84GPTCan you use AI on a TI-84 calculator?
Not by itself. AI models need thousands of times more memory than a TI-84 has, and the calculator can't reach the internet. A WiFi dongle like 84GPT sends your question to an AI service online and shows the answer, or the worked steps of a math problem, on the calculator's screen.
Why the calculator can't run AI
The TI-84 Plus CE has about 150 KB of working memory. Even small AI language models are many gigabytes. On top of that, the calculator has no WiFi, so it can't ask an AI service online either. Anything that claims to run AI entirely inside a TI-84 is a pre-written list of answers.
What people have built
Hobbyists have opened up their calculators and wired a tiny WiFi board inside, so the calculator can send questions to an AI service. It works, but it means taking the calculator apart and soldering, which isn't something to try on the calculator you need for class.
How it works with 84GPT
84GPT plugs into the calculator's USB port from the outside, so there's nothing to open. It gives the calculator two AI apps:
- AI Chat answers a question in a few clear sentences and remembers the conversation, so you can ask a follow-up.
- Math takes a problem you type with the calculator's own keys and shows the working in numbered steps, so you can see how it gets to the answer, not just the answer.
A free account includes 200 AI questions a month, with no subscription. Plus raises that to 2,000 if you use it a lot.
Tests and school rules
Use it to understand the steps, not to skip them. 84GPT can't run while the calculator is in Press-to-Test mode, and you should unplug the dongle before any test, because some tests don't allow anything attached to a calculator. Whether you can use it in class is up to your school, so check its rules first.
