Developers & Tech Users
Good FitComfortable with Markdown, plugins, and local file systems - a natural fit
Non-Technical Users

vs. Competition
Obsidian competes with other personal knowledge management tools. Here's how it stacks up on key factors.
Obsidian wins on data ownership and cost - it's the only major PKM tool that's truly free with local storage. Notion offers better collaboration but locks your data in their cloud. Logseq is the closest alternative with similar philosophy but uses an outliner approach that's love-it-or-hate-it.
