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, 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, and setup walks you through it. Your key stays in your browser — or skip it and use CHAT.
Pick the calculator from the browser's device list and start typing on it.
The calculator speaks one simple line protocol and does not care what is on the other end. Today that is your computer. Next it is a board small enough to live in the case with it.
The cable that came with the calculator, straight into your computer. This page does the thinking. Nothing to install.
A XIAO ESP32-S3 Sense on the link port with its own WiFi, its own battery and a camera. No computer anywhere.
You reach the bridge over Bluetooth once, from bridge setup, to give it a network and a key — after that it runs on its own. The camera is the interesting part: point it at a question in a book rather than typing an integral on a keypad.
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.
