lattedit: A Local-First Browser LaTeX Editor With a Built-In MCP
cneuralnetwork · x · 2026-11-16
User @thegooddevill recommends lattedit.xyz, calling its MCP "flawless" and regretting weeks of settling for Overleaf.
lattedit is a free online LaTeX editor that shows source and compiled PDF side by side. Projects stay in the browser by default, export as ordinary ZIP archives, and sync only optionally after sign-in. It supports pdfLaTeX, XeLaTeX, LuaLaTeX, BibTeX, Biber, images, bibliography files, syntax highlighting, command completion, structured compile logs and an accessible PDF preview. Compilation runs in isolated short-lived workspaces, reuses safe auxiliary state, and skips the TeX engine on an exact repeated build.
It is built for both people and software agents: write papers, resumes, reports, theses or slide decks; import an Overleaf ZIP; diagnose LaTeX errors; or compile via a JSON API. No account or API key is needed for the editor or compile API.
