Comparison
Obsidian for People Notes vs a Relationship Memory App
Obsidian and PKM tools hold people notes, but they're document-first. Compare them with a person-first relationship memory app for pre-meeting recall.
Obsidian can absolutely hold notes about people, and for committed users it does it powerfully, but it is document-first, which means relationship recall takes deliberate structure and ongoing upkeep. A relationship memory app is person-first by default, so the recall you want before a meeting is built in rather than something you have to design. Which fits depends on how much system-building you enjoy.
This is not Obsidian versus a worse tool. It is a question of where the work lives: in your setup, or in the app’s defaults.
How people notes work in Obsidian
Obsidian users tend to build a personal “people” system out of the tool’s primitives. The usual ingredients are:
- A note per person, often from a template.
- Backlinks connecting people to projects, events, and each other.
- Daily notes where you jot what happened, then link to whoever was involved.
- Dataview queries to pull “everyone I owe a follow-up” into one view.
Done well, this is genuinely impressive: a queryable graph of your relationships that you fully own, in plain text, on your own machine. The catch is that “done well” requires designing and maintaining it.
Document-first vs person-first
The core difference is the default unit. In Obsidian, the default unit is the document. In a relationship memory app, the default unit is the person.
| Dimension | Obsidian (PKM) | Relationship memory app |
|---|---|---|
| Default unit | A document/note | A person |
| Capture | Open vault, find or make a note | Save a note in seconds, on the go |
| Recall before a meeting | Run a query or open the right note | Person view is built in |
| Reminders with context | Plugins or external tools | Native and reason-aware |
| Maintenance | You design and maintain the system | App handles structure |
| Ownership | Total, in plain-text local files | Depends on the app |
That last row is Obsidian’s real strength: nothing beats plain-text files you control. The trade is everything above it: the speed and the no-setup recall you get when the app is already organized around people.
The maintenance tax
The hidden cost of a PKM people system is upkeep. Templates drift, links rot, and the daily-note habit is the first thing to lapse in a busy week. A system that depends on your discipline tends to decay exactly when you are too busy to maintain it, which is when you most need it.
A relationship memory app moves that burden into the app. You capture a line; the structure is already there. Compare a typical PKM-style entry with a captured note:
Spoke with Lena at the AI policy roundtable. Advises two non-profits on data governance, skeptical of vendor hype. Mentioned her son is applying to conservatories. Open to reviewing our privacy approach if I send a short brief. Follow up next week with one page, not a deck.
In Obsidian you would create or open Lena’s note, paste this, and link it to the event and any projects. In a person-first app you save it once and it already lives on Lena’s profile, searchable, with a reminder attached. The difference is friction, and friction is what decides whether a system survives.
When Obsidian is the better choice, and when to add a layer
Be honest about your own tendencies.
Stick with Obsidian if:
- You already run a vault and enjoy maintaining it.
- You want total ownership and plain-text portability.
- Your people notes are deeply intertwined with projects and research.
Add a dedicated relationship memory layer if:
- You capture on the go and want zero setup before recall.
- Your people system keeps decaying despite good intentions.
- You want reminders that carry the reason, not just the name.
Even committed PKM users often run both: Obsidian for deep work and synthesis, a fast app for in-the-moment people capture. The principle behind either is the same one in our guide to taking better contact notes: capture the context, not just the contact.
Key takeaway: Obsidian is a powerful, fully owned home for people notes if you enjoy building and maintaining the system; a relationship memory app gives you person-first capture and recall by default, with far less upkeep. Choose based on how much system-building you actually keep up.
FAQ
Can Obsidian be used as a personal CRM?
Yes, with a note-per-person template, backlinks, and Dataview queries you can build a capable relationship system. It works well if you maintain it, but it is document-first, so recall and reminders require deliberate setup.
Is a relationship memory app better than Obsidian for people?
Not better, different. A memory app is person-first and lower-maintenance, which suits on-the-go capture and pre-meeting recall. Obsidian wins on ownership, depth, and integration with your wider notes.
Can I use both Obsidian and a relationship memory app?
Yes, and many people do. Use Obsidian for deep notes and synthesis, and a dedicated app for fast people capture, recall, and reminders. They serve different moments.
Pick the one that survives a busy week
The best system is the one still running when you are slammed. For some people that is a beloved Obsidian vault; for others it is an app that needs no upkeep. Match the tool to the discipline you actually have, not the one you wish you had.
