Where NotebookLM stops

3 gaps NotebookLM leaves open for students

Loved the audio overview? Here's what's still missing when exam week hits.

Gap 01

No live lecture capture

“Class started 3 minutes ago — your laptop is still on the notebook screen.”

Truth: NotebookLM ingests sources you already have; it doesn't record class.

ThetaWave records and transcribes the lecture in real time, then drops it into your study workspace.

Gap 02

No native study kit

““Make me 40 flashcards from chapter 6.” — possible, but a manual chat loop every time.”

Truth: Flashcards, quizzes and mind maps live as prompts, not as first-class outputs.

ThetaWave generates flashcards, quizzes and mind maps from any source in one click.

Gap 03

Source caps on big courses

“Add the 51st reading… you're already past the limit.”

Truth: A full semester of slides, PDFs and recordings is more than one notebook holds.

ThetaWave is built for the volume a real course actually produces — no notebook-by-notebook juggling.
