lattedit: a free local-first browser LaTeX editor with a JSON API for agents
cneuralnetwork · x · 2026-11-11
lattedit is a free online LaTeX editor that runs local-first in your browser, showing source and compiled PDF side by side — no account or API key needed for the editor or the compile API.
Highlights:
- Supports pdfLaTeX, XeLaTeX, LuaLaTeX, BibTeX/Biber, images and bibliography files, with syntax highlighting, command completion, structured compile logs, and an accessible PDF preview
- Compilation runs in isolated short-lived workspaces; safe auxiliary state is reused and exact repeated builds skip the TeX engine
- Projects stay in the browser by default, export as plain ZIPs, and Overleaf ZIPs can be imported; sync is optional after sign-in
- Built for people and software agents: create papers, resumes, reports, theses or slide decks, diagnose LaTeX errors, or compile projects via a JSON API — handy for agents producing compiled documents
