Drop a batch of statics. Drag a box over any wrong text — a digit on the tin, a smudged word — type what it should say, and it repaints just those pixels in the matching font. Everything else in the ad is copied through untouched, so product copy can't smudge. Runs in your browser; nothing uploads.
Nothing marked yet. Scroll to zoom (or hit “Find small print”), then drag a rough box over the wrong text — it snaps to the letters.
