For those on Windows, I find Capture2Text[0] to be a pretty great FOSS Screen OCR application: you press Win Q and select an area like the snipping tool would, simple as that.

It also has some other snipping modes, supports more than english, and has the option to, after the OCR, immediately show a popup window where you can fix what the OCR inevitably failed to properly recognize.

I recommend use alongside a clipboard manager.

P.S. I recommend changing/disabling its Win E shortcut as that conflicts with Windows built-in shortcut for file explorer
