Capture Image
How this Rule works
Text Typed starts a full-screen capture. Convert Image produces PNG, and Copy File copies the result to the selected folder, using a numbered name if needed. There is no Condition.
Configure and try it
Choose an uncommon typed phrase and a writable destination folder. Grant Accessibility and Screen Recording permissions, enable the Rule, type the phrase in a normal text field, and check the PNG in the destination.
Requirements and limits
Text Typed and Convert Image require Rulr Pro. The sample captures the full screen; it does not select a region or extract text. Change the capture target if you need a different capture.
