In 2005, we, Zac Cohan and Nik Youdale, created a new kind of calculator interface called Soulver.

Over the past ~20 years, we have continually enhanced Soulver by:
• Allowing the use of words alongside numbers for added context.
• Adding many natural language functions to ease problem-solving.
• Incorporating variables and syntax coloring inspired by programming languages.
• Implementing line references borrowed from spreadsheets.

Soulver's UI has inspired many other products across all major platforms.

As of 2024, we still believe there are innovations to be discovered in our quest to perfect the notepad calculator.

If you have found Soulver (or its clones) indispensable, please consider supporting our explorations. By sponsoring us, you are directly contributing to the discovery and development of novel features in the genre of notepad calculators.
