A great working immersive reader extension! Great job
she is now much happier about the...
I have been trying to find ways to make my child happy to go to school again, and someone recommended helperbird. She loves helperbird, and she is now much happier about the idea of returning to school. I think this might be a game changer, as they do so much web based schoolwork and research. She says they really understand people with dyslexia
Great features on the free side.
