Gemini Notebook is built for querying documents rather than quick skimming. Upload multiple PDFs, URLs, or YouTube links, and every answer cites exact sources. It includes audio overviews and generous free limits with a Google account, though it requires uploading sources first.
Lilys AI is tailored for fast skimming. Paste a YouTube link or PDF to get instant Korean summaries and interactive timelines. As a Korean service, the UI and text flow naturally, but exact citations are weak and the free tier limits monthly usage and video lengths.
These two serve different purposes. Use Gemini Notebook for materials requiring accurate citations (papers, contracts, reports). Choose Lilys for content you need to grasp quickly (lectures, articles, recordings). Gemini Notebook is great for students thanks to generous free tiers, while heavy Lilys users may need a paid plan.
