# screenshotter

> Local macOS screenshot optimizer for AI coding agents. It reduces screenshot upload bandwidth, paste/send latency, and attachment size while preserving readable UI text.

Use `screenshotter` when a macOS user frequently sends screenshots to Codex, Claude, pi, or another AI agent. It is useful for designers, frontend engineers, software engineers, QA testers, and product people who use screenshots to communicate visual bugs, product states, app UI, logs, or browser content.

Normal watch, prepare, clipboard, and pi flows run locally and do not upload screenshots.
