Sumico

A calculator you type to, in plain English

Sumico has no keypad. You type a question the way you would write it, and the answer appears next to the line. Percentages, units, currencies and powers all work the same way.

What the video shows

A giant line types itself: 20% of 450, and the answer, 90, appears. The camera moves into the app, where more lines answer as they are typed: $100 in EUR, 5 ft 11 inches in cm, the days until December 25, 2 to the power of 10, the square root of 144, 350 °F in °C and 1.5M divided by 12. No buttons and no equals sign. The phone then turns through the app’s themes.

Questions

Is there an equals sign?

No. The answer appears as you type. To use a result later, give it a name, like price = $19.

Does Sumico use AI?

No. Every answer comes from Sumico’s own calculation engine on your device.

What if a line does not calculate?

The line is marked, and the message says why: an unknown unit, an unknown name or a missing bracket.
