Hi Kaitlyn, Sorry; I've only seen a Braille Sense once, being shown to me by a demonstrator with an almost impenetrable Korean accent. I liked the unit, and think you could validate with it. I can't give you specifics, but maybe a couple of general pointers. First and foremost, you need to keep the file in its original format. If the Braille Sense can work with rtf files, then validating with it will work for sure. Open the file and do the editing you want for that time, then save and make sure it stays in rtf and doesn't end up in a grade 2 format, or brl or brf file. If that's doable, you should be able to choose to do your validating on the device and cut out the middleman, so to speak. Hope this helps, Kellie
