A second brain,
for you, forever.
Obsidian is a powerful knowledge base on top of
a local folder of plain text Markdown files.
The human brain is non-linear: we jump from idea to idea, all the time. Your second brain should work the same.
In Obsidian, making and following connections is frictionless. Tend to your notes like a gardener; at the end of the day, sit back and marvel at your own knowledge graph.
GRAPH VIEW
The graph is your knowledge at a glance. Explore, observe, and stay motivated. With group, filter, and display options, see things your way.
Local graph shows connections around you. Get inspired while writing.
BACKLINKS

Broaden your view to see this note in other contexts. Link relevant pages with one click.
OUTGOING LINKS

Note-taking is incredibly personal. Tried every app, but something always irks you? You deserve better.
For those who can’t custom-build a solution for themselves, Obsidian is as close as you can get, with plugins, themes, and custom CSS at your disposal.
YOUR KNOWLEDGE BUILDING BLOCKS
Obsidian is built to be extensible from the ground up. We want you to build your own system, play with it, tweak it, until you’re happy.
Obsidian is a versatile toolbox: with
25 core and
community plugins, 60+ themes, plus custom styling, you can tweak Obsidian to work and look exactly how you want it.
MIX AND MATCH
Some community plugins do a single thing extremely well, like
Calendar and
Kanban. Others unlock endless possibilities:
Dataview and
Templater are great examples.
They are super easy to grab: the built-in plugin marketplace lets you install them with one click. And the sum of the parts is greater than the whole: some plugins work even better together.
DO IT YOURSELF
Looking for something unique? There’s no need to wait for someone else to make it! Whether you have programming experience or not, you can try your hands at making your Obsidian plugin.
All community plugins are available on GitHub if you like to study them. Our developer community is also here to help!
In our age when cloud services can shut down, get bought, or change privacy policy any day, the last thing you want is proprietary format and data lock-in.
With Obsidian, your data sits in a local folder. Never leave your life’s work held hostage in the cloud again.
FUTURE-PROOF FORMAT
Obsidian uses Markdown. Markdown is widely used by sites like Reddit and GitHub and not going away anytime soon.
Markdown is designed to be human readable. It’s not obfuscated by encoding; you can directly edit the source files with Markdown editors, or edit them automatically with scripts.
TOTAL CONTROL
Your notes live on your device, period. You can encrypt them or back them up however you want; it’s your decision, not ours.
Plain text files let you do various sync, encryption, and data processing on top of it. Obsidian plays nice with Dropbox, Cryptomator, and any software that works with plain text files.
ALWAYS AVAILABLE
No internet? No problem. Obsidian works completely offline, internet or service issues will never be your problem.
Enjoy reading and working on your notes anytime, anywhere.
