Looking for NotebookLM alternatives? I've been testing a few lately, like Otter for meeting notes and Mem for personal knowledge management. They each have their own spin—Otter transcribes in real-time, while Mem connects ideas like a second brain. OneNote is also solid for organizing research. Just depends if you need AI summaries or just a good note structure. What's your main use case?
