What is LetX?

LetX is a real-time collaborative LaTeX editor built for research teams, academics and students. Multiple authors edit the same document at once with no merge conflicts, using Yjs CRDT sync with live cursor presence.

Key features: • Free unlimited collaborators on every plan, including the free one • 1,000+ ready templates: IEEE, ACM, Springer, Nature, arXiv, university theses, CVs and Beamer decks • Compiles in a few seconds on the full TeX Live 2024, using pdfLaTeX, XeLaTeX or LuaLaTeX • Lexi, a built-in AI assistant that edits the document, runs the real compiler, reads the latexmk log and fixes the line that failed • A hosted MCP server on paid plans, so Claude and ChatGPT can search templates, edit projects and compile to PDF directly • Bidirectional SyncTeX between source and PDF • Multi-file projects with a drag-and-drop file tree, image uploads and BibTeX • Version history, and two-way GitHub sync on Pro • ZIP import and export for migrating from Overleaf • Roles (Owner, Editor, Viewer), email invites and share links • CodeMirror 6 editor with syntax highlighting, autocomplete and split-pane preview • Team plan for labs, small groups and classes of 2 to 50 people: $20 per seat a month, one bill • Your documents are never used to train AI models

Runs in any browser on Mac, Windows and Linux. Nothing to install.
