Every chat window quietly charges you a tax: switch, paste, prompt, copy, paste back, fix. The interface is the product, and most AI writing tools got it backwards.
Watch someone use an AI chat tool to answer an email. They select the thread, copy it, switch to the chat tab, paste, type a prompt like “reply politely saying Thursday works,” wait, copy the answer, switch back, paste, then fix the formatting the paste broke. Six context switches to send three sentences.
The model did its job in two seconds. The other twenty seconds were interface. That ratio is the quiet scandal of the current AI writing landscape: we bolted a revolutionary text engine onto the oldest interaction pattern on the desktop, the clipboard.
The model takes two seconds. The interface takes twenty. Fix the twenty.
Extensions are not the answer either
The obvious patch is a browser extension, and it works, in the browser, on the sites the extension supports, until a redesign breaks the injection. Your Mac is bigger than your browser. The email that needs an answer is in Mail. The standup update is in Slack. The spec is in a native editor. Per-app plugins can never cover the surface area of an operating system.
The operating system, though, already knows where your cursor is. macOS exposes the focused field, the text around it, and the conversation on screen through its Accessibility APIs. An assistant built on that layer works in every app by construction, not by integration.
The field is the interface
That is the bet behind Cue. There is no chat window because the text field you are already in is a better one. You hold a key and say what you need, and the answer lands where your cursor is, formatted for the field it lands in. The clipboard never gets involved. Neither do you, except to read the draft and press send.
- No switching: the assistant comes to the field, not the reverse
- No prompt writing: the thread on screen is the context
- No paste cleanup: text is typed into the field like you typed it
Copy-paste AI made a generation of tools feel like translation booths. The next generation should feel like the computer finally learned to listen. One key. Just ask.
