Hey Product Hunt! I’m Dane, maker of Casso. I kept hitting the same snag with coding agents: I could see exactly what was wrong in the UI, but I still had to translate it into a vague prompt. Casso lets you freeze any app, box the relevant areas, add notes, then paste the visual context into the agent you already use. It works with any agent, keeps screenshots and annotations local, and auto-pastes directly into your terminal. I built it to replace “move that thing slightly left” with a clear visual handoff. I’d love to hear what UI feedback you keep repeating to your coding agent.
