Instant preview. Real Git. AI that knows LaTeX. 3 free collaborators.
Built for PhD students and researchers who are done with compile timeouts.
Not a gimmick. Not just an AI wrapper. A genuinely faster, more capable LaTeX environment for people who write papers for a living.
Underrock uses aggressive latexmk caching and incremental recompilation. Most edits preview in under 5 seconds. No compile timeout. No forcing you to buy a plan to compile your thesis.
No timeouts, everOur AI doesn't just fix grammar. It completes environments, generates TikZ figures from plain English, formats BibTeX citations, fixes package conflicts, and adapts your template to any target journal — IEEE, NeurIPS, ACM, Nature, and more.
Unlimited on ProUnderrock connects to your GitHub or GitLab repo as a proper Git remote. Not a commit-per-keystroke translation layer. Branch, merge, review pull requests — exactly the workflow you use for code.
Free on Pro planWork with your advisor and a labmate without pulling out your credit card. See live cursors, leave comments, track changes — all included on every plan, not gated behind a $200/yr paywall.
Free foreverSearch 2,000+ journal and conference templates. Submit to IEEE Transactions and then NeurIPS the same month — one click adapts your project's structure, references, and formatting to the new target venue.
Coming to Early AccessIf your institution's IT policy requires GDPR-compliant data residency, Underrock Enterprise keeps your documents in EU infrastructure. No US cloud dependency. On-premises available.
EnterpriseAn honest comparison. We're early, but we're better where it matters most.
