I've been building a bookmark manager (note-taking app) manually for 3 years

Metaessen.com is not only a bookmark manager but also a note-taking app. It can manage bookmarks, notes, tasks, projects, ideas, and more.

Main features:

- Practical and concise philosophy [1]

- Innovative Resource-Instance-System data model (similar to file system) [2]

- Simulate the real world (e.g. Use the above data model to simulate the structure of things; Limit the character number of resource content to simulate the A4 page in real world)

- Search and Filter

- Support Markdown and Plain Text

- Clean and concise User Interface (UI)

- Safe and protect Security and Privacy

- REST API

- Web Clipper [3]
