Monolog is a note-taking and learning management application that adopts modern technologies and practices the retro Zettelkasten concept. It advocates using two-way links and hierarchical tags to record, organize, and review your ideas. More importantly, once you get used to using two-way links, you will unconsciously enter the divergent thinking mode when thinking, actively looking for connections between ideas, which helps you think better. Monolog is native, can be used offline, and stores data locally first, being private and secure. There are also daily reviews and visual charts to monitor and statistics your growth.
