The Theory
The gap between thinking and typing is where good ideas go to die. You have a clear thought—a fix, an approach, a question—but by the time you've context-switched to your keyboard, half the nuance is gone.
Field Theory exists to close that gap. Speak your thought. Get it transcribed locally. Paste it into your AI coding tool. Done.
Why Voice?
You think in continuous streams. Typing forces you to think in discrete chunks. Voice lets you externalize thought at the speed you actually think— complete with the "wait, actually" moments that often contain the real insight.
For AI prompting specifically, voice is powerful because rambling is fine. You can dump context, explain the problem, mention constraints, and let the AI sort through it. The prompt doesn't need to be polished. It needs to be complete.
Why Local?
Your voice contains everything. Work conversations, passwords spoken aloud, half-formed ideas, complaints about your coworkers. None of that should live on someone else's server.
Modern Macs can run Whisper locally at near-realtime speed. There's no technical reason to send your audio to the cloud anymore. So we don't.
Why a Clipboard?
The clipboard is the universal interface. Every app knows how to paste. Instead of building integrations with a dozen tools, we put your transcriptions where they're already useful: in your clipboard history, ready to paste anywhere.
This also means your voice notes, screenshots, and copied text all live in one timeline. One searchable, stackable, organized timeline.
Why Multi-Modal?
The best AI prompts aren't just text. They're text plus a screenshot of the error, plus the code you're looking at, plus the context of what you tried. Field Theory lets you stack all of these together into a single prompt.
Our vision model describes your screenshots automatically, so even the images become searchable text. "Find that screenshot of the login form" actually works.
The Name
Field Theory in physics describes how forces propagate through space. Our Field Theory describes how thoughts propagate through your tools— from your mind, through your voice, into text, into AI, into code.
Also, we just liked the name.
