Obsidian is a powerful and extensible knowledge base
that works on top of your local folder of plain text 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.
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.
With Obsidian, your data sits in a local folder. Never leave your life's work held hostage in the cloud again.
With more than 70,000 members in our Discord chat and 35,000 members on our forum, Obsidian has one of the largest note-taking communities.
Our community welcomes anyone who uses Obsidian or is interested in Obsidian, no matter your language, country, or field. Come join us!
