The knowledge management system that grows with you.

Start with a folder of markdown notes on your local machine. Grow it into your team’s shared memory. Or your product’s public documentation. Same tool, same files, fully under your control.

Collaborate with your team with tasks, comments and mentions

1 · Your private thoughts

Open a folder, start writing. Journal, keep tasks, collect ideas, and link them together as you go. It’s all markdown files on your own computer, and nothing leaves it unless you want it to.

2 · On every device you own

Run a server of your own, or pick a host, and your notes follow you to every device. On your phone, SilverBullet installs straight from the browser as a home screen app. It keeps working offline and catches up when you’re back online.

Personal knowledge →

3 · For your team

Share a space and work on it together in real time: assign tasks with @-mentions, discuss in comments, and see edits appear as they happen. Or keep your docs next to your code in git, and review changes like any other pull request. Same markdown either way.

Team knowledge →

4 · For the world

Publish a space as a website, read-only, styled your way. SilverBullet’s own documentation is an example of this.

Publishing →

The SilverBullet documentation at docs.silverbullet.md, itself a published SilverBullet space: a section tree on the left and the Start page on the right

Find your path

Accruing knowledge is one thing, finding your way through it is another.

Follow links.

Link a thought to the next one, and the one after that. Linking as you write is how notes turn into knowledge.

See what links back.

Every page shows everywhere else it’s mentioned, so connections you made months ago surface on their own.

See the shape of it.

The object graph draws your pages and how they relate, so you can wander through them visually.

Ask questions.

Query your notes like a database: open tasks across every project, everything tagged #decision, the pages you touched this week.

Exploring your knowledge →

Built to last as long as your knowledge does

Make it yours.

Start with a great editor and add what you need when you need it: live queries, custom commands, your own styling, libraries others have shared. SilverBullet changes shape with you instead of making you change shape for it.

${query[[from t = index.tasks() where not t.done
  order by t.page desc
  select templates.taskItem(t)]]}
The Open tasks list on the index page: unticked tasks from the shopping list, the photo club meetup, the house move and journal days, each linking back to where it was written

How it adapts →

Your files, forever.

Your notes are markdown in an ordinary folder, next to your images and PDFs. Open them in any editor, put them in git, back them up however you like. If SilverBullet disappeared tomorrow, your knowledge wouldn’t.
