NotebookLM - renamed Gemini Notebook in July 2026 - is Google's source-grounded AI notebook: upload your notes and textbooks and it answers with citations, builds mind maps, and turns your material into podcast-style audio and video overviews. It's free, brilliant at digesting your own materials, and completely unaware of Australian curricula. Polarbear starts where it stops: marking essays against VCE/HSC/QCE criteria, exam-style practice, and official-data ATAR tools.

Trying it takes two minutes

Our verdict
NotebookLM is the best free tool there is for studying your own materials - the audio and video overviews have no real rival, and Google keeps shipping. But by design it only knows what you upload: no Australian curriculum awareness, no criteria-based marking, no exam-style practice, no admissions data. Polarbear is the curriculum layer on top. Genuinely complementary.
Frequently asked questions
Is NotebookLM free for students?
Yes - personal Google accounts (13+) get a generous free tier with daily limits on chats and audio/video overviews, and schools can enable it through Google Workspace for Education. Higher limits come bundled with Google's paid AI plans.
What happened to the NotebookLM name?
Google renamed it Gemini Notebook in July 2026 as it integrates with the Gemini app. Same product - most people still call it NotebookLM.
Can NotebookLM mark my essays?
It can discuss a draft you upload and give general feedback, but it doesn't mark against VCE/HSC/QCE assessment criteria - it has no curriculum awareness by design. Polarbear's Essay Marking is built for exactly that.
