AI Error Detection

An agent that compiles with you

The online LaTeX compiler is not just a button. Ask Bibby Agent to compile, explain a cryptic log, insert a citation, or turn the paper into Beamer slides. It reads the same files the compiler uses.

  • Plain-language error explanations and one-click fixes
  • Citefind literature search into your .bib file
  • Paper review, posters, diagrams, and Word export from the same project
Compile this paper and fix any LaTeX errors

AI error detection, then a clean PDF

Watch Bibby read a log, explain the error, and patch the source. Then hit compile again. The same agent lives in the online LaTeX compiler.

  • Plain-language explanations for Missing $, undefined citations, and unmatched braces
  • One-click apply and recompile on TeX Live
  • Works with pdfLaTeX, XeLaTeX, and LuaLaTeX

The toroidal code emerges without supervision. Border cells may correct drift near the walls, a prediction we test in Section 5. Together these suggest path integration is learned, not built in.

Team collaboration

Collaborate while it compiles

Several people can edit the same .tex file. Live preview updates as the cloud compiler finishes. Stop emailing PDFs.

  • Invite collaborators to any project
  • Comments on the source
  • Cloud compile for everyone, not just the person with TeX Live

Compiler Features

Why Use Our Online LaTeX Compiler?

Everything you need to compile LaTeX documents, right in your browser

Instant Compilation

A project compiles .tex to PDF with pdfLaTeX, XeLaTeX, or LuaLaTeX. This page only shows a sample.

100% Browser-Based

No software installation required. Access the LaTeX compiler from any device with a web browser. pdfLaTeX, XeLaTeX, or LuaLaTeX.

AI Error Detection

Your AI co-author catches LaTeX mistakes before you compile, suggesting fixes and explaining errors. Bibby Agent can apply the patch and recompile.

All Packages Included

Projects compile with TeX Live, including amsmath, biblatex, and TikZ. A missing package shows up in the log.

Live Preview

Compile again after you edit. The PDF in the project is the result of that compile.

Export Anywhere

Download PDF, export to Word, or share a preview link. Your choice.

Citation search

Search PubMed, CrossRef, and Semantic Scholar. Insert BibTeX and \cite{} without leaving the compiler.

2,000+ templates

Start from NeurIPS, ICML, Nature, thesis, and Beamer templates with real thumbnails.

GitHub sync

Import a repo or Overleaf zip, compile on TeX Live, and keep version history in the project.

Figures in the workspace

Generate academic diagrams, check journal figure specs, and drop them into the project before you compile.

Slides and posters

Compile Beamer decks and conference posters from the same paper, then export PPTX or PDF.

Real-time collaboration

Several people can edit the same .tex file. Live preview updates as the cloud compiler finishes.

How to Compile LaTeX Online

1

Open a project

Sign up and paste your .tex file, or import a GitHub repo or a .zip.

2

Choose an engine

Compile with pdfLaTeX, XeLaTeX, or LuaLaTeX. If the log reports an error, read it and fix the line.

3

Download the PDF

Save the PDF from the project. You can also export a Word file from the same source.

LaTeX Compiler FAQ

Is the online LaTeX compiler free?

The sample on this page is free to watch. A free account compiles your own .tex project.

Does this page compile my file?

No. The demo shows a broken sample and a fix. Your paper compiles after you sign up and open a project.

Which engines can I use?

A project can compile with pdfLaTeX, XeLaTeX, or LuaLaTeX.

What packages are included?

Projects compile with TeX Live. Common packages such as amsmath, biblatex, and TikZ are available. A package missing from that build shows up as a log error.

Can the agent fix a compile error?

The demo on this page wraps a sum in math mode and compiles again. In a project, the agent can read the log and apply a fix. You still compile to confirm the PDF.

Can I export Word from the same project?

Yes. A project can compile to PDF and export a Word file.

You can do this on Bibby

Convert Handwriting to LaTeX in seconds

Turn handwritten notes, photos, PDFs, and Word docs into clean LaTeX, or export LaTeX to PDF and Word. Same editor, no install.
