Capture2Text is a surprisingly simple (and portable) OCR tool.

The program can capture text from anywhere on your screen, for instance. Just move your mouse cursor to the top left of the text; press the hotkey (Win+Q by default); move the mouse cursor to the bottom right of the text; click the left mouse button, and the decoded text ends up in the clipboard.

If any of this doesn't work quite as you expect then there are lots of configuration options which can help. You're able to customise the hotkeys, set a new language for OCR, or maybe tweak the output settings so the text goes directly to a program, rather than the clipboard.

We had a few problems when testing the program. The hotkey didn't work consistently, for instance. And the OCR accuracy was generally poor.

There are plenty of issues which may influence this, though, so if you're interested in the core idea then there's no harm in giving the program a try: you may have more luck.

Version 3.6:
    - Removed the experimental speech recognition feature due to new Google Speech API v2 quota restrictions.
    - Fixed DPI scale issue with the capture box.
    - Now compiled with AutoHotkey 32-bit Unicode v1.1.22.00 (was v1.1.14.03).

Verdict

Capture2Text wasn't accurate enough for us, but the program is also compact, convenient and easy to use - if you're interested in the core idea, we'd recommend you try it anyway, see what it can do for you
