Online equation editor

The tool is a free, web-based equation editor that enables users to input, format, and render mathematical expressions with high fidelity. It supports standard LaTeX math syntax and an internal equation notation, with modes for inline notation and display blocks. Target users include students drafting problem sets, educators preparing notes, researchers documenting formulas, and developers embedding math into technical content. The editor emphasizes accuracy, export flexibility, and immediate feedback to reduce manual formatting time.
Conceptually, input is parsed into a structured expression, mapped to glyphs via a symbol table, and laid out by a typography engine. The renderer outputs vector or bitmap formats such as SVG or PNG, preserving spacing and alignment. Live rendering updates as the user types, and options exist for switching between inline and display formats, selecting export format, and applying templates for common constructs like fractions, roots, and sums.
Its unique value is being freely accessible with no signup, providing LaTeX compatibility and robust export options. It supports a symbol palette, templates for common math patterns, and multi-equation support to streamline worksheets and documentation. Use cases include assignment creation, lecture slide preparation, research notes annotation, and algorithm documentation. Core differentiators are real-time rendering quality, broad export support, and a lightweight, domain-focused feature set.
