For students juggling notes, research, and tasks, Obsidian's local-first, markdown-based system offers incredible flexibility and long-term data ownership, which is a huge plus. Its graph view is fantastic for seeing connections between ideas, and community plugins can add almost any functionality you can imagine, like advanced task management or calendar integration. The learning curve is steeper, but the payoff in terms of customization and privacy is substantial. Notion, on the other hand, excels in its all-in-one, database-driven approach. It's more user-friendly out of the box for organizing structured information like syllabi, assignments, and project plans with its templating and property features. Its collaboration tools are also superior if you work on group projects. If your primary need is a polished, integrated solution for tracking assignments and basic note-taking with less setup, Notion might be quicker to get started with. If you foresee needing deep customization, powerful interlinking for complex subjects, and want your data locally, Obsidian is the way to go, even if it takes more initial effort.
