Formudrag

Read full description

Formudrag helps you build, edit, and organize math formulae with drag-and-drop LaTeX tools. Start from built-in templates or your own saved components, replace exact structures directly, and keep a scratchpad nearby while refining the main formula. Use it for class notes, assignments, research drafts, teaching materials, and other academic workflows that need faster formula editing without losing structural control.
