Google just gave its AI notebook tool a TikTok-shaped upgrade. NotebookLM can now generate roughly 60-second vertical videos from user-uploaded notes, turning research materials into bite-sized narrated slideshows complete with summaries, images, and diagrams.
The feature, called Short Video Overviews, is available exclusively to Google AI Pro and Ultra subscribers aged 18 and over. Free-tier users are either locked out entirely or limited to significantly fewer generations.
How the short video format works
The new Short format builds on NotebookLM’s Video Overviews feature, which first launched on July 29, 2025. Where the original format produced longer-form video summaries, the Short option condenses everything into a vertical, roughly one-minute clip designed for quick consumption.
Under the hood, the feature relies on Google’s Nano Banana 2 Lite model for rapid text-to-image generation, alongside Gemini-family models for the broader content processing. Users upload their notes and sources through the Studio interface, and the system produces a narrated slideshow that pulls key points, visuals, and diagrams from the uploaded content.
