From my experience with Obsidian, I found it excels at helping users build a deeply interconnected knowledge base through its bidirectional linking and graph visualization features. Spending time with the platform reveals its strength in flexibility and customization, making it ideal for researchers, writers, and productivity enthusiasts who want full control over their notes. However, the learning curve can be steep for beginners, and collaboration features are limited compared to cloud-based tools. Overall, if you need a powerful, privacy-focused markdown note-taking app for personal knowledge management, Obsidian delivers robust and adaptable solutions.
