Obsidian
A local-first Markdown workspace for linked notes and personal knowledge.
Obsidian is a note-taking and knowledge-base app built around local Markdown files. It helps users connect ideas with links, backlinks, graph views, canvases, plugins, and optional services for encrypted sync and publishing notes as a website.
Why it stands out
- Stores notes as plain local files, making them portable and usable outside the app.
- Combines wiki-style linking, visual graphing, and freeform canvas work in one workspace.
- Large plugin ecosystem supports highly customized workflows beyond the core app.
- Optional sync is designed around end-to-end encryption and per-device file controls.
- Publishing works directly from the app for turning connected notes into browsable websites.
Good to know
- Sync, collaboration, and publishing are separate services rather than just part of the free local app.
- Advanced workflows may rely on community plugins, which can vary in maintenance and complexity.
- The local-file model is powerful but may feel less straightforward for users who want a purely web-based collaborative workspace.
Under the radar: If you plan to keep notes for years, organize them as normal folders and Markdown files first, then add plugins later; this keeps the vault readable even if your setup changes.

Researchers, writers, students, and knowledge workers can build a private, long-lived personal knowledge base without locking notes into a hosted database. Map relationships between books, projects, people, and ideas using links and the graph view. Use Canvas to plan essays, lectures, product work, or research visually. Turn a folder of notes into a team wiki, documentation site, or public digital garden. Extend the app with community plugins for tasks, calendars, kanban boards, outlines, and custom queries.
Local Markdown-based note storage, internal links and backlinks, interactive graph view, Canvas for visual thinking, plugin and theme ecosystem, optional end-to-end encrypted sync, version history, shared vaults, selective sync, and Obsidian Publish for creating online note sites.
