DuoLanMath

DuoLanMath is a modern Windows OLE equation editor for Microsoft Word, PowerPoint, WPS Writer, and WPS Presentation. It is designed as a faster, more stable, and easier-to-use alternative to MathType for creating professional, fully editable equations directly inside Office documents. DuoLanMath integrates into the Office ribbon through a C# and Microsoft VSTO add-in. It does not rely on document-embedded VBA macros, so it does not trigger macro security warnings or macro-related errors. The editor runs at the add-in level and keeps formula editing separate from the document's macro environment. With DuoLanMath, users can create equations visually, insert inline or display equations, and convert LaTeX into editable OLE equation objects in batches. Equations remain editable after insertion: simply double-click an equation object in the document to reopen and modify it. Formula source can also be restored when needed, making revision workflows much easier than working with static equation images. Key features include: .Native support for Microsoft Word, PowerPoint, WPS Writer, and WPS Presentation on Windows .Editable OLE equation objects instead of flattened images .Batch conversion from LaTeX to editable equations .Bidirectional conversion between LaTeX and DuoLanMath equations .Bidirectional conversion between Word OMath and DuoLanMath equations in Microsoft Word .Vector-based EMF output for crisp equations at any zoom level .Visual equation editing, LaTeX input, templates, matrix tools, font controls, colors, and size settings .Support for Chinese text in LaTeX equations .One-click Office ribbon integration through a standardized COM add-in .C#-based managed architecture designed to reduce common native-memory risks and improve reliability DuoLanMath is built for students, researchers, teachers, engineers, technical writers, and office professionals who need to write, convert, edit, and reuse equations in Windows Office documents without breaking their workflow.
