Everything you need to write LaTeX faster

A complete editor with an AI that actually does the work — not just autocomplete.

Native AI Agent

Type an idea like "create a document about Jakarta" or "fix the literature review in chapter 2" — the AI autonomously creates, edits, and deletes files in your project. Powered by opencode.

📄

Live LaTeX Preview

Compile with a click and see your PDF instantly. Scrollable, zoomable preview for both PDF and image files, powered by TeX Live & latexmk.

🔌

Bring Your Own Model

Start free with the bundled model — or plug in your own OpenAI, Google Gemini, Anthropic, or any custom OpenAI-compatible endpoint. Test the connection right in the app.

Professional Editor

A Monaco-powered editor with a resizable four-panel layout — file explorer, editor, preview, and AI chat. Fast, clean, and built for real work.

Use any AI provider you like

Free by default, no account required. Already subscribed to OpenAI, Gemini, or Anthropic? Just paste your API key, pick a model, and verify the connection with one click.
