Any AI that accepts images. ChatGPT, Claude, Gemini, Cursor, Windsurf—if it has vision capabilities, it works. Just export your annotated screenshot and paste it into your AI chat.
Regular screenshots require you to type out "see that button on the left, below the header, next to the icon..." With numbered annotations, you just say "fix the issue at #1" or "change #2 to blue." Your AI sees exactly what you mean.
Nope. The free version gives you 5 annotated screenshots per day, which is plenty for most developers. Upgrade to Pro for unlimited screenshots and watermark-free exports.
