Every Obsidian plugin list has the same problem: it tells you what each plugin does and never tells you whether you need it. So people install twenty on day one, the vault gets slow and strange, and they cannot work out which of the twenty is responsible.
This list is organised the other way round — by the job you are trying to do — and every entry says when to skip it. Because for most of these, skipping is the right answer.
The plugins, by job
| Plugin | The job it does | Skip it if |
|---|---|---|
| Calendar | Navigating daily notes | You do not use daily notes |
| Periodic Notes | Weekly and monthly notes | Daily notes alone are enough |
| QuickAdd | Fast capture without opening the vault | You rarely capture on the fly |
| Tasks | Due dates and recurring tasks inside notes | You track tasks in a real task manager |
| Kanban | Project boards | A checklist is enough |
| Templater | Templates with dynamic content | Static templates cover you |
| Dataview | Querying your vault like a database | Built-in Bases views already do it |
| Excalidraw | Hand-drawn diagrams inside notes | You do not sketch |
| Tag Wrangler | Renaming and merging tags in bulk | Your tag list is still small |
| Advanced Tables | Making markdown tables bearable | You rarely write tables |
| Smart Connections | AI-assisted search across your notes | See the warning below |
The one that needs a warning
Smart Connections does something genuinely useful — surfacing notes that are related to what you are writing, without you having linked them. It is also the one plugin on this list that can send the contents of your notes to an external AI provider, depending on how you configure it.
That is not a scandal; it is how the feature works, and the plugin lets you point it at a local model instead. But it deserves a deliberate decision rather than a default. People choose Obsidian specifically because their notes are plain files on their own disk, and then install a plugin that quietly changes that property. Open the settings and read them before you index a vault that contains client work, journals, medical notes or anything under an NDA.
Install one at a time
This is the single most useful habit with Obsidian, and almost nobody follows it: add one plugin, use it for a few days, then consider the next one.
The reason is diagnostic, not moral. When something breaks in a vault with twenty plugins installed on the same afternoon, you have no idea which one did it, and the only way to find out is to disable them one at a time — which is an evening you will not enjoy. A vault that grew deliberately tells you immediately what changed.
The second reason is that most plugins do not survive contact with your actual habits. Install Kanban, and in a week you will know whether you opened the board or ignored it. Install eleven at once and you will keep all eleven forever, because you never observed any of them individually.
Check the list once a year
Obsidian absorbs popular plugin functionality into the core app over time. Bases is the clearest recent example — a lot of what people installed Dataview for is now built in, which means some vaults are running a heavy community plugin to do something the app already does natively.
So once a year, go through the installed list and ask three questions of each one: have I used this in the last month, does core Obsidian do it now, and is it still being maintained? An unmaintained plugin is not an emergency, but it is a thing that will eventually break after an app update, and it is better to find that out on purpose than in the middle of something.
That last point matters more in Obsidian than in most apps, because plugins are community-built and a maintainer can simply stop. Your notes are safe either way — they are markdown files on your disk, which is the whole argument for Obsidian — but the view of them can break.
If you are starting today
Install nothing for the first two weeks. Write notes in plain Obsidian and see what actually annoys you.
Then install exactly the plugin that fixes the specific annoyance you noticed. If tables are painful, Advanced Tables. If capture is slow, QuickAdd. If you cannot find anything, Dataview or Bases. This sounds slower than following a starter list, and it produces a vault you understand and a set of plugins you use.
The failure mode of Obsidian is not missing features. It is spending three weeks building a system instead of writing notes in it — the same trap that catches people in flexible tools generally, which we covered in Notion vs Obsidian.
If you are still choosing a note app, Obsidian against OneNote covers the other common comparison, and the sync options are here — including the free ones.
