TextMan has the same feature as TextSniper but seems lighter, adding an option for you in copying any text on the screen the easiest.
Select Screen Region
Select any text on your screen by drawing a rectangle to start OCR detection*. Use it with web sites, PDFs, and images.
*scanned text can be English, French, Italian, German, Spanish, Portuguese, and Chinese (both simplified and traditional)
Find all detected text in your clipboard ready to paste it into every text field.
Don’t Repeat Yourself
Your scanned texts are collected in a workflow list and can be restored to your clipboard.
