Obsidian

What makes Obsidian different

Most notes apps are SaaS-shaped: your notes live in their database, behind their auth, accessible only through their app. If the company pivots, raises prices, or goes under, your notes are stranded. Notion, Roam, Mem all share this risk.

Obsidian flips the model. Your notes are markdown files in a folder on your computer. The Obsidian app is a viewer and editor. If Obsidian disappeared tomorrow, you would still have every note in plain text, openable in any editor for the next 50 years.

For a one-person business, that durability is the killer feature. The compounding value of a personal knowledge base is real. You do not want to lose it because of a company decision out of your control.

What it is good at

• Backlinks and graph view. Type [[note name]] and Obsidian creates and tracks the link. Over time you build a personal knowledge graph that reveals connections you forgot.
• Daily notes. A built-in template that creates a note per day, useful for journaling, work logs, or capturing scattered thoughts.
• Search. Full-text across thousands of notes is instant, no indexing wait.
• Plugins. Calendar views, kanban boards, citation tracking, AI assistants. You can mould Obsidian into almost anything.

What it is not for

If you need to share notes with collaborators in real time, Obsidian is not the tool. Use Notion, Coda, or Google Docs for that. Obsidian Sync is fine for syncing your own notes across devices, but it is not collaboration.

If you want a tool that comes pre-configured with opinions, Obsidian will frustrate you. The empty vault on day one is intimidating. The community has plenty of starter setups and YouTube guides, which both helps and adds to the rabbit hole.

My setup

Three folders: Inbox (everything new lands here, processed weekly), Projects (active client and product work), Reference (anything I want to find again). Daily notes for journaling. The Templater plugin for new project templates. The Dataview plugin for one summary page that lists all open projects.

That is it. Five hours to set up. Pays back every week since.

Verdict

If you take notes seriously and you plan to keep doing it for the next decade, Obsidian is worth the learning curve. Free for personal use makes the trial cost zero. The escape hatch (your files in plain markdown) makes the lock-in zero.
