TikZ Editor is a new open-source tool that brings visual editing to TikZ, the popular LaTeX package for creating figures in academic papers. The editor runs on web and desktop platforms, letting users drag and resize elements while maintaining live synchronization between visual and code views. This eliminates the tedious cycle of manually adjusting coordinates and recompiling to check results.

Most WYSIWYG editors treat source code and visual output as separate modes, but TikZ Editor keeps both views editable and in sync simultaneously. The implementation parses TikZ code and tracks the exact source location of each object, allowing precise modifications to coordinate values without disrupting formatting like line breaks or indentation.

Building this required reimplementing substantial portions of TikZ itself—a task the developer notes would be impossibly tedious without AI assistance. Codex handled nearly all the coding, enabling features like SVG, PowerPoint, and Ipe format converters that weren't originally planned.

The project demonstrates how coding agents can tackle previously unfeasible projects by absorbing the mechanical complexity. For academics who spend hours fine-tuning figure coordinates, this tool could significantly streamline their workflow while preserving the precision that makes TikZ valuable.
