Typing Calculator w/ ChatGPT (WiFi Enabled)

Please read the Purchase Disclaimer before purchasing to understand important information including limitations, setup requirements, and sales policies.

The Typing Calculator is a custom built device designed to send typed questions to GPT-5.4 and receive full worked responses directly on the calculator. This version is extremely discreet and designed for situations where you are heavily proctored.

You type your question using the calculator’s ABC keyboard layout. Once sent, the calculator connects through WiFi and returns a response containing steps, explanations, and a final checked answer. Response time typically ranges between 1 and 60 seconds.

After purchasing you will receive a setup tutorial through a QR code inside your package. Please watch the tutorial carefully before using the device. You then connect the calculator to your phone hotspot or any WiFi network that does not require a browser sign in page.

Battery life is approximately 10 hours when using 1.2V AAA 1100 mAh high capacity NiMH rechargeable batteries. I provide a link to the recommended batteries in the YouTube tutorial description you receive after purchasing. Using different batteries may result in different battery life. All units are used calculators that are fully tested before shipping.
