Soulver: Write the question. Keep the working.
Soulver is a natural-language notepad calculator for arithmetic, units, currencies, dates, percentages, variables, subtotals, and business-day questions, with live answers beside editable plain text.
A calculation becomes reusable when the prose survives.
A calculation sheet where the explanation and answer stay together.
Soulver's answer column matters because it preserves both sides of the thought: the number and the sentence that produced it. That makes small financial, date, and conversion questions easier to check later than a calculator tape, without asking the user to build a spreadsheet.
