EqualX

EqualX is a graphical LaTeX equation editor for writing and editing individual equations rather than full documents. It combines a templates toolbar of common equations with a grouped symbols toolbar that offers tooltips and click-to-insert symbols, alongside code completion and syntax highlighting to support typing TeX or LaTeX directly.

Features include foreground and background styling, a library for bookmarked equations with titles, descriptions, folders, and search, plus a history of created equations. The editor supports LaTeX error reporting through a parser that locates problems, with the full log available in the LaTeX Output view. Export covers common file types, including SVG, and exported files can be loaded back into the editor.

EqualX is intended for users who need to produce equations for papers or presentations, while full documents, articles, or presentations are better handled by a full LaTeX editor. The pages describe it as a downloadable application for your system, without specifying plans, trials, or seat-based packaging.
