AI Mathing at the Speed of Voice

Calculator Star uses voice to help you solve complex everyday math questions in a matter of seconds. I believe that getting an answer shouldn’t require navigating complex menus or typing out long equations. Whether you are checking homework, comparing prices at the grocery store, or figuring out a tip, just ask.





Hi PH community, I am a product designer and entrepreneur based in the Bay Area (co-founder of Glow, previously Google and Slide).
I initially created this app for my daughter to help double check her math homework (she's in the third grade). Then I found that her classmates’ parents also wanted something like this, so I decided to polish it up and release it into the wild.
Data science is what I have always loved, and I do see a world where Calculator Star can evolve into something much bigger in the future. Because I believe there is a need for a truly intelligent computational engine. One that understands context, nuance, and language just as well as it handles raw numbers. Perhaps the aspirational goal is to build the world’s smartest calculator, capable of solving any math or physics problem you can voice. But for now, it's just day 1.
Have fun and DM me on X @kho to let me know how I can improve it!
Love the story behind this - building something for your daughter is the best motivation! The voice-first approach is brilliant for everyday situations. I can see myself using this while cooking or checking receipts at the store. Does it work offline, or does it need an internet connection for the AI processing?
@easytoolsdev Thanks for the kind words! Basic calculator functions work offline. Voice AI features require an internet connection for processing.
