Sooner or later, every AI notebook gets held up against NotebookLM. Ours too. It's a fair comparison to make, because Google built something very good. But we made a decision early on that Gistr would do a different job, and this post is about that decision: what we chose, what we left out, and when you'd honestly be better off with Google's tool.
Quick answer first. If you research across a pile of PDFs and Google Docs and like listening to AI recaps, use NotebookLM (now called Gemini Notebook). If you learn from YouTube lectures, podcasts and articles and want to still remember them a month later, that's the problem we built Gistr for.
The summary you can't remember
Here's a week most students and researchers will recognise. A 90-minute lecture on YouTube, a 40-page PDF from your professor, and a podcast someone in your study group swore by. You paste all of it into an AI tool and get back a tidy summary. It's accurate. It's well organised. Seven days later you couldn't explain a single idea from it to a friend.
The summary was fine. You just never did anything with the material. The AI did the reading and the condensing, so the understanding stayed with the AI too.
That pattern shaped almost every product call we've made. An AI that reads for you is useful when you need to find things. It's much less useful when you need to know things, the way you need to know them in an exam hall or in front of a class.
What NotebookLM gets right
A post like this can read as a dig, so to be clear: we like NotebookLM.
On July 16, 2026, Google renamed NotebookLM to Gemini Notebook. Google's FAQ calls it "the same product you know and love," your notebooks stay where they are, and old links redirect. Most people still search for "NotebookLM," so we use both names here.
The free tier is generous. Gemini Notebook Standard gives you 100 notebooks and 50 sources per notebook, and each source can be up to 500,000 words or 200 MB. That covers a semester of readings with room to spare.
Audio Overviews are still the thing people talk about, and for good reason. You hand it your sources and get back a podcast-style conversation about them. Google has since added Video Overviews, Mind Maps, Reports, Infographics and Slides, and its FAQ suggests flashcards and quizzes for exam prep.
It also fits into Google's world. You can import from Google Drive, and Docs or Slides you import stay in sync with the original file. Google says answers are "grounded in the information you provide," and you choose the sources.
If your job is to research across many documents and get answers you can trust, that's a very strong product. We'd rather not build a slightly different copy of it.
The job we picked instead
Gistr is built around one question: how do you learn something from a video, a podcast or a web page, and keep it?
That question led to a few choices that look odd if you're expecting a NotebookLM clone.
The video stays a video
Most AI tools treat a YouTube video as a block of text. Gemini Notebook's help page says that "only the text transcript of the video is imported as a source." For a talk where the speaker says everything out loud, that works. For a chemistry lecture where the professor points at a diagram, or a coding tutorial where the code is on screen, a lot of the lesson never makes it into the transcript.
So in Gistr the video plays inside your notebook. Click any transcript line or chapter and the player jumps there. Your notes carry timestamps, and you can clip a key moment into your notes and replay it later. Podcasts work the same way: you listen inside Gistr, read the transcript as it plays, highlight lines (they save with their timestamps), and ask about the part you didn't follow instead of rewinding three times. Our YouTube notebook page shows the flow, and the podcast page covers audio.
You do part of the work
Gistr will summarise for you when you ask. But the notebook is set up so the useful stuff (timestamped notes, clips, highlights) comes from you, while the material is playing next to you.
That sounds like more effort, and it is, a bit. It's also the effort that makes you remember. A note you wrote at minute 42 of a lecture, linked back to minute 42, is worth more on revision night than a paragraph the AI wrote about the whole thing.
Remembering gets its own space
Understanding a topic on Tuesday doesn't mean you'll have it in three weeks. So we built Study Space (still in beta). It turns a thread into a reading, flashcards and a quiz made from your own sources, and every answer points back to the passage it came from. Cards come back just before you'd forget them, with a small daily goal and a streak.
You can also build a study plan from a book or a course, with a quick level check first and your exam date in view. For NEET or UPSC prep, where you revise the same syllabus for months, a schedule that keeps bringing material back is worth more than another summary.
Capture happens where you already read
Learning material arrives from everywhere. The Chrome and Firefox extension lets you add pages and videos while you browse, and the iOS and Android apps keep your library with you.
What we chose not to build
Saying no is the harder half of picking a job, so here's where we drew lines.
We didn't make the AI summary the finished product. It's a starting point inside a thread, and the thread keeps going after it.
We didn't make audio recaps the centre of Gistr. Gistr can make a podcast from your sources, but if listening to a recap is the main thing you want, Gemini Notebook does it better and it's their signature feature.
We didn't try to win on free-tier volume. Gistr Free gives you 500 AI credits a month, 5 collections and 5 sources per thread. That's tighter than Gemini Notebook's 50 sources per notebook. If you want to throw 40 PDFs into one notebook for free, Google wins that one, and we're fine saying so.
And we haven't chased deep Google Workspace integration. If your school or lab runs on Drive, and you want imported Docs and Slides to stay in sync, that's a real reason to stay with Google.
Who should use NotebookLM instead
Honestly? Quite a lot of people. Pick NotebookLM (Gemini Notebook) if:
- Your sources are mostly PDFs, Google Docs and Slides.
- You like listening to an Audio Overview on the bus.
- You need lots of sources in one notebook on a free plan.
- Your school already uses Google Workspace.
Gistr makes more sense if:
- A lot of your learning comes from YouTube lectures, podcasts and articles, and you want notes next to the player.
- You want flashcards and quizzes that come back on a schedule, and a study plan built around an exam date.
- You save things while browsing and want them on web, phone and browser.
- You teach, and want to turn your sources into a presentation or a quiz for a class.
Plenty of people use both: Gemini Notebook for a big reading list, Gistr for lectures and revision. Nothing stops you.

Try it on something you're studying this week
- Paste a YouTube lecture link into a new thread. Gistr imports and transcribes it, usually in under a minute.
- Add the PDF or slides that go with it to the same thread.
- Watch, take notes and clip the parts you'd want to see again.
- Open Study and make flashcards and a quiz from the thread.
Then see how much of that lecture you still have next week. That's the test we care about.

FAQ
Is NotebookLM still called NotebookLM?
No. Google renamed NotebookLM to Gemini Notebook on July 16, 2026. Google says it is the same product, existing notebooks still work, and old links redirect.
Is Gistr a good NotebookLM alternative?
Yes, if much of what you study is video or audio. Gistr plays YouTube videos and podcast episodes inside the notebook with a synced transcript, timestamped notes and clips. NotebookLM imports only the text transcript of a YouTube video.
Which one is free?
Both have free plans. Gemini Notebook's free tier allows 100 notebooks and 50 sources per notebook. Gistr Free gives 500 AI credits a month, 5 collections and 5 sources per thread, with no credit card.
Can both make flashcards and quizzes from my own sources?
Yes. Gemini Notebook can generate flashcards and quizzes. Gistr makes readings, flashcards and quizzes in its Study Space, brings cards back just before you would forget them, and can build a study plan around your exam date.
Which is better for audio summaries of my notes?
Gemini Notebook. Its Audio Overviews and Video Overviews are its best known features. Gistr can make a podcast from your sources too, but if listening to a recap is the main thing you want, start with Gemini Notebook.
