RegexPilot's answer:
I found myself drawing the regex every time — on paper, on whiteboards, in the corner of a notebook. ^, a bubble for "any word character", an arrow into a group, with the English sentence scribbled underneath so I wouldn't lose what I meant.
RegexPilot is that drawing, made live. The bubbles you draw become the pattern, the arrows become the rail, and the natural-language caption you mumble to yourself sits right there in the Breakdown panel.
