Sublime
Depends
Confidence: Low
Low confidence: only three usable sources, but Sublime looks like a $100/year personal 'second brain' notes app with a free tier.
Comparison
Sublime vs Obsidian
Sublime and Obsidian both land on Depends.
Obsidian
Depends
Confidence: Medium
Buy it if you're an individual who wants a powerful, private, local-first knowledge base and will invest time learning it.
| Compare | Sublime | Obsidian |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Individuals building a personal 'second brain' | Personal knowledge bases |
| Who it's not for | Teams needing shared docs, roles, or permissions | Teams needing shared, out-of-box collaboration |
| Privacy | No known public vulnerabilities found in the sources reviewed.⁴ | Private, local-first design with third-party audits, but the plugin ecosystem has attracted real malware abuse. |
| Support quality | No support evidence found | No direct support-quality evidence found. |
| Public sentiment | Evidence contains almost no user reviews of this specific product . nearly all 'Sublime' reviews online cover the band, Sublime Text, or Sublime Security.³ | Users love the flexibility and adaptability but frequently flag the steep learning curve, and some long-time fans are drifting away.⁷ |
| Biggest gotcha | Free-tier caps are unclear from reviewed sources; confirm limits before relying on it¹ | Malicious plugins have been abused to deploy malware; vet third-party plugins carefully. |
