What Is NotebookLM?NotebookLM 是什么？
NotebookLM (now Gemini Notebook) is Google's source-grounded research notebook. You create a notebook, add sources — PDFs, Word, text, Markdown, CSV, PowerPoint, Google Docs/Slides/Sheets, web URLs, public YouTube videos, audio files, images, ePub, pasted text — then chat with it. Its answers cite the exact passages they came from, so it's far less likely to invent an API or a fact than a general chatbot answering from memory — though it can still misread a source, so click the citations when it matters.NotebookLM（现名 Gemini Notebook）是 Google 的来源引用型研究笔记本。建一个笔记本、加来源——PDF、Word、文本、Markdown、CSV、PPT、Google Docs/Slides/Sheets、网页 URL、公开 YouTube 视频、音频、图片、ePub、粘贴文本——然后跟它对话。它的回答引用来源里的确切段落，比凭记忆回答的通用聊天机器人难编造得多——但仍可能读错来源，重要的事点引用进去看。
Free tier: 100 notebooks, 50 sources per notebook, no credit card — per-source caps of 500,000 words and 200MB on the free plan. Since September 2, 2026, usage limits are compute-based and refresh every five hours up to a weekly cap (replacing the old fixed daily counts like 50 chats/day). Google AI Pro ($19.99/month) raises the limits. Prices per the official site.免费档：100 个笔记本、每本 50 个来源，免绑卡——免费档单来源上限 50 万词/200MB。2026 年 9 月 2 日起用量限制改为按算力计、每 5 小时刷新至周上限（替代原来的固定每日次数，如每天 50 次对话）。Google AI Pro（$19.99/月）扩容。价格以官网为准。
From your sources it generates Audio Overviews (Deep Dive, Brief, Critique, Debate — 80+ languages), Video Overviews, editable and shareable flashcards and quizzes (adjustable topic and difficulty), study guides, briefing docs and Deep Research investigations — plus a Learning Guide chat mode that asks probing questions instead of handing over answers. On October 19, 2026 Google added a co-creation flow for Slide Decks: suggest topics from your sources → confirm style → review the outline → proceed to render (skippable if you want the old one-shot generation).基于你的来源，它能生成 Audio Overviews（Deep Dive/Brief/Critique/Debate，80+ 语言）、Video Overviews、可编辑可分享的 flashcards 与测验（主题难度可调）、学习指南、简报文档和 Deep Research 调查报告——还有 Learning Guide 对话模式，用追问代替直接给答案。2026 年 10 月 19 日 Google 新增 Slide Deck 审核流：按来源建议主题 → 确认风格 → 先审大纲 → 再生成（也可跳过，走原来的一次生成）。
Gemini Notebook is the anti-hallucination research tool: the citation-first design solves the one problem that makes generic chatbots unusable for serious work — you can always inspect the passage behind an answer. The rename (July 16, 2026) changed nothing about the product, which is why this page carries both names — people still search for NotebookLM. The October 19 slide-deck review flow fixes the real pain of AI decks (wrong structure discovered after generation), and the compute-based limits since September 2 are actually more generous for bursty research than the old fixed daily counts. The honest limits: it's only as good as your sources, it can still misread them, and NotebookLM's sharing model is notebooks and public links, not real workspace collaboration. Verdict: if your work starts with a defined body of evidence — docs, papers, briefs, course readings — start here free; upgrade only when source capacity or compute limits interrupt real work.
Gemini Notebook 是反幻觉研究工具：引用优先的设计解决的是通用聊天机器人做不了正经活的那个根本问题——每个答案背后都能点进去看原文。更名（2026 年 7 月 16 日）没改变产品任何东西，所以本页新旧名并用——大家还在搜 NotebookLM。10 月 19 日的幻灯片审核流修的是 AI 做 PPT 真正的痛（生成完才发现结构错了），9 月 2 日起的按算力计限额对爆发式研究其实比原来固定每日次数更慷慨。真实局限：它只和你的来源一样好，仍可能读错；分享就是笔记本和公开链接，不是真正的 workspace 协作。结论：如果你的工作起点是一批确定的证据材料——文档、论文、简报、课程读物——从这里免费开始；只有当来源容量或算力限额打断了真实工作，再升级。
