Stop the copy-paste loop. ScreenTranslate is a lightweight macOS utility for instant on-screen translation. Inspired by ScreenHint’s seamless capture, I built this to solve a personal pain: translating uncopyable text in images, video frames, and locked PDFs. 1)Drag-to-Translate: Instant results by dragging over any area. 2)Stay in Flow: No more switching to Google Translate tabs. 3) Privacy-First: Native macOS experience with no data collection.
