What does everyone use?

I'm trying to show quoted text on, well, Twitter and want to use a highlighter on the Internet without using a highlighter in real life.

Then save the image and show everyone what I have.

It sucks because Adobe Acrobat is trash. I can't believe I got desperate enough to pay for it today.

The OCR capabilities are horrible and Adobe Scan just doesn't work for me, I feel, because I can't keep the physical copy pages still...

So now I'm back to just wanting to take a picture and put high-lighter text on an image rather than the actual pages (I probably should get used to annotating and highlighting text physically but I'll walk that bridge when I get there...)

What should I use?

I can't Internet to save my life...
