Build Software While Doing Real Work
The right software isn't getting made because the right people aren't making it, yet.
Requirements
Free for individuals. No programming experience needed. Just modern Excel Desktop running Windows.
What The Addin Is
The Excel Addin is a single .XLAM file under 3MB. Whoa Systems never collects your workbook data or code.
How it Works
The Addin breaks from traditional architecture by putting all software layers in a single Excel
workbook—the application, the data store, and the codebase.
You organize your work into
models made of fields; the Addin wires the background code automatically. You focus on what your
program does. The Addin handles how it runs.
Or let AI do the building. The Addin's agent harness
gives ChatGPT, Claude or any AI a set of tools to work inside your workbook.
