Chaser is a macos utility you can use to capture more than a screenshot. Screenshots are good tools to show your agents what you're seeing, but there's far more that goes on behind the scenes - the layout, button states, mapping of objects on your application, things that are out of your line of sight - all help make the context better. Chaser uses macos accessibility features to help you capture all that and more. No LLM, 100% local.
This was inspired by Codex appshots. I really loved it so built a version that lives outside codex, also with history and the ability to annotate before sharing.
