|---|---|---|
| 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 |

| 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. |
