Change Dyslexia

Our dream in Change Dyslexia is to eliminate school failure as a primary way dyslexia is identified. Change Dyslexia is a non-for profit organization that brings research based solutions for people with dyslexia. The tools focus on early identification (Dytective) and intervention (Piruletras/Dyseggxia).


Each person in Change Dyslexia offer the best they can do: research in differents areas, software development, and design, among others. The amazing teams are lead by Luz Rello, Ashoka Fellow and Special Faculty at Carnegie Mellon University

Early Detection - Dytective


Dytective is a game that aims to identify and improve linguistic and attention abilities of people with dyslexia. Currently, we are conducting research to improve its accuracy.

A Computer-Based Method to Improve the Spelling of Children with Dyslexia

Luz Rello, Clara Bayarri, Yolanda Otal, Martin Pielot

In collaboration with CREIX Barcelona a Lestonnac School we evaluated Piruletras with 48 children with diagnosed dyslexia and after playing Piruletras (Dyseggxia) for four weeks in a row they had significantly less writing errors. It is available for English, Spanish and German. Winner of the first prize of the Vodafone Foundation Mobile for Good Europe Awards 2013.
