題
- 隱私：Google 聲明不會用你上傳的資料訓練模型
缺點與限制
- 來源數量限制：每個 notebook 最多 50 個來源
- 沒有即時網路搜尋：只能根據已上傳的資料回答
- PDF 表格處理：複雜的表格和圖表有時會解析失敗
- 無法自訂 Audio Overview 的內容：你不能指定播客討論的重點（不過 Google 持續在改善）
結論：特定場景的最佳工具
NotebookLM 不是要取代 ChatGPT 或 Claude，它的定位是文件理解和知識管理。如果你的工作涉及大量閱讀和資料分析，NotebookLM 值得納入你的工具箱。好不好用，試了才知道。
🇺🇸 NotebookLM Deep Review: How Powerful Is Google's AI Notebook?
Google's NotebookLM might be the most underrated AI product of 2025-2026. It doesn't get the buzz that ChatGPT does, but in certain scenarios, its performance genuinely impressed me. Here is my in-depth review after over six months of use.
What Is NotebookLM?
In simple terms, NotebookLM is an AI assistant grounded in your own data. You upload documents (PDFs, Google Docs, web pages, YouTube videos, etc.), and it answers questions, generates summaries, and finds connections based on those sources. The key difference from ChatGPT: it only answers based on the data you provide, dramatically reducing hallucinations.
Killer Feature: Audio Overview (Podcast Generation)
NotebookLM's most impressive feature is automatically generating podcast-style audio summaries. Upload a few reports and it produces an audio conversation between two AI hosts discussing the key points from your documents. This is great for:
- Learning during commutes: Turn lengthy reports into listenable podcasts
- Quickly grasping complex documents: Listening can be more effective than reading for catching key points
- Team knowledge sharing: Convert meeting notes or research into audio for the team
Real-World Testing: Research and Learning
I tested NotebookLM across several scenarios:
- Academic paper analysis: Uploaded 10 related papers and asked it to identify common findings and contradictions — excellent results
- Legal document review: Uploaded contracts and asked about specific clause implications and risks — precise answers with citations
- Technical documentation: Uploaded API docs and used conversational queries to understand usage — three times faster than reading directly
- Book summaries: Uploaded entire book PDFs for chapter summaries and key insights — extremely useful
Strengths
- Source-grounded answers: Every response includes citation markers you can click to jump to the original text
- Completely free: Currently no charge (Google's strategy likely aims to draw users into the Google ecosystem)
- Multilingual support: Works well with Chinese, English, Japanese, and more
- Privacy: Google states uploaded data is not used for model training
Weaknesses and Limitations
- Source limit: Maximum 50 sources per notebook
- No real-time web search: Can only answer based on uploaded materials
- PDF table processing: Complex tables and charts sometimes fail to parse correctly
- Cannot customize Audio Overview focus: You cannot direct what the podcast discusses (though Google is continuously improving this)
Conclusion: The Best Tool for Specific Scenarios
NotebookLM is not trying to replace ChatGPT or Claude. Its niche is document understanding and knowledge management. If your work involves heavy reading and data analysis, NotebookLM deserves a place in your toolkit. You won't know until you try.
