SilverBullet is a note-taking application optimized for people with a [hacker mindset](https://en.wikipedia.org/wiki/Hacker). We all take notes. There’s a million note taking applications out there. [Literally](https://www.noteapps.ca/). Wouldn’t it be nice to have one where your notes are _more_ than plain text files? Where your notes essentially become a _database_ that you can query; that you can build knowledge custom applications on top of?
Absolutely. You use SilverBullet to quickly jot things down. It’s a notes app after all. However, this is just the beginning. Gradually, you start to annotate your notes using [[Frontmatter]]. You realize: “Hey, this note represents a _person_, let me [[Tags|tag]] it as such.” Before you know it, you’re turning your notes into [[Objects]]. Then you learn that in SilverBullet you can [[Live Queries|Live Query]] these objects. Your queries grow into reusable [[Templates]] written using a powerful [[Template Language]]. You find more and more uses of these templates, for instance to create [[Page Templates|new pages]], or [[Live Template Widgets|widgets]] automatically added to your pages.
SilverBullet is open source **personal knowledge management system** implemented as an offline-capable web application ([[PWA]]). In order to use it, you have to **self-host** it: that is, you need to run a web server either on your own machine, somewhere on your network, or in the cloud somewhere. See our [[Install|installation instructions]]. Yes, this requires a bit more work than downloading a desktop app. But get a lot in return.
* SilverBullet is a **web application** and therefore instantly accessible wherever a (modern) web browser is available, without the need to install a 200mb Electron app, nor unreliable or proprietary sync setups.
* SilverBullet is a [[PWA]] that supports two [[Client Modes]]: [[Client Modes#Online mode]] and [[Client Modes#Synced mode]]), where the _synced mode_ enables **100% offline operation**, keeping a copy of the content in the browser’s local ([IndexedDB](https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API)) database, syncing back to the server when a network connection is available.
* **Self-hosted**: _you own your data_. Your [[Spaces|space]] is stored as plain files in a folder on disk on your server. Back it up, sync, edit, publish, script it with any additional tools you like.
* SilverBullet provides an enjoyable [[Markdown]] writing experience with a clean UI, rendering text using [[Live Preview|live preview]], further **reducing visual noise** while still providing direct access to the underlying markdown syntax.
* SilverBullet supports wiki-style **page linking** using the `[[page link]]` syntax. Incoming links are indexed and appear as [[Linked Mentions]] at the bottom of the pages linked to, thereby providing _bi-directional linking_.
* SilverBullet is a platform for [[End-User Programming]] through its support for [[Objects]], [[Live Queries]], [[Live Templates]] and [[Live Template Widgets]], allowing to make parts of your pages and UI dynamic.
* SilverBullet allows you to boost your writing/knowledge collection productivity using its various [[Templates]] mechanisms including powerful [[Snippets]] and [[Page Templates]].
