Obsidian vs MS Word
Obsidian is a Markdown-based note-taking powerhouse with excellent note-linking abilities. You can easily build and navigate whole knowledge bases with Obsidian.
Word is a traditional word processor, allowing you to create and save documents, format text with headings, bold and italic, etc. It is suitable for everything, but not very good at one particular thing.
Fan of writing apps? 🤔
Maybe Paper is what you're looking for.
