NotebookLM 是「源锚定」的研究工作台：你给一组源，它只在这些源里回答+生成音频概览/学习指南；它不是搜索引擎——是资料集上的问答引擎。

A source-anchored research workbench: you hand it a set of sources and it answers only inside them, plus audio overviews and study guides — it is not a search engine but a Q&A engine over your material.

适合与不适合When to use it, when not to

适合：给定资料集内问答（论文组/尽调/课程）、长材料转音频、源引用可追溯。不适合：开放网络检索、大陆直连（000）。

Q&A and research organization inside a given source set (paper groups, diligence packs, course material), turning long material into audio overviews, "answers only from your sources" scenarios. Not for: open-web retrieval (it does no web search — the sources are yours), mainland direct access (measured 000).

出品属地Origin: 国外出品foreign-made　Google（美国）。Google (US).
国内使用Direct access: 直连不可达direct blocked　notebooklm.google.com 大陆直连实测 000（2026-10-22，代理下 200 可达）——直连不可达，需网络环境。notebooklm.google.com measured 000 direct from mainland (2026-10-22; 200 via proxy) —unreachable without a network path.
备案状态CAC filing: 未见于备案名单not in filing list：未见于网信办公示名单（2026-10-22 检索）；该产品未面向大陆公众提供服务，备案不适用。not in the CAC public registry (searched 2026-10-22); the product does not serve the mainland public, so filing does not apply.

备案信息以网信办《生成式人工智能服务已备案信息》公示名单为准（按批次滚动更新，本站只抄编号不解读）；「大陆可直连」是本站从大陆网络直连实测的结果，不是厂商承诺。GitHub 类站点当日实测有波动，口径写在依据里。Filing status is quoted from the CAC public registry (updated batch by batch; this site copies the number and does not interpret it). "Direct access" is this site's own reachability measurement from a mainland network, not a vendor promise. GitHub-hosted sites fluctuated on the measurement day — the note says so.

固定坐标系Fixed coordinate system

8 个维度dimensions, 与同分区其他对象逐项可比each comparable item by item against others in the same section.

模型与开放条件Model & openness: Gemini 系模型驱动（官方叙事）；用户不选模型——产品形态是「源锚定问答」，模型是内部实现。
Driven by Gemini-family models (official narrative); users do not pick models — the product form is "source-anchored Q&A", the model is an internal implementation detail.
运行位置Where it runs: 网页（notebooklm.google.com）+ 移动 App；处理在 Google 云端。
Web (notebooklm.google.com) + mobile App; processing on Google's cloud.
本地文件Local files: 笔记本与源存账户侧云端；源可上传（PDF/Docs/网页链接/YouTube 等，官方产品面）。
Notebooks and sources stored on the account-side cloud; sources can be uploaded (PDF/Docs/web links/YouTube etc., official product surface).
关机后的任务Tasks after shutdown: 问答即时；Audio Overview（播客式音频概览）是生成任务线；无「关机续跑」概念。
Q&A is instant; Audio Overview (podcast-style audio overview) is a generation task line; no "keep-running-after-shutdown" concept.
工具与扩展Tools & extensions: 源锚定是产品主轴：回答带源引用、可追问；Studio 线生成音频概览/简报/学习指南等衍生形态（官方产品面）；笔记本内源管理（添加/删除/摘要）。
Source anchoring is the product's main axis: answers carry source citations and support follow-ups; the Studio line generates derived forms such as audio overviews/briefs/study guides (official product surface); in-notebook source management (add/remove/summarize).
上下文与记忆Context & memory: 以笔记本（notebook）组织——每个笔记本是一组源+对话；跨笔记本记忆未核验到官方声明。
Organized by notebook — each notebook is a set of sources + conversation; cross-notebook memory not verified to an official statement.
权限与限制Permissions & limits: Google 账号体系；免费档与订阅档的笔记本数/源量上限差异按官方页（未逐条核验，D9：价格不采）；训练用途：官方 FAQ 有「不用你的源训练」类承诺——引用前核 FAQ 原文（未逐条核验）。
Google account system; the notebook/source-count limits differing between free and subscription tiers per the official page (not verified item by item, D9: pricing not collected); training use: the official FAQ carries a "your sources are not used for training"-type promise — check the FAQ original before quoting (not verified item by item).
适合什么任务Best for: 适合：给定资料集内的问答与研究整理（论文组/尽调材料/课程资料）、把长材料转成音频概览、要「答案只从你的源里出」的场景。不适合：开放网络检索（它不做全网搜索——源是你给的）、大陆直连（实测 000）。
Fits: Q&A and research organization inside a given material set (paper groups/due-diligence materials/course materials), turning long materials into audio overviews, scenarios wanting "answers only from your sources". Does not fit: open-web retrieval (it does no whole-web search — the sources are what you give it), mainland direct connection (measured 000).

头号误解Top misconception

NotebookLM 不是搜索引擎——它只在你给的源里回答；「查全网」要用 Perplexity 类产品NotebookLM is not a search engine — it answers only inside the sources you give; for "search the whole web" use a Perplexity-class product
Audio Overview 的生成质量随源质量波动——垃圾进垃圾出在源锚定产品里同样成立Audio Overview quality tracks source quality — garbage in, garbage out holds just as hard in a source-anchored product
「不用源做训练」是官方 FAQ 承诺——企业敏感材料仍要按条款与 Workspace 合规面核（未逐条核验）"Your sources are not used for training" is an official FAQ promise — for sensitive enterprise material still check the terms and the Workspace compliance surface (not verified line by line)

实测记录Measured runs

本档未跑检索质量评测；结论只覆盖产品能力与来源披露。

实测建议（三条，都指向官方可读页没给的东西）：

长 PDF（500+ 页）的源覆盖完整度（会不会静默截断）
Audio Overview 对中文源的支持质量
免费档笔记本/源上限的实际值（D9：价格不采；额度实测）

This site has not completed measured runs. The coding-oriented test protocol is at protocols/coding/_protocol.md (the coding task suite does not apply to creation products).

Suggested measurements (three, all pointing at things the official readable pages do not give):

Source coverage completeness for long PDFs (500+ pages) (whether it silently truncates)
Audio Overview's support quality for Chinese sources
Actual values of the free tier's notebook/source limits (D9: pricing not collected; quotas measured)
