Radical Pie

Professional Equation Editor

Coming Soon

Radical Pie is a professional equation editing application for Windows 10/11 currently in development by Eric Lengyel. A beta test is planned for this spring, and the final release is expected in summer 2025.

Here’s an example of a short math-heavy paper written in Microsoft Word with Radical Pie: Relativistic Quaternions.

Purpose

The goal of Radical Pie is to produce mathematical typography of the highest possible quality. It’s suitable for use in the most demanding technical documents ranging from conference papers to large textbooks. It is also designed to be a perfect solution for putting equations in slide presentations and YouTube videos.

Radical Pie is not a word processor. It just handles the math. It is seamlessly integrated with Microsoft Word, and it produces vector output that can be transferred to most other applications. There are no compatibility problems when equations are transferred to different computers because everything is outlined, and the original fonts are thus not needed.

Radical Pie will be sold under traditional software licensing terms. You purchase it once, and the version you bought works forever. No subscriptions. No signing in. No connecting to a server on the internet.
