What is the best NotebookLM alternative for YouTube?

It depends on the size and life of the collection. For one project with a few dozen videos, NotebookLM itself is hard to beat. For a library that keeps growing across channels and podcasts, use a tool that saves transcripts without a per-notebook cap: Recall if you want to chat inside one app, BrainTube if you want Claude, Cursor and other MCP clients to search the same library.

How many YouTube videos can NotebookLM hold?

Each video counts as one source. Third-party guides checked in October 2026 report 50 sources per notebook on the free plan and more on Google's paid AI plans (around 100 on Plus and 300 on Pro). Check Google's current plan table before you rely on these figures.

Is NotebookLM the same as Gemini Notebook?

Yes. Google renamed NotebookLM to Gemini Notebook in July 2026; the old notebooklm.google address still works.

Can I add a whole YouTube channel or playlist to NotebookLM?

Not natively: you add videos one link at a time, and each counts toward the notebook's source cap. Browser extensions exist that batch links in. BrainTube follows a channel so new uploads arrive on their own, and imports a playlist in batches of 10 videos on Free, 50 on Starter and 150 on Pro.

Which alternative works with Claude?

Tools with an MCP server. Recall's MCP server is read-only (as of 4 October 2026); Glasp's can save bookmarks; BrainTube's is read-write on every plan, so Claude can search your saved videos and also save into the library.

NotebookLM alternatives for YouTube

The main NotebookLM alternatives for YouTube are Recall, Readwise Reader, Glasp and BrainTube, plus YouTube's own Ask button for a single video. NotebookLM stays the right pick for one project with a fixed set of videos; when your YouTube library keeps growing, its 50-sources-per-notebook free cap and one-link-at-a-time workflow start to bite.

The short answer

Keep NotebookLM (now Gemini Notebook) for one project with a few dozen videos. For a YouTube library that keeps growing, pick a tool that saves every transcript without a per-notebook cap: Recall to chat with it inside one app, Readwise Reader if you read and highlight more than you watch, and BrainTube if you want Claude, Cursor and other MCP clients to search the same library and save into it. For a quick question about the video in front of you, YouTube’s own Ask button is enough.

Tool	Good for	YouTube capture	Limit to know	Other AIs can search it
NotebookLM / Gemini Notebook	one project, fixed sources	paste links; one video = one source	free notebooks cap at 50 sources (Google help center, 1 Nov 2026)	No official way
YouTube's Ask button	a question about the video you're watching	built into YouTube	one video at a time, nothing saved	No
Recall	chatting with a growing library in one app	YouTube, podcasts, articles, PDFs	Free: 10 AI summaries a month, no chat	MCP, read-only (4 Oct 2026)
Readwise Reader	reading and highlighting, video included	YouTube with transcript	no free plan (30-day trial)	MCP, read-write
Glasp	highlights and quick summaries	YouTube summaries in the extension	highlights public by default on Free	MCP; only write is save_bookmark
BrainTube	a library that keeps growing, queried from any AI	videos, playlists, Liked videos, followed channels, podcasts	only knows what you save; web app, Chrome extension, iPhone and Android apps	MCP, read-write on every plan

Where NotebookLM fits, and where it stops

NotebookLM is organised around notebooks: you add sources, ask questions and get answers with citations back into those sources. For a thesis chapter or a course module that is exactly right. Three things change when YouTube is your main source:

Every video is a source. A free notebook holds about 50, so a long course or a creator’s back catalogue needs several notebooks or a paid plan.
Nothing arrives on its own. You paste links; a new upload from a channel you follow is not added for you.
Answers stay in the notebook. Each notebook is its own world, and the assistant you use the rest of the day (Claude, Cursor) can’t search it.

1. YouTube’s Ask button

For one question about the video you are watching, YouTube’s built-in Ask feature answers from that video. Nothing is saved, and it can’t compare across videos. Free and immediate; not a library.

2. Recall

Recall saves YouTube videos, podcasts, articles and PDFs, summarises them and lets you chat with the library in its app, with native iOS and Android apps and extensions for every major browser. Its free plan has unlimited saves and 10 AI summaries a month, without chat; Plus is $10 a month billed yearly. Its MCP server is read-only as of 4 October 2026, with write access announced. Compare in detail: BrainTube vs Recall.

3. Readwise Reader

Reader is a read-later app that also takes YouTube videos with their transcripts, so you can highlight a line in a talk the way you would in an article. It has an official read-write MCP server. No free plan, a 30-day trial, then $9.99 a month billed yearly. Best if highlighting is how you learn. See BrainTube vs Readwise.

4. Glasp

Glasp’s extension summarises YouTube videos and collects your web highlights, and its MCP connector (9 tools on the free plan) lets an AI read them; the only write is saving a bookmark. Highlights are public by default on Free. See BrainTube vs Glasp.

5. BrainTube

BrainTube keeps the transcript of every YouTube video and podcast you save, follows channels and feeds so new uploads arrive on their own, and imports your playlists and Liked videos when you connect YouTube. There is no per-notebook cap: saving a video or podcast one at a time is free on every plan, and its captions come with it (AI transcripts for videos without captions use credits). Search matches meaning and keywords across the whole library, answers in BrainTube’s chat link to the timestamp of the quote, and Claude, ChatGPT, Cursor and other MCP clients can search the same library and save into it.

Honest limits: it only knows what you save (it can’t read your watch history or Watch Later), AI extras such as generated podcasts and quizzes cost credits, and it runs as a web app, a Chrome extension, and iPhone and Android apps. Free costs $0 with 30 credits a month; Starter is $9 a month and Pro $19. Head to head: BrainTube vs NotebookLM.
