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.

AI manuscript review · paid

Pay-per-use AI tools built for high-stakes academic work. Priced for the community — $1 to $8 per service. Volume packs for labs.

LaTeX manuscript tools

Compile, compare, and produce publication-ready artifacts from .tex sources.

Convert between formats

Move documents in and out of LaTeX, Markdown, and Word.

Citations and bibliographies

Build, verify, and convert reference lists across the major formats.

Utilities

A few odds and ends that pair well with the tools above.

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against a hosted backend; your files are processed in memory and discarded the moment your download is ready, so unpublished manuscripts stay private.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.

Frequently asked questions

Are these tools free?
The LaTeX and citation utilities are free with no account, no install, and no rate-limit beyond a daily fair-use cap. The Paper Review tool is paid (from $3 per review).
Do you store my files?
For the free tools: no. Files are processed in memory in an ephemeral container and discarded immediately — nothing is written to durable storage or logs. For the paid Paper Review tool: your manuscript is sent to Anthropic's Claude API, which retains inputs for 30 days for abuse monitoring (not for training). Purplelink itself does not retain the manuscript or the resulting review after delivery. See the Paper Review page for full details.
Do I need to install anything?
No. Every tool runs entirely in your browser against a hosted backend — no LaTeX installation, account, or sign-up needed.

If these save you time, you can leave a tip — it helps keep them free and online.
