A Micro Keyboard for ChatGPT and Codex
A micro keyboard is a small second keyboard that sits beside your main one and does nothing but fire the actions you repeat. People search for a ChatGPT or Codex version of this for a good reason: the typing is being done by the model now, and the human part of the job has shrunk to a handful of decisions. Send. Accept. Reject. Run it again. This page explains what such a device can honestly do, and which of ours fits.
Is there an official ChatGPT keyboard?
No. There is no keyboard sold by the makers of ChatGPT, and nothing we sell talks to ChatGPT or Codex through an interface of its own. Whatever you buy for this, ours included, is an ordinary keyboard as far as your computer is concerned. It sends key presses. Your operating system, your browser and your terminal decide what those presses mean.
That sounds like a limitation, and it is the reason the approach works. A device that only sends key presses needs no permission from anyone, does not stop working when an app changes its interface, and behaves the same on the day you move from Codex to Claude Code or Cursor.
What would I map the keys to?
Watch yourself for one working session before you decide. Almost everyone lands on the same short list: submit the prompt, accept the suggestion, reject it, clear the input, repeat the last command, and jump back to the terminal. In the Codex CLI those are keys you are already pressing. In ChatGPT in a browser they are mostly Enter, Escape and whatever your browser uses to change tab. A micro keyboard does not add an action. It moves the ones you have somewhere your hand can find without looking.
A knob earns its place here more than an extra key does, because scrolling back through a long answer is the other thing you do constantly, and a knob does it with one finger.
Which one should I buy?
If you want the smallest thing that is still a real keyboard, the EM Mini Pad at $75 is five keys and a knurled knob in a heavy anodised aluminium block, wired over USB-C or connected over Bluetooth. If you want a key for each step of a review loop with knobs on top, the KM16 Macropad at $119 gives you sixteen keycaps in a four by four grid, one large knob and two small ones. If your list of repeated actions honestly has two items on it, buy neither: two large buttons at $29 will cover it, and we would rather say so.
Do I have to configure it myself?
Yes. You choose what each key sends, and the first evening involves a settings screen rather than a moment of magic. We have not tested every device against every version of macOS and Windows, and we will say that plainly instead of guessing on your behalf. What is true of the whole category is that these present themselves to a computer as keyboards, which is the least demanding thing a peripheral can ask to be. Where the details differ, they are on the product page, and if the page does not answer your question, ask us.
What will it not do?
It will not know when your agent has finished thinking. It will not read your screen or approve anything for you. It will not make a model better at writing code. It removes hand travel and nothing else. If hand travel is not what is slowing you down, keep your money.
If you are still weighing a five key pad against something wider, our note on what a macropad is actually for in programming is the unglamorous version of that decision.
