Obsidian

Obsidian is a versatile note-taking and knowledge management application that allows users to create, link, and organize their thoughts and information. It emphasizes local data storage, privacy, and extensibility through a rich plugin ecosystem. Users can sync their notes across multiple devices and publish them as online wikis or knowledge bases.

Obsidian is a note-taking and knowledge management application that stores notes locally on the user's device. While it offers features like syncing notes across devices (cloud storage integration) and version history, it does not primarily focus on AI-powered automated file organization, conversational AI for file management, or content-based queries as described in the Dynbox concept. Its core functionality revolves around linking notes, graph visualization, and extensibility via plugins, rather than automated file sorting or AI-driven content analysis. It does offer privacy controls by storing data locally and end-to-end encryption for sync. The 'Manual Approval Workflow' is partially matched through its version history and explicit sync controls, but not in the context of AI-proposed actions. It also has local file access and multi-tier pricing.
