How-tos for LaTeX and academic writing.
The LaTeX studio built for how researchers write.
ModernTex is a native macOS manuscript studio. Multi-file editing, a PDF preview that stays in sync, citation management, and submission-readiness checks. It's shaped around the manuscript workflow, not a generic text editor.

Before you submit
Find what Reviewer 2 will find, first.
Paper Review puts your manuscript in front of four AI reviewers (a methodology critic, a statistical skeptic, a data integrity officer and an editor), checks every reference against CrossRef and scans the figures. You get a prioritized list of fixes, quoted from your own text, in minutes. No account. The manuscript and the review are deleted 30 minutes after you first open the result, or after 24 hours if you never open it.
Not ready to pay? The free submission checklist walks through the twelve checks worth doing, and can email you a week before your deadline.
Buying for a lab? Volume packs, invoices and a W-9 are on the labs page.
Critical blind spots
Sample-size justification missing for the human evaluation. Quoted: “We recruited 24 annotators … yielding sufficient statistical power.” Fix: report a sensitivity analysis (the smallest effect 24 annotators can detect) and confidence intervals.
Data-to-claim contradictions
Claim: “Our method beats all baselines by a wide margin.” Table 2 shows it tied with Baseline C within standard errors on 4 of 7 datasets.
Rectification checklist
- A Add the hyperparameter search protocol to Section 3.2.
- B Reference [17] only weakly matches CrossRef; check its title and DOI.
- C Redraw Figure 3 without the broken y-axis.
