Show Claude What's Broken Instead of Typing It Out
A free, open-source Mac app that records your screen while you talk and draw on it, then hands Claude a page of marked-up snapshots and a transcript. How to install it, how to use it with Claude Code, a prompt, and the catch
Describing a visual bug in words is slow, and Claude still has to guess which button, which row or which pixel you mean. Scrawl is a free, open-source Mac app (691 stars on GitHub, MIT) built for exactly this: you show the problem instead of describing it. You record your screen, talk, and draw right on it, and Claude gets a page of numbered snapshots with your marks on them plus a transcript of what you said, lined up in time.
Here's how to install it, how to use it with Claude Code, a prompt to start with, and the catch.
