Description
Jisuan is a macOS app that calculates right inside supported Chrome text fields. Type an expression, press ⌘⌥=, preview the result, and confirm to write it back. Handle amounts, tax, dates, and ratios without switching to a calculator. Calculations run locally on your Mac with Decimal precision. Core calculations are free; Pro adds financial expressions. Currently in public beta for Google Chrome on macOS.

Could you build this?
Partial Parsing math expressions is trivial, but hooking global keystrokes and reading/replacing text inline inside Chrome text fields requires deep macOS Accessibility and IPC integration.
What it would actually take: The application requires native macOS code (Swift/Objective-C) utilizing the macOS Accessibility API (`AXUIElementCopyAttributeValue`, `AXUIElementSetAttributeValue`) to monitor focused input controls in third-party browsers. It must handle non-standard web views, evaluate mathematical and unit expressions with arbitrary-precision decimal libraries, and manage system accessibility permissions. Handling edge cases across Chrome's multi-process rendering tree requires deep native desktop systems expertise.
