Security reflects where data goes, requested permissions and incidents on record at the verification date. It is not a guarantee of zero risk: check the deployment mode and the connections you enable.

What it does, concretely

Many note-taking tools store your data on third-party servers, raising questions about privacy and long-term access. Obsidian addresses this by saving all your notes locally on your device as plain Markdown text files, with no one else able to read them.

In practice, you create notes in a local folder called a vault, link them together with internal links, visualize their relationships through an interactive graph, or lay them out on an infinite canvas. Thousands of community plugins, including AI plugins such as Copilot or Smart Connections, let you connect a language model of your choice directly to your notes.

Obsidian is designed for people who want to build a lasting personal knowledge base: researchers, writers, students, and information management professionals. The open Markdown format ensures your data remains readable and portable over the long term.

That said, the tool requires a learning curve and a taste for customization. People looking for a ready-to-use solution with no configuration may find the breadth of options overwhelming.

What it offers

  • ·Local storage of notes as plain Markdown text files, accessible offline and readable by any text editor.
  • ·Internal links between notes to build a personal wiki and navigate between ideas.
  • ·Interactive graph to visualize connections across all your notes.
  • ·Canvas feature to organize and connect notes in an unlimited visual workspace.
  • ·Library of thousands of community plugins, including AI plugins (Copilot, Smart Connections) connected to the model of your choice.
  • ·End-to-end encrypted sync across devices with one year of version history per note (paid).
  • ·Publishing notes as a website with custom domain and password protection (paid).
  • ·Collaboration on shared vaults without compromising private data (paid).

How to install Obsidian + plugins IA

1. Go to obsidian.md and download the version for your system (Windows, macOS, Linux, iOS, or Android). 2. Install the app and create a new vault in a local folder of your choice. 3. Get comfortable with basic notes, internal links, and tags before adding plugins. 4. To add an AI plugin, open Settings > Community Plugins, disable restricted mode, then search for "Copilot" or "Smart Connections". 5. Follow the plugin instructions to enter your API key for the language model of your choice: never share this key and store it in a password manager. 6. If you want to access your notes across multiple devices, enable Obsidian Sync (paid) to benefit from end-to-end encryption.
