NotebookLM takes sources one at a time, through a file picker. Source LM takes the batch.
Point it at a JSON or Telegram HTML export, a YouTube playlist or a list of links, and the sources land in the notebook you already have open. Nothing is downloaded to disk: files are built in memory and sent through the notebook page's own upload path.
WHAT YOU CAN ADD - JSON datasets: preview how the file will be split into Markdown packed to the notebook's word limit, then upload. Records are never cut in half, and re-running the same file adds only what is new. - Telegram chat exports: the messages.html files from "Export chat history", split the same way. - YouTube videos, playlists and channels, from the popup or from an "Add to notebook" button inside YouTube itself. The top comment threads can ride along as a separate source. - Web pages: one link or a whole list, one per line. Pages a server cannot fetch (logged-in or JavaScript-rendered) are read from the tab you have open. - Selected text: right-click, "Add selection to Notebook".
IN THE SOURCES PANEL Filter by name, select duplicates in one click, delete everything checked in one batch, and replace sources NotebookLM failed to fetch with the text of the open page.
PRIVACY No server behind the extension and no account to create. Files, pages and notebook contents never leave the browser: it acts inside your own signed-in tab. Only your settings and pending jobs are stored, locally.
FREE AND PRO Single sources are always free. Bulk actions are free for 5 runs a month, then need a one-time $29 licence, no subscription. Chrome and Edge. Source-available under a noncommercial licence (not OSI open source): github.com/source-lm/source-lm-extension

Source LM EvernoteSource LM's answer
It builds the source files in memory and pushes them through the notebook page's own upload path, so nothing is written to disk and there is no backend and no account. A JSON or Telegram export becomes as many Markdown sources as it takes, packed to a 400,000-word budget under NotebookLM's 500,000-word cap per source, and a record is never cut in half. Run it again on a grown export and only the new records upload, because the state is read back from the notebook's own source names rather than from a local watermark.
Source LM's answer
Two practical differences. First, there is no server in the path: the extension acts inside your own signed-in tab, so your files, pages and notebook contents never reach a third party, and the code ships unminified and source-available so you can check that. Second, the price is a one-time $29 licence instead of a subscription, and single sources - one page, one link, one video, one selection - stay free forever; only bulk actions are metered, at 5 free runs a month.
Source LM's answer
People who already work in NotebookLM and have hit its one-at-a-time file picker: researchers and students loading a corpus of papers or transcripts, support and ops teams dumping ticket or chat exports, and anyone who wants a Telegram history, a YouTube playlist or a channel inside a notebook. No technical setup is assumed - it is a Chrome and Edge extension, not a script to run.
Source LM's answer
It started with a chat export that nobody wanted to split by hand: thousands of messages that NotebookLM would only take as files under its per-source word cap. The first version was a script producing Markdown chunks, and the annoying part was that the chunks still had to be dragged into the notebook one by one. Once the upload could go straight into the open notebook, the disk step disappeared, and everything else - YouTube, link lists, the current page, selected text - was routed through the same path.
Source LM's answer
TypeScript on Chrome's Manifest V3, bundled with esbuild, with zero runtime dependencies and no framework: the popup is plain DOM. There is no backend - uploads go through the notebook page's own upload endpoint from inside your tab, with a DOM-injection fallback if that path changes, and settings and pending jobs live in chrome.storage. Licence keys are checked directly against the payment provider's public API, so there is still no server of ours in the path.
The app helps keep everything organized and is really easy to use. I’ve been using it for a while now, and I really like it.
If you're someone who likes to keep everything in order and easily accessible, you'll want to check out the Evernote app. This app is designed to help you keep track of all your notes, ideas, and to-do lists in one place, and it does so with style.
From my experience using the app, I found that it's incredibly user-friendly and has a sleek design. You can easily create notes, organize them into notebooks, and even add tags to make it easier to find what you're looking for later on. Whether you're a student trying to keep track of your class notes or a busy professional juggling multiple projects, Evernote has you covered.
The thing that I personally like about Evernote is that before I have used word as my note taking application, than on my smartphone I have had used Google Keep and so my notes were just unorganized mess. But with Evernote now I can have my notes at one place and unified. Also the fact that I can log to another device and my notes are "just there" is really nice. And also I like graphics user interface of Evernote.

Obsidian is a multi-platform note-taking and writing app. Simple enough. But aren't there plenty of those around? Yes absolutely, but they each have downsides that I wasn't able to settle with long-term. With Google Cloud it was the difficult of linking between notes (this has improved since but it's still not quite what I want). With Evernote my notes were in a proprietary format and stuck in the cloud. Notion... - Source: dev.to / over 1 year ago
