Points and comments are a snapshot, not live.
A WYSIWYG editor for TikZ diagrams that preserves existing LaTeX code formatting.
TikZ Editor v0.4.0 is a free, MIT-licensed open-source tool for editing TikZ figures in LaTeX. It lets users drag elements to update coordinates instantly, add paths, nodes, rectangles, and circles, and edit source with syntax highlighting, diagnostics, and inline color pickers. The app supports snapping, multi-selection, grouping via TikZ scopes, and opening full .tex files with multiple figures via thumbnail previews. It parses frequent TikZ commands to preserve indentation and line breaks, uses MathJax for text/math, and includes converters for SVG, Ipe, and PPTX. A desktop version adds AI assistance via OpenAI Codex. Built over three months by Dominik Peters using GPT-5 series and Claude, using TypeScript and Tauri.
What commenters are saying
Commenters are overwhelmingly positive, calling it long overdue and thanking the author for making it open source. Several note the key feature is editing old TikZ without generating 'soup.' Requests include support for pgfplots, cetz (Typst), and relative positioning. One user reports a grid rendering bug on Linux Mint. The name TikZ is explained: 'TikZ ist kein Zeichenprogramm' (TikZ is not a drawing program).
