Radical Pie review
A capable Windows equation editor with Office embedding and a one-time $60 license.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Radical Pie is a standalone WYSIWYG equation editor for Windows 10/11. It is designed for people creating mathematical notation in technical documents, presentations, videos, and diagrams, with direct Microsoft Word and PowerPoint integration. Users can work in math, chemistry, or plain-text modes, assemble equations from structures and symbols, and attach drawing annotations such as highlights, boxes, and arrows. Its fit is strongest for solo users and small teams working primarily in Microsoft Office.
The published pricing plan is straightforward: a Single-user license costs $60 USD as a one-time purchase. It provides a perpetual license, and minor updates are included at no additional cost. A fully functional 30-day trial is available before purchase. There are no recurring tiers to compare, so the main commercial question is whether a one-time desktop license fits your workflow and whether one user needs the software at a time.
Office integration is the product's central strength. Radical Pie embeds live equation objects in Word and PowerPoint and converts Microsoft Office Math equations into its own format. For downstream publishing and accessibility workflows, it exports SVG, PDF, and EMF, generates LaTeX code, and exports MathML for alternative text and clipboard content. The trade-off is a narrow platform scope: the documented release is Windows desktop software, while a macOS version is described as in development. There is no web editor, handwriting input, or OCR-to-equation capability. Choose Radical Pie when Windows-based Office editing and export control matter most; choose another tool if browser access or macOS support is essential.
