What makes this different

Most online LaTeX editors are just compilers. This one drafts your paper too.

Researchers searching for an online LaTeX editor usually want three things: no local install, reliable compilation, and something that helps with the actual writing. The first two are table stakes. resea.org adds the third.

Compile without installing TeX Live or MiKTeX

The most painful part of setting up LaTeX locally is the distribution install. resea.org removes that entirely. Open the IDE in your browser and compile a full document with packages, figures, and BibTeX in one click.

No TeX distribution install required
Supports common packages: geometry, amsmath, hyperref, natbib
Compiles multi-file projects with \include and \input

BibTeX and citation management online

Upload your .bib file or build your bibliography inside the IDE. Citation-aware AI drafting means the references you add stay connected to the text you generate.

BibTeX file upload and inline editing
\cite{} autocomplete from your bibliography
AI drafting that references your uploaded papers

AI writes your first draft inside the editor

Going from notes and references to a working LaTeX document is the hardest part. resea.org's AI drafting generates structured sections — introduction, related work, methods — from your research context.

Generate thesis, article, and report sections
Academic writing style, not generic copy
Edit the draft inside the same LaTeX environment

Why researchers switch from offline LaTeX

Setup friction and no AI assistance

Installing and maintaining a local LaTeX distribution (TeX Live, MiKTeX) takes hours and breaks on OS updates. Offline editors also have no access to AI drafting or citation-aware writing tools without additional plugins and API configurations.

Multi-gigabyte distribution installs
Package conflicts and TeX Live update issues
No built-in AI drafting or research context

What a good online LaTeX editor provides

Open the browser, start writing

The ideal online LaTeX editor eliminates setup entirely and then goes further by bringing the research tools into the same environment so the writing workflow does not fragment across apps.

Zero-install compilation in the browser
BibTeX, PDF export, and collaboration built in
AI-assisted drafting that understands academic documents
