About Jisuan
Jisuan — Calculate right where you type.
What Jisuan does
Jisuan is a macOS calculation tool for standard HTML text fields and web forms in Google Chrome. Enter an expression, invoke Jisuan, review a candidate and confirm insertion into the same field.
Supported scope
Support is limited to standard HTML text input that macOS accessibility can recognize in Google Chrome. Web spreadsheets, native desktop office applications and other input hosts are outside the product scope. Password, secure and read-only fields are refused.
Local calculations
Calculation inputs and results are processed on your Mac. Saved template definitions, defaults and personal constants can sync to your account. You choose when to insert a result and should review it before use.
Free and Pro
Free provides core calculations. Pro adds the features listed on the plans page. The current paid offer provides one year of Pro access with a one-time payment and no automatic renewal.
