One of the better recent features in macOS is Live Text, which lets you copy text from images on your Mac in Preview, Quick Look, or Safari. It’s a bit of magic, to be honest: any text in an image can be highlighted and copied, just like text on a website or in a document. The problem: this feature only works for image files, not videos, and you can’t use it to copy text from a presentation being shared in a meeting unless you take a screenshot and extract the text from that.
macOS Shortcuts: Capture Text from Your Screen
Meet TRex, a free application for Mac that speeds up this workaround. It works similarly to Text Extractor for Windows: Select the area of your screen that contains the text you want, whether that text is in an image, a video, or a presentation. All of the text in the area of your screen you select will be instantly converted to text and copied to your clipboard. This functionality comes at a price: TRex costs $8 from the Mac App Store or is free if you download it from Github.
After installation, you’ll be given a quick tutorial on how the app works, and its icon will appear in your menu bar. You can activate the app from there, or set optional keyboard shortcuts in the settings. The app itself uses the same crosshairs you see when taking a screenshot on your Mac, but instead of taking a screenshot, the app searches for text it can recognize using optical character recognition (OCR). That text is then copied directly to the clipboard.
Only a handful of languages are currently supported: English, German, Italian, French, Spanish, Portuguese, and Chinese. The application can automatically detect the language of the text you are copying if you want, but it performs slightly better if you choose a default language in the settings.
