We built LumenAI to solve a single problem: NotebookLM doesn't have real chat functionality. Upload your entire collection of PDFs and documents, ask questions, explore connections, and dive deep through natural, continuous conversations that actually remember your context. Unlike NotebookLM's fragmented one-chat-per-notebook design, LumenAI delivers genuine multi-threaded discussions with seamless continuity across your entire research project.

Convert any YouTube, MP3, MP4, or PDF into transcripts, summaries with 99% accuracy, mindmaps, or quizzes. Use the integrated AI chat to search your documents instantly.
