Textgrabber for free

Hi there! I'm Jayson. I'm just wondering if there's Textgrabber app for free and/or another likely app which is same as Textgrabber? What do you know about Talking Goggles, that I read about yesterday? I did not get it to work actually. I had chose correct language, then set the flash on and after that take a picture, but nothing happened.
