Field Theory

Overview

Field Theory is a macOS productivity tool for developers that enhances how you capture and share context with AI assistants. It combines local voice transcription, screenshot annotation, and portable markdown commands into a unified clipboard-based workflow. Speak with voice commands injected mid-speech, annotate screenshots with circles, arrows, and freehand sketches, then stack multiple items into a single prompt. Works with any AI tool that accepts paste input — ChatGPT, Claude, Cursor, Copilot, Gemini, and more. All core features run locally and offline.
