5 Three-Way Comparison Points
-
1
Data Storage: Cloud vs Local vs Email
Notion stores everything in the cloud, depending on Notion's service. Obsidian saves plain text Markdown in local folders, guaranteeing full data ownership. Simple Memo - for Obsidian delivers notes as emails to your inbox — no dependency on any specific service or file management system. Each of the three has a fundamentally different data philosophy. -
2
Launch Speed

5
Monthly Cost Comparison

Cloud vs Local vs Email: Three Philosophies of Data Storage
Notion, Obsidian, and Simple Memo - for Obsidian hold fundamentally different philosophies about data storage. Notion is cloud-first. Access from anywhere, easy team sharing, but dependent on Notion's service. There are risks of service shutdown or account suspension, and you don't have complete control over your data. Obsidian is local-first. Files are saved as Markdown on your device with full data ownership. However, syncing across devices needs another service (Obsidian Sync from $4/month billed yearly, or iCloud; Dropbox isn't officially supported on iPhone). Simple Memo - for Obsidian is email-first. Memos arrive in your inbox as emails, with no dependency on any specific service or file system. Receivable via Gmail, Outlook, Yahoo! Mail, or any email service. No sync needed, no vendor lock-in. Sent memos stay readable in your inbox for as long as you keep that email account. Each approach has tradeoffs. Cloud balances convenience against vendor dependency. Local balances ownership against sync complexity. Email offers universality and simplicity, but organization is limited to your inbox's capabilities.
If Neither App Satisfies You
Both Notion and Obsidian are powerful tools for organizing and managing knowledge. For capturing a thought and sending it to your own inbox in the same step, the workflows differ. Notion took 2.8 seconds to be ready to type in our measurement (iPhone 16e, warm launch). Obsidian's iOS 26 Quick Capture is described in its 1.14 early access changelog and primarily saves to the vault. Simple Memo was ready to type after 0.4 seconds in our iPhone 16e warm launch test; after writing, you can send the same memo to email and Obsidian. You can still organize it later in Notion or Obsidian.
FAQ
Local storage vs cloud storage — which is actually safer?
Each has trade-offs. Obsidian's local storage keeps your files on your device even if the service ends, but is vulnerable to device failure or backup neglect. Notion's cloud storage offers automatic backups but carries risks of service outages or account suspension. Memos you send with Simple Memo - for Obsidian arrive in your inbox as emails, so you can still read them there if your phone breaks (how long they stay, and whether they can be restored, depends on your email service).
Which is better for knowledge management, Notion or Obsidian? And how is "capture" different?
For knowledge management (structuring, linking, long-term storage), Obsidian's backlinks and graph view are powerful, and Notion's databases are equally useful. "Capture," however, is about recording thoughts the instant they appear — no structure needed. Simple Memo - for Obsidian specializes in capture; Notion and Obsidian specialize in knowledge management. Separating these roles is the most efficient approach.
Is Obsidian's plugin ecosystem really necessary? Isn't Notion enough on its own?
Notion's built-in features cover many needs. However, Obsidian plugins add extensions such as spaced repetition and Dataview queries that run on your local Markdown files. For those who want full control over their workflow, Obsidian's plugins are valuable. And in either case, instant input is most comfortable when delegated to Simple Memo - for Obsidian.
What's the best workflow combining Notion, Obsidian, and Simple Memo - for Obsidian?
The recommended approach is a three-layer system: Simple Memo - for Obsidian for instant email capture (capture layer), Notion for project and team information management (collaboration layer), and Obsidian for building your personal knowledge graph (thinking layer). Each excels in a different area, complementing rather than competing with each other.
Both Notion and Obsidian feel heavy. Is there a lighter way to take notes?
The steps before typing depend on your device, settings, and entry point. Obsidian also offers shortcuts and iOS 26 Quick Capture in early access. If you want the same memo in your inbox and Obsidian vault, you can write and send it with Simple Memo - for Obsidian. Our 0.4-second measurement covers the tap to ready-to-type on an iPhone 16e warm launch, not the time to send the memo.
