Having worked on a product that actually did this, it's not as easy as it seems. There are many ways of drawing text on the screen.
GDI is the most common, which is part of the windows API. But some applications do their own rendering (including browsers).
Another difficulty, even if you could tap into every draw call, you would also need a way to determine what is visible on the screen and what is covered by something else.
