Simplemente increíble. Nunca he tenido una extensión con tantísimas opciones juntas. Como profesor, siempre la recomiendo a las familias de estudiantes con dificultades para mantener la atención, a la hora de leer, y otras necesidades específicas, aunque pienso que puede ser de uso para cualquiera. ¡Un 10!

Helperbird does so many things that are game changing for me! By far the two most important are the font changes and the highlight ruler. I can change fonts to something dyslexia friendly. The ruler helps me stay on the line I'm trying to read. These two things change the blur into words! Tech support has been great when I have had problems!

Have an amazing collection of assistive tools that have benefits for everyone. For me, the combination of Microsoft's Immersive Reader and Apple's reading machine voice (US Alex) makes Helperbird my first choice for processing web content.
