As a researcher, your time belongs to breakthroughs—not wrestling with LaTeX boilerplate, resolving package conflicts, or the endless copy-paste loop between Overleaf and ChatGPT.
LMMs-Lab Writer is a local-first, AI-native LaTeX editor. Your files remain secure on your machine. AI agents assist with editing directly. Compile, review, and publish—all within a single, unified environment.
Say goodbye to hour-long TeX Live installations. LMMs-Lab Writer automatically detects and installs a lightweight LaTeX distribution. If a package is missing, it’s installed on the fly during compilation. Zero manual configuration required—just open the app and start writing.
Supports TinyTeX, MiKTeX, MacTeX, and TeX Live—with streamlined, one-click management.
Write effortlessly in English, Chinese, Japanese, Korean, Arabic, or any other language. XeLaTeX and LuaLaTeX are supported out of the box with full Unicode and system font compatibility. CJK documents work instantly with ctex, xeCJK, and other multilingual packages—no extra setup needed.
The built-in OpenCode panel brings AI directly into your editing experience:
You: "Add a related work section comparing our method to LoRA and QLoRA"
Agent: *writes directly to main.tex in real-time*
You: *hit compile* Done.
- Chat with AI, attach files, and manage context seamlessly
- AI analyzes your entire project for deep context awareness
- Edits are reflected in the editor in real-time
- Compatible with any model—Claude, GPT, Gemini, DeepSeek, or local LLMs
It also pairs perfectly with Claude Code, Cursor, Codex CLI, Aider, and other tools. The editor monitors your project directory, syncing external changes instantly.
Git isn't just an add-on; it's deeply integrated into the sidebar:
- Stage, commit, diff, push, pull—entirely via the UI
- AI-generated commit messages based on your staged changes
- Side-by-side diff viewer for reviewing AI suggestions before committing
- One-click GitHub publishing—create and push repositories without touching the terminal
- Seamless GitHub CLI integration for effortless authentication
Stop paying premium prices for basic Git sync. Here, version control is free, powerful, and built-in.
