Why it matters #
Lattice gives researchers a local alternative to cloud AI writing workspaces: files stay in a Git-friendly folder, Overleaf co-authors need no new tool, and the coding agent remains the user's own Claude Code, Codex or Cursor account. That model keeps agent choice and costs outside the editor.
Leonardo introduced Lattice on November 6th, 2026, as a local-first LaTeX workspace for macOS. Leonardo (@leoliuym), the developer who says he built Lattice, wrote on X that a paper involves more than a .tex file. "I wanted it all in one app, so I built it," he wrote.
