Before GhostMark, I kept writing things like move the button near the top-right below the banner and hoping the agent understood the same element I meant.
For a one-arrow change, text feels like the wrong interface. It gets worse when the feedback is really a user flow rather than a single location.
Paste a screenshot in Claude Code, draw the arrows, circles, or user flow you mean, then press Enter. GhostMark sends the marked image back to the prompt. Free, local, open-source, and Apple-notarized for macOS.
You talk, Sumi types — but not what you actually said. It cleans up filler words and grammar, then adjusts tone for whatever app you're in. Gmail gets a professional version, Slack gets something short. Meeting mode records calls in the background. Edit by voice: select text, say what to change. 100+ languages. Runs on your machine. Free, GPLv3. macOS + Windows.
