| Compare | Microsoft OneNote Online | Obsidian |
|---|---|---|
| Verdict | Worth it | Depends |
| Best for | Students and educators | Personal knowledge bases |
| Who it's not for | Markdown and plain-text minimalists | Teams needing shared, out-of-box collaboration |
| Privacy | No known public vulnerabilities found in the sources reviewed; Windows 10 app support is ending, so avoid outdated versions.³ | Private, local-first design with third-party audits, but the plugin ecosystem has attracted real malware abuse. |
| Support quality | Official forum questions left unresolved | No direct support-quality evidence found. |
| Public sentiment | Users value free cross-device capture and Microsoft 365 integration but report web editing failures and look for alternatives elsewhere.⁴ | Users love the flexibility and adaptability but frequently flag the steep learning curve, and some long-time fans are drifting away.11 |
| Biggest gotcha | Notes live in OneDrive; leaving Microsoft means manual export and reformatting | Malicious plugins have been abused to deploy malware; vet third-party plugins carefully. |
