Quick answer
Facts below come from each tool's own site or store listing, checked October 9, 2026. We make GetYouTubeTranscript, so it is marked and described by the same criteria as the rest. Where a price or limit is not published, we say so.
| Tool | Best for | Pricing | Main limit |
|---|---|---|---|
| NotebookLM native YouTube source | Best for a single video | Included with NotebookLM. Sources per notebook: 50 on the free plan, 100 on Plus, 300 on Pro (Google marks these limits "subject to change"). | Needs captions (uploaded or auto-generated), no videos under about 72 hours old, and each source is capped at 500,000 words. Google documents no playlist or channel import. |
| YouTube to NotebookLM (Chrome extension) | Most popular bulk importer | Not published on its Chrome Web Store listing. | No limits are stated on the listing, so check the extension itself before relying on it for large channels. |
| YouTube to NotebookLM (youtube-to-notebooklm.com) | Best for occasional bulk imports | Free: 5 imports per month. Paid: $4.99/month, $19.99/year, or $29.99 once (lifetime). | Channel import covers recent uploads with no stated depth, and the site does not say what counts as one "import", so the free cap is hard to size for a big playlist. |
| NotebookLM Web Importer | Best for mixing web pages and videos | Free tier: 20 single-page imports per day. Premium: $1.50/month or $19/year (the site also lists a lifetime option), with a 7-day money-back guarantee. | Bulk import from a YouTube playlist is a Premium feature. Channel import is not mentioned anywhere on the site. |
| Add to NotebookLM: YouTube & Web Importer | Best free option | Free. | Needs a Google account signed in to NotebookLM. The "Add as PDF" feature uses Chrome's debugger API, so Chrome shows a debugging notice. |

Pro and ULTRA tiers exist but no prices are published on the listing. | Up to 100 sources per batch. Auto-sync and AI features need a paid tier. Small rating base (4.3 stars from 3 ratings). |
| GetYouTubeTranscript (web tools)our tool | Best for one clean combined text file | The web tools are free with no sign-in, 10 videos per batch. A batch API for whole channels is on paid API plans. | Extra manual step (download, then add as a source), public videos only, and 10 videos per batch on the free tools. |
| BulkTranscripts | Best for very large playlists | One-time credit packs, no subscription: 30 free credits, then $4.99 for 200 up to $499 for 200,000. Credits do not expire. | Only videos with an accessible caption track work (others are skipped and reported, not charged). Public content only. |
| Copy and paste the transcript | Fallback when the native import fails | Free. | One video at a time by hand. A pasted source still counts toward the notebook source limit and the 500,000-word cap, and a video with no captions has no transcript to copy. |

Fallback when the native import fails
Open the transcript panel under a video, copy the text, and paste it into NotebookLM as a copied-text source. Works when the native YouTube source rejects a video.
Pricing: Free.
Limitation: One video at a time by hand. A pasted source still counts toward the notebook source limit and the 500,000-word cap, and a video with no captions has no transcript to copy.
Visit Copy and paste the transcriptWhich should you choose?
For one video, use NotebookLM's built-in YouTube source. For a whole playlist or channel, use a Chrome extension that sends videos to NotebookLM in bulk: "YouTube to NotebookLM" (about 500K users) and "Add to NotebookLM" (free, no limits stated) are the two most direct. If you want one clean combined text file instead of a sync, extract the transcripts first and add the file as a single source. The table above has each tool's price and its main limit; the sections give the detail.

Can NotebookLM import a whole YouTube playlist?
Google's help pages document adding public YouTube video URLs one source at a time and do not describe playlist or channel import. To add many videos at once, use a bulk importer extension or extract the transcripts first and add them as a file.
How many sources can a NotebookLM notebook hold?
Per Google's help page, 50 on the free plan, 100 on Plus, 300 on Pro, and 500 to 600 on the Ultra plans. Google marks these as subject to change, and Workspace editions use a different table.
Why does NotebookLM reject some YouTube videos?
Google lists the common causes: the video has no captions, speech is not detected, the language is unsupported, the video is private or under about 72 hours old, or the link is invalid.
Is it better to import videos one by one or as one combined file?
Separate sources let NotebookLM cite each video by name, but each counts toward the per-notebook source limit. A combined file uses one source slot, which helps with large playlists, at the cost of coarser citations.
