Plug a TI-84 Plus CE into your computer and it becomes a chat client, an AI assistant and a maths solver that shows its working. Nothing to install, no server to run.
Ask anything and get an answer back on the calculator screen, kept short enough to actually read.
Type an equation the way you'd write it — every key gives what's printed on it — and get worked steps, not just an answer.
Message between the calculator and the browser. Rooms and multiplayer games are coming next.
The page talks to your calculator directly — over USB today, over Bluetooth or Wi-Fi once the bridge board is done — and to your chosen AI provider over HTTPS. There is no backend in between, which is why there is nothing to install and nothing to trust us with.
Send GPT, MATH and CHAT to your calculator with TI Connect CE. One time only.
Groq, OpenRouter and Google all have free tiers. Your key stays in your browser.
Pick the calculator from the browser's device list and start typing on it.
The calculator speaks one simple line protocol, so it does not care what carries it. USB works today with nothing but the cable in the box.
The cable that came with the calculator, straight into your computer. Web Serial does the rest.
A coin-sized ESP32 board on the link port, paired straight to the browser. No wire to the computer at all.
The same board on your network instead, so the calculator can reach the internet with no computer involved.
The console already speaks all three — the hardware is what is still being built.
All of it is free, and most of it you probably already have.
Send these across with TI Connect CE, then launch them through arTIfiCE or
Cesium — they're compiled programs, so they won't run from the
[prgm] menu on OS 5.5 and later.
