SilverBullet

SilverBullet is a powerful, markdown-based personal knowledge management tool and note-taking app optimized for people with a hacker mindset. It stores all notes as plain markdown files and extends them with a live query and template system that lets you create dynamic, database-like views within your notes.

Key features include live queries that pull data from across your note space into any note, slash commands for quick insertion of templates and snippets, a command palette, full-text search, backlinks, a rich plugin system (Plugs), and a web-based interface that works offline. SilverBullet is serverless — it runs entirely in the browser for a single user, or can be hosted on a server for access from multiple devices.

For Obsidian or Notion users who want something more programmable and self-hostable, SilverBullet's live query engine and template system provide a uniquely powerful approach to building a second brain and personal knowledge base.
