| Compare | ||
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Students writing theses | Academic paper co-authoring |
| Who it's not for | Teams needing a battle-tested editor . Overleaf's track record is far deeper | Writers who don't need LaTeX markup |
| Privacy | No known public vulnerabilities found in the sources reviewed.⁸ | FedRAMP-authorized for government use; two moderate CVEs disclosed Sept 2024; open-source with public advisories. |
| Support quality | No support evidence in sources | No reliable support-rating evidence in sources |
| Public sentiment | Reviews are scarce: 2.5/5 on G2 from just three reviews, with scattered positive posts about its collaborative editing.¹ | Users broadly treat Overleaf as the standard for collaborative LaTeX but gripe about free-tier limits, recent product changes, and whether Pro is worth paying for. |
| Biggest gotcha | Public pricing not surfaced in reviewed sources . confirm exact costs before paying.² | Free plan limits (collaborators, compile time, storage) are the main upsell trigger . check before committing. |
