Questions
What is it?+
A regular scientific calculator in a Casio fx-991ES case, with a camera and WiFi inside. Point it at a problem, press a key, and the AI's answer comes back on its own screen. No phone and no app.
There are two processors inside. One runs the calculator. The other wakes up only for an AI request and is off the rest of the time, so the battery lasts.

It's a thank-you, not an order: it doesn't buy a calculator, doesn't change your place on the waitlist and isn't refundable. Want a calculator? Leave your email on the Buy page.
