lattedit launches free local-first browser LaTeX editor with MCP support for coding agents

cneuralnetwork · x · 2026-11-11

lattedit is a free, local-first LaTeX editor in the browser: source and compiled PDF side by side, projects stay in-browser by default, exportable as plain ZIP archives, optional sync after sign-in. It supports pdfLaTeX, XeLaTeX, LuaLaTeX, BibTeX/Biber, images, bibliographies, syntax highlighting, command completion, structured compile logs, and an accessible PDF preview; compilation runs in isolated short-lived workspaces with safe auxiliary-state reuse.

It is designed for both humans and agents: import an Overleaf ZIP, diagnose LaTeX errors, or compile via a JSON API — no account or API key required — with MCP support for Claude Code, Codex, and other coding tools.
