LaTeX Snip

Drag-select any math on screen → LaTeX, instantly. Bring your own API key.

LaTeX Snip lets you capture any mathematical expression on your screen and convert it to LaTeX in seconds. Simply click the icon (or press Ctrl+Shift+L), drag a box around an equation, and hit "Use this snip." The extension sends the image to your chosen AI provider and returns clean LaTeX — rendered as a live math preview so you can verify it before copying. Features: • Drag-select capture on any webpage, PDF, or image • Supports Claude (Anthropic), GPT-4o (OpenAI), and Gemini (Google) • Live KaTeX math preview before you copy • Raw LaTeX always visible alongside the preview • Draggable result panel • Fully client-side — no backend, no account, no tracking Bring your own API key: LaTeX Snip calls your chosen AI provider directly. Your key is stored only on your device and never shared with anyone. Whether you are writing a Latex document, interfacing with an LLM, etc., LaTeX Snip is ideal for students, researchers, and engineers working with papers, textbooks, or any technical content containing math.
