NemoMemo vs. Obsidian
A knowledge base vs. the notes that come before structure.
Obsidian is a serious tool for building a knowledge base: local Markdown files, backlinks, a graph, and a plugin ecosystem that can turn it into nearly anything. If you are cultivating a garden of connected, permanent notes, Obsidian is one of the best homes for it.
NemoMemo lives upstream of that. It is the web-based timeline for the raw stream — the TIL, the link, the half-thought — available from any browser because it runs on your server, shareable with the people on your reef, and self-cleaning where you want it to be. Both speak Markdown, so the notes that grow up can move.
Use Obsidian for…
- A permanent, linked knowledge base
- Local-first files on your own device
- Backlinks, graph view, and community plugins
- Long-form thinking and research
Use NemoMemo for…
- Quick capture from any browser, on any device
- A dated timeline rather than a folder of files
- Sharing single memos — with people or via expiring links
- The one-day notes Obsidian would keep forever
| Obsidian | NemoMemo 🐠 | |
|---|---|---|
| Shape | Vault of linked Markdown files | Chronological memo timeline |
| Where notes live | Local files (sync optional) | Your server, one SQLite file |
| Access | Desktop & mobile apps | Any web browser |
| Sharing | Via publish/sync add-ons | Per-memo visibility + share links |
| Ephemeral notes | Manual cleanup | Dory memos (24h) |
| Price | Free core, paid sync/publish | Free to self-host |
This is the least either/or comparison on the list: many people happily run both, capturing in NemoMemo and promoting the keepers into their vault. Markdown makes the handoff painless.
