Tools for academics
LaTeX tools and AI manuscript review
A growing set of academic tools: free in-browser utilities for LaTeX, citations, and document conversion, plus a paid AI Paper Review red team. The free tools process files in memory and never store them. The paid Paper Review tool discloses its data handling on its own page.

Privacy-respecting tools, free and paid
The free tools are LaTeX, citation, and conversion utilities for academic authors — compile to PDF, convert to and from Word, diff versions, validate BibTeX, render equations, and more. They run in your browser against a hosted backend; your files are processed in memory and discarded the moment your download is ready, so unpublished manuscripts stay private.
The paid Paper Review tool runs an AI red-team review of an uploaded manuscript. Because that review depends on a third-party language model (Anthropic's Claude API), its data-handling guarantees are necessarily different from the in-house free tools; the Paper Review page discloses retention details clearly before you upload.
