GhostTeX

GhostTeX converts PDF documents and handwritten equations into clean, publication-ready LaTeX using on-device vision AI. No cloud processing — everything runs locally on your Mac with Apple Silicon.

GhostTeX can output .md with inline math — ready for Obsidian, Notion, Quarto, or any Markdown-based workflow

FULL DOCUMENT MODE Drop a PDF and convert entire pages to LaTeX in one click. GhostTeX preserves equations, tables, references, and document structure. Choose between Raw Markdown or fully formatted LaTeX output with automatic equation numbering and labeling.

EQUATION CAPTURE MODE Open any PDF, draw a rectangle around an equation, and instantly extract it as LaTeX. Capture multiple equations from the same document — each one is appended automatically. Works with dropped PNG and JPEG images too.

POWERED BY ON-DEVICE AI GhostTeX runs Qwen3-VL, a state-of-the-art vision language model, entirely on your Mac. Your documents never leave your computer. No internet required after the initial one-time model download.

BUILT FOR RESEARCHERS
• Scientific paper mode with full structure preservation
• Automatic equation numbering and \label generation
• Supports complex tensor notation, Greek symbols, and multi-line equations
• Chat with AI to refine or correct extracted LaTeX — select any region, including a spot flagged by a build error, and ask the AI to fix it

LOCAL LATEX COMPILATION GhostTeX now compiles .tex files using a local LaTeX engine powered by Tectonic. Build your document and preview the resulting PDF instantly inside the app. Compilation runs entirely on your Mac, with no cloud service required. If a build reports an error, just select the highlighted region in the editor and ask the AI chat to fix it — no LaTeX debugging required.

Copy LaTeX to clipboard or save as .tex file • Adjustable image resolution (1024 / 1600 / 2048 px) for quality vs. speed
